Document Summary
Shaped like a lymph node (large) bean shape. Has hilum: blood vessels are supplying the spleen. Image is artery going into spleen: huge blood vessel: important because of the function of the spleen. Spleen: filters blood (makes sense that we have large artery / large vein that supplies blood to the spleen and takes blood away from the spleen) Spleen: big bag of blood not much structure but highly vascularized. Interstitial fluid that makes up lymph drains out of the spleen via efferent lymphatic vessel. Unlike lymph node, there is not an outer cortex and inner medulla. Spleen has red pulp and white pulp intermixed with one another: red pulp: role in rbc recycling but located throughout. Nodules are located in the spleen and referred to as splenic nodules. Like lymphatic nodules, they are collections of b cells in the germinal center that differentiate. Has a capsule like the lymph node.
