Water is absorbed in the gastrointestinal tract by:

Question

Quizplus · Accepted Answer

Water is mainly absorbed in the gastrointestinal tract by osmosis, which is the passive movement of water across a semi-permeable membrane from areas of low solute concentration to areas of high solute concentration. This allows for the movement of water from the lumen of the gut into the bloodstream, where it can be carried to the rest of the body. Active transport and endocytosis are not involved in the absorption of water in the gastrointestinal tract, and Brownian motion refers to the random movement of particles in a fluid and is not a mechanism of absorption.
