What parts of the body are used in the digestion of lipids?
Mouth
Stomach
Duodenum
Ileum
What happens to lipids in the mouth?
The food is chewed
What happens to lipids in the stomach?
The heat from the stomach melts the fat which increases the surface area for digestion
What is the duodenum?
It is the first part of the small intestine

Pancreatic juice from the pancreas contains the enzyme lipase which begins to break the fats into fatty acids and glycerol
What is the ileum?
The last part of the small intestine
What happens to lipids in the ileum?
Intestinal juice containing lipase finishes the breakdown of fats into fatty acids and glycerol
What enzyme is involved in the digestion of lipids?
Lipase
Where in the body does the enzyme lipase break down lipids?
The duodenum and ileum
What substance emulsifies fats in the duodenum?
Bile
Lipase is an enzyme found in which bodily fluids?
Pancreatic juice
Intestinal juice
What is the function of lipase?
It breaks down lipids into fatty acids and glycerol
Where does bile come from?
The liver
Where in the body does bile emulsify fats?
The duodenum
How does the pancreas contribute to the digestion of lipids?
The pancreas produces pancreatic juice which is secreted into the duodenum of the small intestine where it’s enzyme lipase breaks down lipids into fatty acids and glycerol
