What is the hilum of the spleen?
It’s covered in visceral peritoneum, a smooth membrane that’s composed of two layers of cells, which secrete fluid and serve a protective function. 1 There is, however, an opening in this membrane called the hilum of the spleen, which allows the splenic artery and vein to circulate blood to the organ.
Why is the microscopic anatomy of the spleen important?
Understanding the microscopic anatomy of the spleen is important for understanding its function. Numerous septa called trabeculae extend from the dense irregular fibroelastic connective tissue of the capsule into the parenchyma of the spleen. Both the capsule and trabeculae contain myoepithelial cells which have the ability to contract.

Why is the spleen considered a graveyard for red blood cells?
One of the most important functions of the spleen is blood filtering. It is considered a “graveyard for red blood cells” because it removes old and damaged erythrocytes from circulation. This function is mostly due to the unique structure of the blood vessels and macrophages present in the red pulp.
How does blood enter the spleen through the hilum?
Blood from the splenic artery enters the spleen through the hilum. From there, the artery divides into smaller branches that enter the splenic parenchyma following the course of trabeculae. Together with the trabeculae, the arteries branch throughout the parenchyma and gradually decrease in diameter.
