Which is the largest digestive gland present in human body? What is the name andfunction of its secretion?

The largest digestive gland present in the human body is the liver.

The liver secretes a substance called bile. Bile has two main functions:

1. Emulsification of fats: Bile breaks down large fat globules into smaller ones, a process that is important because it increases the surface area of the fats, making them more accessible to the digestive enzymes.

2. Excretion of waste products: Bile also helps in the excretion of waste products such as bilirubin (a product of red blood cell breakdown) and excess cholesterol. These waste products are eliminated from the body in the feces.
