APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.

Detailed explanation-2: -Healthy bone marrow releases blood cells into the bloodstream when they are mature and when required. Without bone marrow, our bodies could not produce the white cells we need to fight infection, the red blood cells we need to carry oxygen, and the platelets we need to stop bleeding.

Detailed explanation-3: -Healthy bone requires a substantial blood flow to supply the requisite oxygen and nutrients, and to eliminate carbon dioxide, acid and other metabolic waste products. Estimates of the proportion of the cardiac output received directly by the skeleton range from about 5.5% to 11% (13–15).

Detailed explanation-4: -Production of blood cells In adults, blood cells are mainly produced in the bone marrow. The various blood cells develop in several stages from stem cells to blood cells or blood platelets. White blood cells such as lymphocytes don’t only mature in the bone marrow, but also in the lymph nodes.
