What are the 4 functions of the spleen?
Function
- Stores blood.
- Filters blood by removing cellular waste and getting rid of old or damaged blood cells.
- Makes white blood cells and antibodies that help you fight infection.
- Maintains the levels of fluid in your body.
- Produces antibodies that protect you against infection.
How does the spleen filter red blood cells?
Blood passes through the cords and into the sinusoids where it is drained into the large trabecular veins of the spleen. Blood is filtered through gaps in the sinusoid lining, which prevents old, damaged or abnormal red blood cells from passing into the bloodstream.
Does the spleen produce red blood cells?
The spleen clears out old platelets from the blood; it also acts as a reservoir for platelets. As a fetus is developing, the spleen makes red blood cells, but after the fifth month of gestation, it stops. The spleen also produces compounds called opsonins, such as properdin and tuftsin, that help the immune system.
What are the function of the spleen?
The spleen has some important functions: it fights invading germs in the blood (the spleen contains infection-fighting white blood cells) it controls the level of blood cells (white blood cells, red blood cells and platelets) it filters the blood and removes any old or damaged red blood cells.
What’s the function of the spleen?

Does the spleen store red blood cells?
The spleen also stores red blood cells, platelets, and infection-fighting white blood cells. The spleen plays an important role in your immune system response. When it detects bacteria, viruses, or other germs in your blood, it produces white blood cells, called lymphocytes, to fight off these infections.
Does spleen contain macrophages?

Does the spleen produce T cells?

How many red blood cells are stored in the spleen?
Storage of red blood cells, lymphocytes and other formed elements. The spleen of horses stores roughly 30% of the red blood cells and can release them when needed. In humans, up to a cup (240 ml) of red blood cells is held in the spleen and released in cases of hypovolemia and hypoxia.
What is the function of the white pulp in the spleen?
The spleen contains two different tissues, white pulp (A) and red pulp (B). The white pulp functions in producing and growing immune and blood cells. The red pulp functions in filtering blood of antigens, microorganisms, and defective or worn-out red blood cells. Mechanical filtration of red blood cells.
