Gametes have how many pairs of chromosomes?

76% Answer Correctly

The small intestine utilizes enzymes produced where?

65% Answer Correctly

	small intestine
	pancreas
	all of these are correct

Solution

The small intestine is where most digestion takes place. As food travels along the small intestine it gets broken down completely by enzymes secreted from the walls.

After the enzymes break down the food, the resulting substances are then absorbed into the blood via capillaries in the small intestine walls.
