Concept Explanation
 

Liver

Liver : It is the  largest gland of the body. It performs many functions. It secretes bile, which helps in digestion. Bile juice is produced by the liver is stored in the ‘gall bladder’. There are two functions of bile:

  • It emulsifies fats by rendering them soluble and breaking them into small globules. In this form, fats are better exposed to the action of fat - hydrolyzing enzymes. (All digestive enzymes catalyze by breaking water molecule and are hence called hydrolyzing enzymes.)
  • The acidic food (chyme) coming from stomach becomes alkaline (chyle) when it is mixed with bile. This is important as the intestinal enzymes catalyze the breakdown of food only in an alkaline medium.
  • It is responsible to excrete cholestrol, bilirubin, drugs and hormones.
  • It stores vitamins, minerals and glycogen.
  • It detoxifies the blood and purifies it.
  •
