1

What parts of the body are used in the digestion of lipids?

Mouth
Stomach
Duodenum
Ileum

2

What happens to lipids in the mouth?

The food is chewed

3

What happens to lipids in the stomach?

The heat from the stomach melts the fat which increases the surface area for digestion

4

What is the duodenum?

It is the first part of the small intestine

5

What happens to lipids in the duodenum?
(2)

Bile from the liver emulsifies the fats

Pancreatic juice from the pancreas contains the enzyme lipase which begins to break the fats into fatty acids and glycerol

6

What is the ileum?

The last part of the small intestine

7

What happens to lipids in the ileum?

Intestinal juice containing lipase finishes the breakdown of fats into fatty acids and glycerol

8

What enzyme is involved in the digestion of lipids?

Lipase

9

Where in the body does the enzyme lipase break down lipids?

The duodenum and ileum

10

What substance emulsifies fats in the duodenum?

Bile

11

Lipase is an enzyme found in which bodily fluids?

Pancreatic juice
Intestinal juice

12

What is the function of lipase?

It breaks down lipids into fatty acids and glycerol

13

Where does bile come from?

The liver

14

Where in the body does bile emulsify fats?

The duodenum

15

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

16

What is the function of intestinal juice?

It contains the enzyme lipase which breaks lipids into fatty acids and glycerol
