What is the function of the ascending and descending colon?
the ascending colon, which absorbs the remaining water and other nutrients from the indigestible food material, solidifying it into stool the transverse colon, which absorbs water and salts from the indigestible material the descending colon, which is a storage area for feces sigmoid colon, which moves stool into the rectum
What is the function of the transverse colon?
As the longest and most mobile part of the colon, the transverse colon plays an essential role in digestion and the excretion of waste products. It also helps absorb water from digested food, making it easier for waste products to move through the body. Many conditions can affect this part of the digestive tract, including:

Gross Anatomy. From the cecum, the ascending colon rises superiorly toward the right inferior border of the liver. Just before reaching the liver, the ascending colon turns about 90 degrees to the left at the hepatic flexure. From the hepatic flexure the colon continues onward as the transverse colon.
