Digestion of fats

Answer 1

The digestion of fats is accomplished in two stages. First the emulsification stage requires bile to break the fat down into smaller particles, then the pancreas secretes pancreatic lipase which then breaks it down further to where it can be taken up by a lacteal into the lymphatic system.

Answer 2

Digestion of fats and other lipids begin in the small intestine and relies on the production of bile. Bile contains salts, which act as detergents (emulsifiers) that aid in digestion and absorption of lipids. In the small intestine many nutrients leave the intestine through the bloodstream, some products of fat (triglyceride) take a different path: After being absorbed by epithelial cells, fatty acids and monoglycerides (glycerol joined to a single fatty acid) are recombined into triglycerides within those cells. These fats are then coated with phospholipids, cholesterol and proteins forming water-soluble glubules called chylomicrons. These globules are too large to pass through the membranes of capillaries. Instead they are transported into a lacteal, a vessel at the core of each villus of the intestinal wall. Lacteals are part of the vertebrate lymphatic system.
