The liver helps to maintain blood sugar level by storing excess glucose present in the blood as glycogen (glycogenesis) and converting it back to glucose when the blood glucose level is low (gluconeogenesis).

This glycogen is converted back to glucose whenever the body needs glucose, and blood glucose levels are low. They also take part in the detoxification, modification, and excretion of chemicals.Įxcess glucose present in the blood is stored in the form of glycogen in the liver.

The liver is an accessory organ of the digestive system, not part of the main path of the food. It produces bile: a digestive juice that is required for the breakdown of fatty components of the food in the duodenum. The liver, the largest internal organ in humans, plays a vital role in the digestion of fats and detoxifying the blood.
