APPLIED RADIOLOGICAL ANATOMY

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.

Detailed explanation-2: -Where are blood cells made? 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.

Detailed explanation-3: -The human bone marrow is one of the body’s largest organs occupying the central regions of virtually all long and flat bones. Consisting of a mixture of fat and hematopoietic precursor, the marrow typically produces 500 billion mature blood cells daily (Fliedner et al., 2002).

Detailed explanation-4: -In adult humans, bone marrow is primarily located in the ribs, vertebrae, sternum, and bones of the pelvis. Bone marrow comprises approximately 5% of total body mass in healthy adult humans, such that a man weighing 73 kg (161 lbs) will have around 3.7 kg (8 lbs) of bone marrow.
