Identify the structure (its the thin membrane attached to the small intestine)

Question 12

Which is longer: small intestine or large intestine?

Question 13
13.

Why is the small intestine this long?

Question 14
14.

Most food stuffs are absorbed in the small intestine, but what IS absorbed in the large intestine?

Question 15

Question 17
17.

What is the liver's role in digestion?

Question 18
18.

What is the function of the gall bladder?

Question 19
19.

Bile aids in the breakdown of:

Since fats and water dont mix, bile emulsifies the fat into microscopic droplets to aid in their digestion.
As you can see from this picture, bile can be released from the liver directly into the small intestine via the hepatic duct into the common bile duct. If bile is not needed at the time, it can divert into the gall bladder via the cystic duct (a sphincter prevents it from going into the duodenum).

In the image above, which number is the pancreas?

Question 24
24.

Where pepsin is active:

Question 25
25.

Where trypsin is active:

The pancreas produces a number of enzymes that aid in digestion. These enzymes may flow into the small intestine via the common bile duct (exocrine), or they may enter the bloodstream (endocrine)
