Arteria lienis, also known as the splenic artery, is an essential blood vessel responsible for supplying the spleen with blood. It is a branch of the celiac artery and runs along the posterior side of the pancreas before branching off to reach the spleen. The splenic artery also forms connections with other blood vessels, such as the left gastro-omental artery and the short gastric arteries. Despite its important role in the body, there are few synonyms for the term "arteria lienis." Some possible alternatives include "splenic artery" or "arterial supply to the spleen." Nonetheless, regardless of the term used, this artery plays a crucial role in maintaining proper functioning of the spleen and overall health.
