Answer
9. Three functions of the large intestine:* **Absorption of water and electrolytes:** The large intestine reclaims water from the undigested food material, solidifying it into feces. It also absorbs important electrolytes like sodium and potassium.* **Production and absorption of vitamins:** Bacteria residing in the large intestine produce certain vitamins, particularly vitamin K and some B vitamins. These are then absorbed into the bloodstream.* **Formation and elimination of feces:** The large intestine compacts the remaining waste material into feces and stores it until it can be eliminated from the body through defecation.10. Four divisions of the colon:* **Ascending colon:** The first section, traveling upwards on the right side of the abdomen.* **Transverse colon:** The section that runs horizontally across the upper abdomen.* **Descending colon:** The section that travels downwards on the left side of the abdomen.* **Sigmoid colon:** The S-shaped final section of the colon, leading into the rectum.
