In the villi of the small intestine, water is absorbed into the:
A)capillary networks by active transport
B)lacteals in combination with bile salts
C)capillary networks by osmosis
D)lacteals by active transport

Question

Quizplus · Accepted Answer

Water is absorbed by osmosis from the small intestine villi into the capillary networks. This occurs due to the high concentration of solutes in the intestinal lumen, which creates a gradient that draws water out of the villi and into the capillaries. Active transport is not involved in water absorption in the small intestine, and bile salts are involved in the absorption of fats, not water. Lacteals also play a role in fat absorption, but not water absorption.
