Detailed explanation-1: -Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum.
Detailed explanation-2: -The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over.
Detailed explanation-3: -Water is absorbed by the large intestine by osmosis, with diffusion occurring in accordance with the osmotic gradient. Sodium is absorbed by the sodium/potassium pump in the colon, which diffuses potassium and sodium in opposite directions due to the formation of concentration gradients.
Detailed explanation-4: -The large intestine (colon) also absorbs some water. Nearly all the water is absorbed into the bloodstream from the small intestine. The excess fluid absorbed in the blood is filtered by the kidneys, which produce the urine that is transported to the bladder.
Detailed explanation-5: -Absorption of Water and Electrolytes The large intestine functions to absorb any excess water from the material it receives from the small intestine.
