The bone marrow is the part of the bone that produces blood cells. It contains stem cells that can develop into red blood cells, white blood cells, and platelets.
Bone marrow is the part of the bone responsible for making blood cells. It is a soft, spongy tissue found within the center of bones and is essential for the production of red blood cells, white blood cells, and platelets.
Red marrow produces red blood cells (RBCs), white blood cells (WBCs) and cell fragments called platelets. RBCs carry oxygen through out the body, WBCs fight off infections by bacteria and viruses, other "invaders" and platelets are necessary for blood clotting.
Red blood cells because that is what carries oxygen throughout the body
