Plasma cells are a group of white blood cells produced by the body to fight infection.
The function of the plasma cell is to make antibodies which are proteins that attack and destroy invading organisms. The antibodies make the organisms more visibile to other white cells or may rupture the organism altogether. To understand MM, it is first important to understand the function of the bone marrow and its role in the production of blood cells. In our bloodstream, there are three kinds of blood cells, namely, red cells, white cells, and platelets. Red blood cells contain haemoglobin for carrying oxygen to our tissues.
