What is the function of the ascending transverse 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.
What is the function of the transverse colon in the digestive system?
The transverse colon runs across the abdomen. The descending colon travels down the left abdomen. The sigmoid colon is a short curving of the colon, just before the rectum. The colon removes water, salt, and some nutrients forming stool.
What is descending colon and its function?
The descending colon is a section of the large intestine. It is the left part of the colon that passes downward. It is responsible for storing the remains of digested food before they pass through the rest of the colon and rectum for elimination. The large intestine plays a role in the absorption of nutrients.
What is a ascending colon definition?
The ascending colon is located on the right side of the abdomen. It receives the digesting food from the small intestine. At its start, it is connected to the cecum, which is the first part of the large intestine.
What is the ascending and descending colon?
It runs from the small intestine to the rectum. It is made up of three portions; the ascending, transverse and descending colon. The ascending colon is sometimes referred to as the right colon; the descending colon is sometimes referred to as the left, or sigmoid colon.
Where is the ascending colon located?
The ascending colon lies on the right side of the abdominal cavity, in front of the quadratus lumborum and transversus abdominis muscle. It extends from the cecum to the hepatic flexure and averages 12 to 20 cm in length.
Where is the ascending intestine?
Is ascending colon retroperitoneal?
The appendix, transverse colon, and sigmoid colon have a mesentery (called mesoappendix, transverse mesocolon and sigmoid mesocolon, respectively), but the ascending colon and descending colon and the rectum and anal canal are retroperitoneal; the cecum does not have its own mesentery but is covered in all aspects by …
What’s the ascending colon?
The ascending colon is a hollow tube about 2.5 inches in diameter and about 8 inches long, with many small pouches along its length to increase its surface area. The inferior end of the ascending colon connects to the cecum of the large intestine in the right iliac region of the abdominal cavity.
Why is the ascending colon retroperitoneal?
All portions of the fetal colon are suspended on mesenteries, but the mesenteries of the ascending and descending colon usually fuse to the retroperitoneal fascia, normally leaving these portions covered by peritoneum only on their anterior surface and are thus regarded as retroperitoneal organs.
What nutrients are absorbed in the ascending colon?
As the feces pass through the ascending colon, bacteria digest the waste material that the human body cannot digest and liberate vitamins K, B1, B2, and B12. The walls of the colon absorb these vitamins along with most of the water present in the feces.
Is the ascending colon intraperitoneal or retroperitoneal?
retroperitoneal
The ascending colon measures 10 to 20 cm and lies within the anterior pararenal space. The ascending colon is a retroperitoneal structure covered only on its ventral and lateral surfaces by the posterior peritoneum.
