Question

State the role of liver in excretion.

Answer 1

The role of the liver in excretion:

1. The liver is the largest gland present in the human body.
2. It helps in the excretion of vitamins, drugs, steroid hormones, and waste material through bile.
3. The liver converts the amino acids present in the blood into ammonia and pyruvic acid.
4. Pyruvic acid gets oxidized to release energy, and ammonia gets converted into urea.
5. The kidney helps in the filtration of the urea, and urea gets excreted in the form of urine.
6. The liver excretes bilirubin which is a by-product of hemoglobin catabolism.
7. Bile gets excreted in the small intestine and excreted in the form of faeces in the large intestine.
