The spleen of horses stores roughly 30 percent of the red blood cells and can release them when needed. [20] In humans, up to a cup (240 ml) of red blood cells is held within the spleen and released in cases of hypovolemia [21] and hypoxia. [22] It can store platelets in case of an emergency and also clears old platelets from the circulation.
A splenocyte is a white blood cell that resides in the spleen and are involved in functions of the spleen, like filtering blood and the immune response. [1]Splenocytes consist of a variety of cell populations such as T and B lymphocytes, dendritic cells and macrophages, which have different immune functions.
The cells chant for the heart to work again except for a veteran red blood cell who is tired of working. The heart is shocked by a defibrillator and works again. The coronary artery gets a stent inserted to clear the blockage, allowing the blood to circulate again. The red blood cells deliver oxygen to all the body's cells, saving them.
The T cell zone (periarteriolar sheath) and B cell follicles contain discrete macrophage populations; however, not much is known about these macrophage populations in terms of their origin and lifespan. These macrophages are not unique to the spleen but instead make up an integral part of the lymphoid parts of all secondary lymphoid organs.
Gaps in the endothelium lining the sinusoids mechanically filter blood cells as they enter the spleen. Worn-out or abnormal red cells attempting to squeeze through the narrow intercellular spaces become badly damaged, and are subsequently devoured by macrophages in the red pulp. [ 6 ]
The cells are primarily monocytes and macrophages, and they accumulate in lymph nodes and the spleen. The Kupffer cells of the liver and tissue histiocytes are also part of the MPS. The mononuclear phagocyte system and the monocyte macrophage system refer to two different entities, often mistakenly understood as one.

Cells at Work! (Japanese: はたらく細胞, Hepburn: Hataraku Saibō) is a Japanese manga series written and illustrated by Akane Shimizu.It features the anthropomorphized cells of a human body, with the two main protagonists being a red blood cell and a white blood cell she frequently encounters.
