ANATOMY

Detailed explanation-1: -The large intestine’s main job is to remove water from the undigested matter and form solid waste (poop) to be excreted. The large intestine has three parts: The cecum (pronounced: SEE-kum) is the beginning of the large intestine. The appendix, a small, hollow, finger-like pouch, hangs at the end of the cecum.

Detailed explanation-2: -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-3: -Your large intestine is the final part of your digestive tract. Undigested food enters your large intestine from your small intestine. It then reabsorbs water that is used in digestion and eliminates undigested food and fibre. This causes food waste products to harden and form faeces, which are then excreted.

Detailed explanation-4: -The colon removes water and some nutrients and electrolytes from partially digested food. The remaining material, solid waste called stool, moves through the colon, is stored in the rectum, and leaves the body through the anus.

Detailed explanation-5: -Egestion – the removal of undigested food materials.
