Ans: C, D, E
Feedback: The small intestine is the longest segment of the GI tract, accounting for about two-thirds of the total length. It folds back and forth on itself, providing approximately 7000 cm (70 m) of surface area for secretion and absorption, the process by which nutrients enter the bloodstream through the intestinal walls. The colon makes the stool that is human waste. The small intestine does not reabsorb water to maintain blood pressure, the kidneys do.
