INFERIOR MESENTERIC ARTERIES Meaning and
Definition
-
The inferior mesenteric arteries refer to a pair of major blood vessels within the human body that arise from the abdominal aorta, specifically the lower segment of this vessel. These arteries play a crucial role in the circulatory system by supplying oxygenated blood to various organs and structures located in the lower abdominal region.
The inferior mesenteric arteries are responsible for delivering blood to the descending colon, sigmoid colon, and rectum. They arise from the abdominal aorta slightly below the level of the renal arteries, which supply the kidneys. After emerging from the aorta, each inferior mesenteric artery courses downwards towards the pelvis, where it eventually divides into multiple smaller branches.
These branches, known as sigmoid arteries, supply blood to the sigmoid colon, which is the final segment of the large intestine before the rectum. Furthermore, the inferior mesenteric arteries also give off left colic arteries, which distribute blood to the descending colon, and superior rectal arteries, which deliver blood to the rectum.
The blood flow provided by the inferior mesenteric arteries is vital for maintaining a healthy functioning digestive system. Any disruption or obstruction of these arteries can lead to various clinical conditions, such as ischemic colitis, where the blood supply to the colon is compromised. Procedures like angioplasty or surgical interventions may be used to manage and restore blood flow in cases of inferior mesenteric artery blockage or stenosis.
