We will now consider the secretions involved in fat digestion, including the organs that secrete or release them. review the list of the various molecules involved in fat digestion below and match the molecules with their correct organ of origin or storage.

I cannot find the list of molecules and organs, but I gonna explain all existing lipid digestion.
First, you should know that triglycerides are not absorbable. The absorbable substances are free fatty acids, monoglycerides and cholesterol.

The main stages of lipid digestion:-Fat emulsification;
-Hydrolysis of lipids (by enzymes);
-Formation of micelles;
-Endocytosis of the micellar contents.

The enzymes responsible for lipid hydrolysis are:
lipases (pancreatic): secreted by the exocrine pancreas
colipase: secreted by the pancreas in an inactive form. Its role is to help the lipase in its activity.
cholesterol esterase: secreted by the pancreas too.
phospholipase A2: exists in the majority of the cells

It is evolution, because we all have some of the same traits like eye color or shape or ears.
