The spleen is innervated by the splenic plexus, which connects a branch of the celiac ganglia to the vagus nerve. The underlying central nervous processes coordinating the spleen's function seem to be embedded into the hypothalamic-pituitary-adrenal-axis, and the brainstem, especially the subfornical organ. [17]
In human anatomy, the splenic artery or lienal artery, an older term, is the blood vessel that supplies oxygenated blood to the spleen. It branches from the celiac artery, and follows a course superior to the pancreas. It is known for its tortuous path to the spleen.
An image of the spleen in the human body. Also shows the red and white pulp regions. Splenocytes are spleen cells and consist of leukocytes like B and T cells, dendritic cells, and macrophages. [2] The spleen is split into red and white pulp regions with the marginal zone separating the two areas. The red pulp is involved with filtering blood ...
1905 diagram of the internal organs of human body. In the study of anatomy, viscera (sg.: viscus) refers to the internal organs of the abdominal, thoracic, and pelvic cavities. [5] The abdominal organs may be classified as solid organs or hollow organs. The solid organs are the liver, pancreas, spleen, kidneys, and adrenal glands.
Periarteriolar lymphoid sheaths (or periarterial lymphatic sheaths, or PALS) are a portion of the white pulp of the spleen.They are populated largely by T cells and surround central arteries within the spleen; the PALS T-cells are presented with blood borne antigens via myeloid dendritic cells.

The spleen is the largest lymphoid organ in the body but has other functions. [23] It breaks down both red and white blood cells that are spent. This is why it is sometimes known as the 'graveyard of red blood cells'. [23] A product of this digestion is the pigment bilirubin, which is sent to the liver and secreted in the bile.
The clitoris is the only organ in the human body that exists exclusively for pleasure. Those in the medical community had no reason to assume they were wrong. The anatomical “maps” that anchored their education must have seemed as sturdy and steadfast as Mercator’s, with every organ plotted and every muscle annotated.
