Understanding Blood Production and the Skeletal System

Blood is produced in the bone marrow located in the large bones of the skeletal system. The marrow contains capillaries that allow new blood cells to enter the circulatory system. The skeletal system consists of bones, joints, and connective tissues like cartilage, which support the body. Cartilage, a flexible tissue, is found where bones meet and acts as a shock absorber, such as between the vertebrae of the spine.
