Active transport of ______ from the lumen of the intestine into the cells lining the intestine facilitates absorption of water from the gastrointestinal tract.

Question

Quizplus · Accepted Answer

Sodium is actively transported from the lumen of the intestine into the cells lining the intestine, which creates a concentration gradient that allows for water to passively diffuse into the cells and then into the bloodstream. This process is known as osmosis and facilitates the absorption of water from the gastrointestinal tract. Amino acids and glucose are also actively transported, but they do not directly facilitate the absorption of water. Phosphorus is primarily absorbed passively, not through active transport.
