Detailed explanation-1: -Red bone marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow bone marrow is made mostly of fat and contains stem cells that can become cartilage, fat, or bone cells. Anatomy of the bone.

Detailed explanation-2: -Blood cells are made in the bone marrow. The bone marrow is the soft, spongy material in the center of the bones. It produces about 95% of the body’s blood cells. Most of the adult body’s bone marrow is in the pelvic bones, breast bone, and the bones of the spine.

Detailed explanation-3: -Inside the bone marrow, blood stem cells divide and mature to make new blood cells. During this process, the cells become either lymphocytes (a kind of white blood cell) or other blood-forming cells. These other blood-forming cells mature into red blood cells, white blood cells (other than lymphocytes), or platelets.

Detailed explanation-4: -Most red blood cells, platelets, and most white blood cells form in the red bone marrow. Yellow bone marrow produces fat, cartilage, and bone. White blood cells survive from a few hours to a few days, platelets for about 10 days, and red blood cells for about 120 days.
