ANATOMY

Detailed explanation-1: -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-2: -Red blood cell (RBC) production (erythropoiesis) takes place in the bone marrow under the control of the hormone erythropoietin (EPO). Juxtaglomerular cells in the kidney produce erythropoietin in response to decreased oxygen delivery (as in anemia or hypoxia) or increased levels of androgens.

Detailed explanation-3: -Produces blood cells: Bones contain bone marrow. Red and white blood cells are produced in the bone marrow. Protects and supports organs: Your skull shields your brain, your ribs protect your heart and lungs, and your backbone protects your spine.

Detailed explanation-4: -Most of the white blood cells are produced by the skeletal system. Both red and white blood cells, as well as platelets, are formed in the bone marrow, the soft inner part of the bones.

Detailed explanation-5: -Bone marrow is part of the skeletal system. Red bone marrow is primarily found within flat bones of the body, which include the ribs, sternum, skull, and shoulder blades.
