How the Body Works The Spleen

The spleen is a small organ located behind the stomach in the left, upper part of the abdomen. A mass of lymphoid tissue, it contains two distinct areas, the white pulp and the red pulp. The white pulp is distributed, as tiny nodules of lymphatic tissue, among the red pulp, which fills all the remaining space. The white pulp is responsible for the production of lymphocytes. Some lymphocytes enter the blood, while others remain in the spleen, where they ingest and destroy foreign or damaged cells. The red pulp contains many blood channels, expanded capillary lakes, which act as filters when blood is forced through them, removing damaged or abnormal red cells and allowing normal ones to pass through. The lymphocytes then engulf and destroy these damaged red cells. The spleen also acts as a store for red blood cells.

They are no the same thing. WBCs are Called leukocytes and are useful in bacterial infections. Lymphocytes are responsible for battling Viral and fungal infections. Macrophages are part of the Monnonuclear phagocytic system which removes debris such as old RBCs from the Spleen and reticular connective tissue. Macrophages are also in the liver and respiratory tract.

@oriondimension lymphocytes = white blood cells = macrophages

they are relatively the same thing.

[oriondimension]

At 0:48, lymphocytes do not engulf damaged cells, that's macrophages' job.

But nice work though :)

Basically, its purpose is to get red of the old red blood cells and recycle the heme to produce new fresh red blood cells that are more efficient. Further, it is the largest lymphatic tissue in the body...meaning it has a role in immunity. It eats up bacteria, parasites, and debris that is in the blood system.. and send antibodies out once it detects antigens (infectious agents) in the blood. Keep in mind, the spleen is not a vital organ (do not need to live) -Other organscantake its function
