RECTAL VEIN Meaning and
Definition
-
The rectal vein, also known as the hemorrhoidal vein or the superior rectal vein, is a blood vessel that plays a crucial role in the circulatory system of the human body. It is a vein specifically located within the rectum, a portion of the large intestine that connects the colon to the anus.
The rectal vein functions as a major pathway for the transportation of deoxygenated blood from the rectum back to the heart. It is responsible for draining blood from the rectal region and serves as a link between the systemic venous circulation and the portal venous circulation. The rectal vein directly connects with the superior mesenteric vein, forming a critical component of the portal system, which carries absorbed nutrients from the gastrointestinal tract to the liver for processing.
As a part of the venous system, the rectal vein possesses thin walls and contains valves that ensure the unidirectional flow of blood towards the heart. However, the rectal vein can become enlarged or swollen under certain circumstances, leading to a condition known as hemorrhoids. Hemorrhoids are dilated or varicose veins located near the rectum or anus, resulting in discomfort, itchiness, and bleeding.
In summary, the rectal vein is the major venous pathway within the rectum that aids in the return of deoxygenated blood and plays a crucial role in the systemic and portal circulatory systems.
