Structure of the spleen
After going through this study, you will be able to:
- Describe the location of the spleen and its relations with nearby organs.
- Identify the parts and landmarks of the spleen.
- Get familiar with the structure and main functions of this organ.
The spleen is a soft, delicate, fist-sized, intraperitoneal organ covered by a fibroelastic capsule. It is located in the left upper quadrant of the abdomen (left hypochondrium), at the level of the 9th to 11th ribs, posterior to the stomach and anterior to the left hemidiaphragm and costodiaphragmatic recess. It plays an important role in the immune system, by participating both in the humeral and the cell-mediated responses.
After watching the following video you will learn everything you should know about the anatomy of the spleen, its internal structure, relations and neurovasculature.
