Which is longer: small intestine or large intestine?

1

Why is the small intestine this long?

2

1

What is the liver's role in digestion?

1

What is the function of the gall bladder?

1

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).

1

In the image above, which number is the pancreas?

1

Where pepsin is active:

1

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)
