What is blood bank of your body?

Spleen is often called as the blood bank or graveyard of the red blood cells.

Actually, the spleen acts as the blood bank for the body in the following ways:

1. Storage of red blood cells: The spleen stores a significant amount of red blood cells, which can be released into the bloodstream when needed. This can help to increase oxygen delivery to tissues during periods of increased demand, such as during exercise or stress.

2. Removal of old or damaged red blood cells: The spleen also acts as a filter for red blood cells, removing old or damaged cells from the circulation. This helps to maintain the quality of the blood supply and prevent the buildup of harmful substances in the body.

3. Immune function: In addition to its role in storing and filtering red blood cells, the spleen also plays an important role in the body's immune system. It contains a large number of immune cells, such as macrophages and lymphocytes, which help to identify and destroy foreign invaders, such as bacteria and viruses.
