Are there white blood cells in 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.
Are white blood cells destroyed in the spleen?
Blood cells that can’t pass the test will be broken down in your spleen by macrophages. Macrophages are large white blood cells that specialize in destroying these unhealthy red blood cells. Always economical, your spleen saves any useful components from the old cells, such as iron.
What white blood cell makes antibodies in the spleen?
Adaptive immune cell function and organization B-2, follicular B cells are the canonical T-dependent antibody-producing B cells in the spleen (61).
What immune cells are in the spleen?
Spleen houses tolerogenic immune cells like CD8+ Treg cells, F4/80+ macrophages, CD68+F4/80+ red pulp macrophages, CD169+ metallophillic macrophages, CD8+CD205+ splenic dendritic cells (DCs), splenic CD8α+CD103+CD207+ DCs, CD43+veCD19hiCD5+veIgMhiIgDlo B cells, and splenic NKT cells that express regulated on activation …
What do B cells do in the spleen?
The functions of splenic B cells are considered. Antibody production, cytokine synthesis, and potential immunoregulatory activities are considered.
What is the function of white pulp in the spleen?
Both white and red pulp contains lymphocytes and immune cells called macrophages. These cells dispose of antigens, dead cells, and debris by engulfing and digesting them. While the spleen functions chiefly to filter blood, it also stores red blood cells and platelets.
What are the signs of a damaged spleen?

What kind of tissue is in the spleen?
The types of tissue in the spleen are: White pulp: As part of the immune system, the white pulp produces white blood cells. These blood cells make antibodies. Antibodies fight infection. Red pulp: The red pulp acts like a filter. It removes waste from the blood and gets rid of old or damaged blood cells.
How is the spleen important to the immune system?
It holds key components of the body’s immune system. The spleen also removes unhealthy, old, and misshapen red blood cells from circulation. Red blood cells carry oxygen throughout the body and remove carbon dioxide (a waste product). These disc-shaped cells are filtered by the spleen based on their physical characteristics.
Where does the iron from the spleen go?
Macrophages are large white blood cells that specialize in destroying these unhealthy red blood cells. Always economical, your spleen saves any useful components from the old cells, such as iron. It stores iron in the form of ferritin or bilirubin, and eventually returns the iron to your bone marrow, where hemoglobin is made.
