What is "bone marrow"?

Bone marrow is a soft, spongy tissue found within certain bones, primarily in the center of long bones and the cavities of flat bones. It is responsible for the production and development of blood cells, including red blood cells, white blood cells, and platelets. Bone marrow contains stem cells, which differentiate and mature into specialized blood cells to support various bodily functions, such as oxygen transport, immune response, and blood clotting. Additionally, bone marrow serves as a storage site for fat cells and plays a role in the body's immune system. Disorders affecting bone marrow can impact blood cell production and overall health, making it a crucial component of the body's hematopoietic system.
