The purpose of the Rectosigmoid Junction is to serve as a transition zone, that is marked by a change in the lumen's direction and caliber.
The Rectosigmoid Junction also plays a crucial role in your digestive physiology and the process of defecation.
Your Rectosigmoid Junction is also a high pressure zone that acts as a functional sphincter and regulates the movement of fecal matter or poop between your sigmoid colon and your rectum.
The Rectosigmoid junction is on the left side and marks the point where your sigmoid colon connects to your rectum and is also considered to be part of the left side of your colon.
Your Rectosigmoid colon is on the left side of your abdomen.
The sigmoid colon is the last part of your colon and is located in the left lower quadrant of your abdomen.
Your sigmoid colon or rectosigmoid colon is between the descending colon and your rectum and near your uterus or bladder and is about 30 cm long and has an S shape to it.
Your rectum is part of your rectosigmoid colon.
The colon is also divided into the right and left sides, and the transverse colon is in between.
Your right side contains the ascending colon, cecum and hepatic flexure.
Your left side contains your splenic flexure, sigmoid colon, rectum, rectosigmoid and descending colon.
The rectosigmoid junction is located as far up as the level of your third sacral vertebra or the sacral promontory.
The adult human rectum is around 4.7 inches long and begins at your rectosigmoid junction which is the end of your sigmoid colon.
The Rectosigmoid Junction is supplied by the Sigmoidea ima artery, the inferior mesenteric artery and the marginal artery of Drummond.
The sigmoidea ima artery is the lowest sigmoid artery, which connects with the superior rectal artery and forms the distal end of the marginal artery.
The inferior mesenteric artery is what supplies the colon from your distal transverse colon to your rectosigmoid junction.
And the marginal artery of Drummond is an arterial channel which supplies your entire large intestine from your ileocecal junction to your rectosigmoid junction.
The Rectosigmoid is what serves as a storage area where stool or poop water is further recovered through absorption.
The contraction and emptying of your descending colon and rectosigmoid are stimulated by eating.
And in your rectum, your pelvic floor muscles (levator ani, puborectalis) regulate fecal retention and defecation.
The Rectosigmoid Junction is the area of your large intestine where your sigmoid colon and your rectum meet.
The rectosigmoid junction is located between the sacral promontory and the lower margin of your second sacral vertebra.
Your rectosigmoid junction guards against descending colon contents that pass directly to your rectum.
The rectosigmoid junction is a high pressure location which connects different muscles, neurological systems and vascular anastomosis.
