Question

Quizplus · Accepted Answer

The large intestine is responsible for reabsorbing water and compacting feces, which results in the elimination of solid waste.

Answer: A
 The large intestine also absorbs bile salts, which are produced in the liver and stored in the gallbladder, and then released into the small intestine to aid in fat digestion.

Answer: B
 While the large intestine doesn't secrete many vitamins, it does produce some vitamins via the action of bacteria living in the colon. However, the majority of vitamins are absorbed in the small intestine.

Answer: D and E
 The large intestine does produce gas as a byproduct of bacterial fermentation, which can help move waste toward the rectum. However, this is not a primary function of the large intestine. The large intestine does not chemically break down food; this occurs primarily in the stomach and small intestine.
