MESENTERIC CIRCULATIONS Meaning and
Definition
-
Mesenteric circulations refer to the network of blood vessels responsible for delivering oxygenated blood to the intestine and its surrounding structures in the abdomen. The term specifically pertains to the two main blood supplies in this region: the superior mesenteric artery (SMA) and the inferior mesenteric artery (IMA).
The superior mesenteric artery originates from the abdominal aorta and branches out to supply the small intestine, ascending colon, and parts of the transverse colon. It provides oxygenated blood rich in nutrients to support the digestive processes in these areas. The superior mesenteric vein carries the deoxygenated blood, waste products, and nutrients away from the intestine and drains it into the hepatic portal system, ultimately leading to the liver.
On the other hand, the inferior mesenteric artery arises from the abdominal aorta just above the bifurcation and supplies blood to the distal parts of the transverse colon, descending colon, sigmoid colon, and rectum. The inferior mesenteric vein collects the deoxygenated blood and transports it towards the hepatic portal vein.
The mesenteric circulations are crucial for maintaining the normal functioning of the digestive system by ensuring an adequate blood supply to the intestines, primarily for absorption of nutrients and removal of waste products. Any disruption or impairment of blood flow in these circulations can result in various medical conditions, such as mesenteric ischemia, bowel obstruction, and colonic ischemia, which can lead to severe abdominal pain, tissue damage, and potentially life-threatening consequences.

Etymology of MESENTERIC CIRCULATIONS
The etymology of the word "mesenteric" comes from the combination of two Greek words: "mesos" meaning "middle" or "in the middle" and "enteron" meaning "intestine". The term "mesenteric" thus refers to the middle or central part of the intestine.
The word "circulations" has Latin roots and derives from the Latin word "circulare", which means "to circulate" or "to move in a circular manner". In the context of "mesenteric circulations", it refers to the movement or flow of blood through the blood vessels in the mesentery, the double layer of peritoneum that attaches the intestine to the abdominal wall.
Therefore, "mesenteric circulations" refers to the blood flow within the blood vessels of the mesentery, which supplies and nourishes the intestines.
