If villi of the small intestine are damaged why may a person feel weak even after eating food?
Answer and explanation
Correct answer: Absorption of nutrients will decrease
Digestion breaks food into small molecules, but the body can use them only after absorption. Villi normally increase the intestinal surface area and provide thin routes into blood and lymph. If villi are damaged, less glucose, amino acids, fatty-acid products, vitamins, and minerals enter circulation, causing poor nourishment and weakness even when food is eaten. Hence option A is correct.
