WHICH IS THE LARGEST GLAND IN OUR BODY?

WHICH IS THE LARGEST GLAND IN OUR BODY?
Liver is the largest gland in our body.Liver secretes bile juice which helps in breaking down of large globules into small globules this process is known as 
emulification.

 Liver is a large organ that sits on the right side of belly which is reddish brown in colour and protected by ribcage and gall bladder sits under the liver along with pancrease and intestine.

 FUNCTION OF LIVER:-

 * Liver help in filtering the blood.

 * Liver help in protein for clotting of blood.

 DIGESTION IN HUMAN BEINGS:
Whenever we eat food then we chew it,grind it,tear it using our teeth and saliva present in our mouth contains an enzyme known
as salivary amylase which break down starch into simple sugars then food travels.

 Along the elemantary canal then it reach stomach  where gastric gland release HCL which help an protein enzyme pepsin help in changing protein into protease and mucus protect the inner lining of stomach from acidic medium created by HCL.

  Then the food reach small 
intestine it can be completely 
digested here through bile juice 
and trypsin then after breaking 
down of this the food materials get
 excreated by anus.

 VILLI:

 Villi is present in small intestine help in increasing the surface area of small imtestine.

DIGESTION

Disegion , gland
DIGESTION
METABOLIC PROCESS:

 The process which are not in our
 control.

 Example: Digesion,Respiration,
Excreation and Transportation.

 DIGESTION:

Digestion is a metabolic process in which the complex food is break down into simpler ones by catalyst.

DIGESTION PROCESS
CATALYST:

 Involving reaction.

 SALIVARY GLANDS:

 There are three salivary gland 
present in the mouth which secrete saliva(water) which convert starch
 into simple sugar.

 PERISTALISIS:

Peristalisis is a movement of muscles in elementary anal which push the food forward.

 LIVER:

Liver release bile juice.And it is a largest gland in our body.

 PANCREATIC GLAND:

Pancreatic gland release pancreatic juices like trypsin.

 GASTRIC GLAND:

Gastric gland release hydrochloriccid which create an acidic medium in stomach.

 Hydrochloric acid  helps a enzyme present in stomach.

 i.e pepsin to breakdown proteins and to protect our stomach from this acid there is one more thing mucus.

 Breaking down of food in stomach:-

 Breaking of this food starts in mouth .In mouth there are three salivary glands which release an enzyme known as salivary amylase.

 This enzyme breakdown starch then the food pass through foodpipe and when reach stomach breakdown again gets started.

 Liver secretions bile juice helps to breakdown fat globules and this process is known as emulsification and other nutrients also gets breakdown by lipase and pancreatic secretions and then all food goes to anus by help of anus sphincter.

 Mind one more thing the complete digestion  happens in small intestine but size of small intestine differ in all ex. cow eats grass which contains cellulose and it is not easily digestable and they need larger small intestine and animals need small intestine.

 Villi:


 This is present in small intestine to increase or to decrease size of small intestine.

 DIGESTION IN PLANTS:

 Plants are autotrophic(those who make there own food).Plants make there own food through the process of photosynthesis.

 PHOTOSYNTHESIS: HOW THIS PROCESS WORK ?

 There are some green dots in the leafs of plants which are known as chloroplast which contains some pigments known as chlorophyll whuch are green in colour and gives green colour to leafs.

 * There are important factors which are needed for photosynthesis which is sunlight and carbon dioxide ( co2),chlorophyll, water.

The raw material for photosynthesis are carbon dioxide and water.The end products of photosynthesis is glucose(carbohydrate) and oxygen.

 Carbojydrates are utilised for providing energy to the plant.The remaining carbohydrates,which are not used immediately are stored in the form of starch.It serves as the internal energy reserve and is used by the plant whenever required.Glycogen serves as an internal energy reserve to be used when required in animals.

 EVENTS IN PHOTOSYNTHESIS:

 Major events that occur during the process of photosynthesis are:-

 * Absorption of light energy by chlorophyll.

 * Conversion of light energy into chemical energy and splitting of water molecules into hydrogen and oxygen.

 *  Reduction of carbon dioxide to carbohydrates.
