Arteria lienalis

Arteria Lienalis or the Splenic Artery is a major blood vessel that supplies oxygenated blood to the spleen. It is a branch of the Celiac Trunk, which is one of the three major branches of the Abdominal Aorta.

Anatomy

The Arteria Lienalis originates from the Celiac Trunk, which is located in the upper part of the abdominal aorta. It follows a tortuous course towards the Spleen, giving off several branches along its path. These branches include the Pancreatic Branches which supply the pancreas, and the Short Gastric Arteries which supply the upper part of the stomach.

Function

The primary function of the Arteria Lienalis is to supply oxygenated blood to the spleen. The spleen plays a crucial role in the body's immune system, filtering blood and producing white blood cells. The Arteria Lienalis ensures that the spleen receives a constant supply of oxygen and nutrients to perform these functions.

Clinical Significance

Damage or disease affecting the Arteria Lienalis can have serious consequences. For example, a Splenic Artery Aneurysm is a condition where the wall of the artery weakens and bulges out. This can potentially rupture, leading to internal bleeding and requiring emergency medical attention.
