ANATOMY

Detailed explanation-1: -The long, tube-like organ that is connected to the small intestine at one end and the anus at the other. The large intestine has four parts: cecum, colon, rectum, and anal canal. Partly digested food moves through the cecum into the colon, where water and some nutrients and electrolytes are removed.

Detailed explanation-2: -Finger-like projections called villi line the interior wall of the small intestine and absorb most of the nutrients. The remaining chyme and water pass to the large intestine, which completes absorption and eliminates waste.

Detailed explanation-3: -4 large intestine It’s a large tube that soaks up water and minerals and leaves only the waste. Solid waste passes out of your body.

Detailed explanation-4: -Absorption of water occurs by osmosis. Water diffuses in response to an osmotic gradient established by the absorption of electrolytes. Sodium is actively absorbed in the colon by sodium channels.
