'''Rectal Vein'''

[[File:Gray1082.png|thumb|right|200px|Illustration of the rectal veins from Gray's Anatomy]]

The '''Rectal Vein''' is a part of the [[human circulatory system]] that drains blood from the [[rectum]], a part of the [[digestive system]]. It is a significant component of the [[portal venous system]], which carries blood from the gastrointestinal tract and spleen to the [[liver]].

==Anatomy==

The rectal vein is divided into three main veins: the superior, middle, and inferior rectal veins.

* The '''Superior Rectal Vein''' is the continuation of the [[inferior mesenteric vein]], and it drains into the [[portal vein]].
* The '''Middle Rectal Vein''' drains into the [[internal iliac vein]].
* The '''Inferior Rectal Vein''' drains into the [[internal pudendal vein]], which is a branch of the internal iliac vein.

==Clinical Significance==

The rectal veins are clinically significant as they can be involved in the development of [[hemorrhoids]], a common condition characterized by swollen and inflamed veins in the rectum and anus.
