People donate bone marrow so that those in need can produce C. Blood and Fat.

Bone marrow is a soft, spongy tissue found inside our bones. It is responsible for producing different types of blood cells, including red blood cells, white blood cells, and platelets. Additionally, bone marrow contains a small amount of fat.

When individuals donate bone marrow, they are providing a source of healthy stem cells that can be transplanted into a recipient. These stem cells have the ability to develop into mature blood cells, helping those in need who may have certain blood disorders, such as leukemia or aplastic anemia. The donated bone marrow replenishes the recipient's supply of healthy blood cells and also aids in the production of new fat cells.

In summary, bone marrow donation helps those in need produce blood cells, including red blood cells, white blood cells, and platelets, as well as replenishing their fat cells.
