Water is absorbed in the intestine through which of the following processes? a. Facilitated transport b. Simple diffusion c. Active transport d. Active diffusion

Water is primarily absorbed in the intestine through simple diffusion, where it moves across the intestinal cell membranes from an area of higher concentration to an area of lower concentration, effectively balancing the concentration gradient. This passive process is vital for maintaining hydration and electrolyte balance in the body. In addition to simple diffusion, facilitated transport also plays a role in water absorption, particularly through specialized channels called aquaporins. These channels help speed up the movement of water when the body needs to absorb it rapidly, ensuring efficient hydration during digestion and absorption!
