Explain the role of liver in our body.
Answers
Answer:
The liver filters all of the blood in the body and breaks down poisonous substances, such as alcohol and drugs. The liver also produces bile, a fluid that helps digest fats and carry away waste. The liver consists of four lobes, which are each made up of eight sections and thousands of lobules (or small lobes)
Required Answer
liver is the largest gland of body. It is multi-lobed and dark reddish in appearance. It lies beneath the diaphragm on the right side of abdomen. In an adult human, it weighs about 1.5 kg and is the size of a football.A pear-shaped greenish yellow sac i.el.gallbladder lies along the right lobe of liver on ventral side.
Liver secretes bile, which is stored in gallbiadder. When gallbladder contracts, bile is released into duodenum through common bile duct. Bile has no enzymes but contains bile salts for the emulsification of lipids. It helps the lipid-digesting enzymes to attack on lipids. Besides digestion, liver carries out a number of other functions, some of which are summarized here:
- Removes amino groups from amino acids (de-amination)
- Converts ammonia to a less toxic form i.e urea.
- Destroys the old red blood cells.
- Manufactures blood clotting proteins called fibrinogen.
- Converts glucose into glycogen and, when required, breaks glycogen into glucose.
- Converts carbohydrates and proteins into lipids and produces cholesterol.
- Produces heat to maintain body temperature.
- Stores fat-soluble vitamins (A, D, E, and K) and mineral ions, such as iron.
