9. List three (3)functions of the large intestine. 10. Name the four (4) divisions of the colon.

9. Three functions of the large intestine:<br /><br />* **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.<br />* **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.<br />* **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.<br /><br /><br />10. Four divisions of the colon:<br /><br />* **Ascending colon:** The first section, traveling upwards on the right side of the abdomen.<br />* **Transverse colon:** The section that runs horizontally across the upper abdomen.<br />* **Descending colon:** The section that travels downwards on the left side of the abdomen.<br />* **Sigmoid colon:** The S-shaped final section of the colon, leading into the rectum.<br />
