Question

Which of the following correctly describes the structure and its function? Cardiac sphincter; controls what food enters the stomach
Stomach; mixes chum and food
Small intestine; absorbs fats and fatty acids
Colon; food is chemically digested

Answer 1

Answer:

Option C, Small intestine; absorbs fats and fatty acids

Explanation:

We will look at the functions of all the given structure

a) Cardiac sphincter - Just like a cardiac system it prevents the back movement of food from stomach to esophagus.

b) Stomach - digestive enzymes and acid act on the food to digest it.

c) Small intestine - its main function is to absorb nutrients and minerals from food. Thus, absorption of fats and fatty acids is the right function of small intestine

d) Colon - it forms stool after the re-absorption of left out minerals and fluid in the digested food passed on by the small intestine.

Thus, option C, is correct.

Answer 2

The correct description of structure and function is the small intestines; absorbs fats and fatty acids. The cardiac sphincter prevents the acidic contents of the stomach from moving upward into the esophagus. The stomach is where digestion takes place, both mechanical and chemical digestion
