Detailed explanation-1: -The formation of blood cell takes place in the bone marrow. This bone marrow is present in the bones, which are part of the skeletal system.
Detailed explanation-2: -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-3: -Although bones are very hard organs, they also have a dense network of blood vessels inside them where the bone marrow is located as well as on the outside that is covered by the periosteum. This is why bone fractures often cause serious bleeding.
