The SMV vein, or superior mesenteric vein, is a major blood vessel in the abdomen. Specifically, it's a large venous tributary that plays a crucial role in draining blood from the majority of the abdominal organs.
Details About the Superior Mesenteric Vein
- Function: Drains blood from most abdominal organs. According to the reference, it "serves to drain the vast majority of the organs of the abdominal cavity".
- Origin: Embryologically, it develops in association with the vitelline vein.
- Location: The superior mesenteric vein lies lateral to the superior mesenteric artery (SMA).
- Significance: It's a major component of the venous system in the abdomen, responsible for returning blood to the heart after it has circulated through the digestive organs.
In summary, the SMV vein is a critical vessel for abdominal venous drainage, located near the superior mesenteric artery and developing alongside the vitelline vein.
