Include enzymes and hormones that assist in digestion and the source of the secretion. a. b. Which of the above is the major site of lipid digestion and absorption?

Answer 1

It is the small intestine which is the major site of digestion of fat.This is acheived with help of bile produced by liver and secreted by the gallbladder which emulsifies the fat globules into small fat droplets called miscelles which are then carried to intestineand are converted to chylomicrons which are water soluble and can travel in blood stream.

Pancreatic lipase is an enzyme responsible for digesting fats.

The portion which is orange(small intestine) in color inside green (large intestine) is major site of lipid absorption and digestion.
