Question

what happens to food in the small intestine? check all that apply. food is cut into smaller pieces. blood in the villi helps to absorb nutrients and sugar molecules. nutrients from food are absorbed. food is squeezed and made watery. fat is broken down into smaller droplets.

Explanation:

• "Food is cut into smaller pieces" occurs in the mouth (mechanical digestion by teeth), not the small intestine.
• "Blood in the villi helps to absorb nutrients and sugar molecules": Villi in the small intestine have blood capillaries that absorb nutrients (including sugars) into the bloodstream.
• "Nutrients from food are absorbed": The small intestine is the main site for nutrient absorption (e.g., amino acids, fatty acids, vitamins, minerals, sugars).
• "Food is squeezed and made watery" is part of churning in the stomach or peristalsis in the small intestine but the main function of the small intestine is absorption, and this description is more associated with earlier digestive stages or general peristalsis, but the key absorption function is more defining. However, the main absorption - related correct ones are the nutrient absorption and villi - related. Also, fat is broken down into smaller droplets (emulsification) by bile in the small intestine (before chemical digestion of fat by enzymes). Wait, actually, "Food is squeezed and made watery" is more of the stomach's churning or the action of peristalsis but the small intestine does have peristalsis, but the main functions are digestion (final stages) and absorption. Let's re - evaluate:
• "Blood in the villi helps to absorb nutrients and sugar molecules": Correct. Villi have a rich blood supply to absorb nutrients.
• "Nutrients from food are absorbed": Correct, as the small intestine is the primary site for nutrient absorption.
• "Fat is broken down into smaller droplets": Bile (released into the small intestine) emulsifies fat into smaller droplets, so this is correct.
• "Food is cut into smaller pieces": Mouth (teeth) - incorrect.
• "Food is squeezed and made watery": Stomach (churning) or general peristalsis, but the main function of the small intestine is not primarily this - incorrect.

Answer:

• B. Blood in the villi helps to absorb nutrients and sugar molecules.
• C. Nutrients from food are absorbed.
• E. Fat is broken down into smaller droplets.
