LIFE PROCESSES

LIFE PROCESSES  

All the plants and animals (including human beings ) are alive or living things.

The most important test to decide whether something is alive or not is the movement. the movements in most of the animals are highly and can be observed easily but the movement in plants are usually slow and observed with difficulty.

frog move when it jump into a pond, 

All animals can transfers from one place to another or they can move there body parts. For exp a frog move when it jump into a pond, a bird move when it flies in the sky, an athlete moves when he runs.

bird move when it flies in the sky

The plants are fixed in the soil at a place, so they cannot move like animals from like from place to place. The plants can only move some parts of there body such as leaves, flowers, shoots and roots. The plant parts move towards a upgrade such as sunlight, gravity or water, etc. for example, the shoot, the leaves and flower of a sunflower plants move by bending towards the sun so as to face the sunlight. The leaves of a mimosa pudica plant  (sensitive plant) move folding up when touched with a finger. Plants also show movement by growing their root and shoots bigger.

What is life process

The basic work performed by living organisms to handle their life on this earth are called life processes. Nutrition and respiration; Transport and Excretion; Control and Coordination ; Growth; Movement and Reproduction.

ENERGY IS REQUIREMENT FOR THE LIFE PROCESSES

They get this energy from food. Food is work as a kind of fuel which provides energy to all living organisms. The energy requirement by an organism comes from the food that the organism eats.

Now start with nutrition

NUTRITION

FOOD is an organic substance. The effortless food is glucose. It is also called simple sugar. A more difficult food is starch. Starch is made from glucose. The common name of substance like glucose (sugar ) and starch is ‘carbohydrates’. Carbohydrates are the most general food for getting energy. Fat and proteins are also foods. Definition of food, however also include mineral salts, vitamins and water which are need and utilizing it is called nutrition.

TOOLS OF NUTRATION        

Nutrition

There are two tools of nutrition;

1 Autotrophic, and

2 Heterotrophic.

1 Autotrophic tool of Nutrition

   The word ‘auto’ means ‘self’ and ‘trophe’ means ‘nutrition’. that means ‘self nutrition’. Autotrophic nutrition is that tools of nutrition in which an organisms make its own food from the easy inorganic materials like carbon dioxide and water present in the surroundings (with the help of sunlight energy ).the green plants have an Autotrophic mode of nutrition.

The Autotrophic organisms implant the green pigment called chlorophyll which is able of catch sunlight energy.

2 Heterotrophic tool of nutrition

Heteros means others and trope refer to nutrition that means nutrition get from others. Heterotrophic nutrition is that tools of nutrition in which an organisms cannot made its own food from simple inorganic materials like carbon dioxide and water and depends on other organisms for its food. Animals have a Heterotrophic mode of nutrition. the non-green plants (like yeast) are also Heterotrophs.

NUTRITION IN PLANTS

THE proceeds by which green plants make their own food (like glucose ) from carbon dioxide and water by using sunlight energy in the presence of chlorophyll, is called photosynthesis.  Oxygen gas is released during photosynthesis.

  Photosynthesis

  Photosynthesis represented as

6CO2    +   6H2O   +   Light energy                                           C6H12O6  +  6O2

The process of photosynthesis takes place in the green plants. The green plant made the food by adding carbon dioxide and water in the presence of sunlight and chlorophyll. The carbon dioxide gas need for making food is taken by the plant leaves from the air. This carbon dioxide enters the leaves through small gape in them called stomata. Water need for making food is taken from soil. This water is carry to the leaves from the soil through the roots and stem. The sunlight given energy needed to pass out the chemical reaction include in the preparation of food. The green pigment called chlorophyll present in green leaves helps in taking energy from sunlight. Oxygen gas is produced as a by- product during the making of food by photosynthesis. The oxygen gas goes into the air.

The food prepared by the green leaves of a plant is in the form of a simple sugar called glucose. This glucose food made in the leaves is then transfer to the different part of plants. The remain glucose is changed into another food called starch.this starch is stored in the leaves of the plant.

NUTRITION IN ANIMALS

Animals make their food from plants or other animals

Animals cannot made their own food, they depend on readymade food. This readymade food from plants or from other animals. Human beings are also animals. We get the food like wheat, rice pulses fruits and vegetables from plants. And the food like milk, curd, cheese and eggs are get from animals. Some people also eat meat, chicken and fish as food. Even some of the plants can eat insects. Venus fly- trap is one such plant.

All the animals can be separate into three groups on the basis of food habitsare;

1 Herbivores,

2 Carnivores

3 Omnivores

1 herbivores
    

 herbivores

Those animals which eat only plants are called herbivores. The herbivores may eat grasses, leaves, grains, fruits or the bark of trees. Herbivores are; goat, cow sheep deer camel ass monkey squirrel and rabbit.

2 Carnivores; those animals which eat only other animals as food are called carnivores. There are Lion, Tiger ,Frog, Lizard, Wolf, Snake and Hawk.

Carnivores

3 Omnivores; those animals which eat both plants and animals, are called omnivores. Omnivores are Man ( human beings) ,dog, crow, sparrow, bear and ant. Omnivores are plant eater as well as meat eaters.

Omnivores

Nutrition in human beings

(Human digestive system)

(Human digestive system)

The different organs of the human digestive system in sequence are : Mouth, Oesophagus  (food pipe ), Stomach, Small intestine and Large intestine. The glands which are companion with the human digestive system and form a part of the human digestive system are : Salivary glands, liver and pancreas.

1 Ingestion

The human being have a special organ for the ingestion of food. It is called mouth. So, in human beings, food is ingested by the mouth. The food is take into the mouth with the help of hands.

2 Digestion

 In human beings the digestion of food begins in the mouth itself. In fact the digestion of food starts as soon as we put food in our mouth. The become as follows: the mouth cavity contains teeth, tongue, and salivary glands. The teeth cut the food into small pieces, chew and grind it. The teeth help in physical digestion. salivary glands help in chemical digestion by secreting enzymes. The gastric juice contain three substance: hydrochloric acid, the enzyme pepsin and mucus. The enzyme pepsin begin the digestion of protein present in food to form smaller molecules. From the stomach, the paretially digested food enters the small intestine.

The small intestine in human beings is the site of complete digestion of food (like proteins, carbohydrates and fats).

The small intestine receive the secretion of two glands Liver and Pancreas.

The walls of small intestine contain glands which secrete intestinal juice. the chemical digestion of food is brought about by biological catalysts called enzymes.

3 Absorption

After digestion the molecules of food become so tiny that they can pass by the walls of the small intestine and go into our blood. This process called absorption. The small intestine is especially adapted for absorbing the digested food. The inner surface of small intestine has millions of small, finger- like projections called villi.the presence of villi gives the inner walls of small intestine a very large surface area.

4. Assimilation 

   The blood transfer digested and dissolved food to all the parts of the body where  it becomes assimilated as part of the cells. This assimilated food is used through the body cells for obtaining energy as well as for growth and repair of the body. The power is released through the oxidation of assimilated food in the cells during respiration. The digestive food which is not used through our body immediately is store in the liver in the form of a carbohydrate called glycogen.this stored glycogen can be used as a power through the body when it is need.

5. Egestion

 A part of food which we  eat but cannot be digested by our body. This undigested food cannot be absorbed in the small intestine. So, the undigested food transfer from the small intestine into a wider tube called large intestine. The walls of large intestine absorb most of the water from the undigested food. Due to this, the undigested part of food becomes almost solid. The last part of t5he large intestine called ‘rectum’ stores this undigested food for some time. And when we go to thje toilet, then this undige3sted food is transferred out from our body through anus as  faeces or ‘stool’. The act of expelling the faeces is called egestion or defecation. The exit of faeces is controlled by the anal sphincter.

What Is a Coronavirus?

WHO

 coronavirus

Coronaviruses were first identified in the 1960s, but we don't know where they come from. They get their name from their crown-like shape. Sometimes, but not often, a coronavirus can infect both animals and humans.

Most coronaviruses spread the same way other cold-causing viruses do: through infected

Almost everyone gets a coronavirus infection at least once in their life, most likely as a young child. In the United States, coronaviruses are more common in the fall and winter, but anyone can come down with a coronavirus infection at any time.

 coronavirus

As per state-owned CCTV, the new coronavirus is different from human coronaviruses already known. WHO said in a statement that further investigations are required to determine the source, modes of transmission and extent of infection caused by the new virus.

About 858 people have died from Middle East respiratory syndrome (MERS), which first appeared in 2012 in Saudi Arabia and then in other countries in the Middle East, Africa, Asia, and Europe. In April 2014, the first American was hospitalized for MERS in Indiana and another case was reported in Florida. Both had just returned from Saudi Arabia. Coronavirus scare in India: Nearly 100 people under observation, PMO reviews preparedness

Common Symptoms of Coronavirus

The symptoms of most coronaviruses are similar to any other upper respiratory infection, cold, runny nose and sometimes a fever. In most cases, you won't know whether you have a coronavirus or a different cold-causing virus, such as rhinovirus.       

 coronavirus

Coronavirus treatment

There is no specific treatment, but research is underway. Most of the time, symptoms will go away on their own and experts advise seeking care early. If symptoms feel worse than a standard cold, see your doctor.

Doctors can relieve symptoms by prescribing a pain or fever medication.  a room humidifier or a hot shower can help with a sore throat or cough.

Drink plenty of fluids, get rest and sleep as much as possible.

The death toll from the coronavirus climbed above 1,000, as the Chinese province at the epicenter of the outbreak reported its highest number of fatalities yet.

Hubei province added 103 more deaths, up from 91 a day earlier. At the same time, it also reported the lowest number of new cases since Feb. 1, an encouraging sign as health officials look for the outbreak to

Physiological changes due to ageing

Physiological changes due to ageing

Meaning of ageing

ageing

Ageing is an inevitable and extremely complex, multi-factorial process. It s characterized by the progressive degeneration of organ system and tissues. It is largely determined by genetics ad influenced by a wide range of environmental factors such as diet, exercise, exposure to microorganism, pollutants, radiation, etc.

PHYSIOLOGICAL CHANGES DUE TO AGEING

The various physiological function reach their peak approximately during20 to 30 years. The research studies conducted in this field show that most of the system or functions after reaching their peak start  decreasing gradually with age. most of the research studies also show that most of the organs seem to lose physiological functions at about 1% a year beginning around 30 years of age.

ageing

The major physiological changes due to ageing given bellow

1.   Changes in muscle size and strength: when an individual gets older, there is a decline in muscle size there is a decrease I muscle mass and increase in over all body fat. The decreasing in strength gradually occurs during the age of 35-45 years. However even at the age of 6 the decrease in strength does not appear to exceed 20% of an individual’s maximum strength.

2.   Changes in metabolism and body composition: with advancement of AGE our body need less energy and the metabolism slows down. Consequence there is an increase in the accumulated o body fat and therefore the lean body weight (bones ligaments, tissues, tendons, muscles and water) decrease. The metabolic rate decrease gradually with the increase age. It also result in more accumulated of body fat.

3.   Change in bone density : : with advancement of AGE the bone density decrease. It means that the elderly people especially those over 40 years of ages are minerals such as calcium and phosphorus found in bones. bone become less dense and more porous.

4.   Change in respiratory system: a number of studies show that pulmonary function is impaired with advancing age. He airways and lunges tissues become less elastic. The become less efficient there is decreased oxygen uptake and oxygen exchange. the muscles of ribcage become weak. Hence the ability to breathe deeply is reduced.

5.   Change in cardiovascular system: with advancing age, there is a progressive decrease in cardiac muscle strength. The stroke volume cardiac output and blood flow are al decrease with age. Blood vessels also lose their elasticity. They become more and more rigid. Systolic blood pressure also increases with age. The reduced blood flow results in reduced endurance. There is less nourishment to cells of body. Heart valves become less flexible.

6.   Change in nervous system: a number of research studies indicate that reaction time and movement time slow down with increase age. The brain’s weight, the size of its network and its blood flow decrease with age. However, the brain adapts to these changes, growing new patterns of nerve endings. To recall old memories becomes slow.

7.   Change in the gastrointestinal system: with increase age, there is a reduction in the production of hydrochloric acid, digestive enzymes and saliva. These change may result in delayed emptying of stomach impaired swallowing. The breakdown and absorption of food may also be impaired. The liver become less efficient in metabolizing drugs and repairing damaged liver cells.

8.   Change in urinary system: as we grow old the mass of the kidneys decreasing. This leads to reduction in the rate of blood filtration by the kidneys. The capacity of bladder decreases and there is an increases in residual urine. These changes increase the chances of urinary infections. With increasing age, it takes a long time four kidneys to get rid of waste products. These substances tend to remain in the body for a longer period of time.

9.   Changes in flexibility: the elasticity of tendons ligament and joint capsules is decreased with ageing .the elderly persons lose 8-10 cm of lower back and hip flexibility   according to a research  study.    

10.                     Change in senses; with advancing age the senses such as vision hearing ,taste, smell, touch,. may become less acute. Vision and hearing are most affected by ageing.

ROLE OF PHYSICAL ACTIVITY IN MAINTAINING FUNCTIONAL FITNESS IN AGED POPULATION

No one can stop the clock of ageing, but every person can slow down its pace with the help of physical activity. As a matter of fact physical activity can play a significant role in maintaining functional fitness in aged population. Physical activity is the most powerful tool in the hands of aged people that it can improve, as maintain their functional fitness effectively. regular physical activity can play an effective role in maintaining functional fitness but it should be implemented in a proper way. First of all, aged people should consult a doctor regarding their level of physical fitness and health. The recommended amount of physical activity should not more than their capacity. The physical activity prescription for aged people should include aerobic, muscle strengthening and flexibility exercises. Regular activity can play an effective role in maintaining functional fitness in aged population in the following ways.

1.   Reduce the loss of muscle mass: muscle mass decreases with advantage age. Ageing has a negative effect on metabolism. Regular physical activity decrease the loss of lean body mass and drop in the metabolic rate. Regular physical activity also reduces the accumulation of fats.

2.   Help in maintaining bone density: bone density decreases with age. It usually leads to fracture and osteoporosis. Physical activity helps to maintain bone mass and prevents  osteoporosis. Resistance exercise stimulate bone growth.

3.   Slow down brain ageing: the regular physical activity reduce the risk of mild cognitive impairment. It is a condition characterized by memory and thinking problem. mild cognitive impairment. May lead to dementia later on. Regular physical activity improves memory and cognitive skills. It stimulates the growth of new nerve cells and builds new capillaries to supply the brain with more oxygen.

4.   Reduces the risk of age-related diseases: regular physical activity reduces the risk of number of health problems related to ageing. Such health problems are type 2 diabetes, obesity, hypertension, heart diseases, etc. regular physical activity decreases blood sugar level, decreases LDL (bad cholesterol), increases HDL(good cholesterol), decreases blood pressure and decreases blood vessel stiffness. It can be alluded that physical exercise reduces the risk of diseases related to ageing.

Improves muscular strength: ageing process does not hinder the individual’s ability to enhance muscles. As a matter of fact, physical activities increase the size of muscles which ultimately  increase muscular strength

HOLI HD PHOTOS

, is observed on the full moon day of Hindu month Falgun. On the next day, festival of colors (also kown as dhulendi,dhulandi,and dhuli) is celebrated. Celebration of Holi mark the victory of god over evil.

History of holika dahan

Holi has been witnessed for a very long time. There is a picture found from the 16^th century in the capital of ancient Vijayanagara Empire, hampi. This image shows the celebration of holi.

Similarly, at ramgarh, close to vindya mountains a 300 BC old inscription has found which holds the description about holi. Some people thinking that on this day ,lord Krishna had killed a demoness name Pootna.

What are the reason of holika dhan

As per the hindu puranas, when hiranyakashyap (the king of the demons) observed that his son prahlad worships lord Vishnu, he got really furious. He ordered his sister holika to sit in the fire while holding prahlad in her lap. It is because holika was blessed that she cannot be burned in the fire. however, things did not go as per the plan. Holika got burned into ashes in the fire and nothing happened to the Vishnu dwvotee prahlad. In the memory of this vent, there is the canon of performing holika dahan. The festival of holi gives a message that this is how almighity stays available to protect his devotees.
