The absorption of water in the small intestine depends on the absorption of what else?

Water is absorbed by osmosis and lipids by passive diffusion throughout the small intestine.

Explanation:In the colon endocrine mechanisms used include: Aldosterone – increases the net absorption of water and electrolytes by stimulating the basolateral sodium-potassium ATP-ase. This increases the electrochemical gradient and driving force for sodium absorption.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
