GENERAL HISTOLOGY

Detailed explanation-1: -Spongy bone is found mostly at the ends of bones and contains red marrow. Bone marrow is found in the center of most bones and has many blood vessels. There are two types of bone marrow: red and yellow. Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets.

Detailed explanation-2: -Most blood cells are made in your bone marrow. This process is called haemopoiesis. In children, haemopoiesis takes place in the long bones, like the thighbone (femur). In adults, it’s mostly in the spine (vertebrae) and hips, ribs, skull and breastbone (sternum).

Detailed explanation-3: -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-4: -Red marrow is found mainly in the flat bones, such as the hip bone, sternum (breast) bone, skull, ribs, vertebrae, and shoulder blades, as well as in the metaphyseal and epiphyseal ends of the long bones, such as the femur, tibia, and humerus, where the bone is cancellous or spongy.

Detailed explanation-5: -Where does hematopoiesis occur? The most common site of blood cell production is the spongy tissue inside of your bones called bone marrow. Hematopoiesis that occurs in your bone marrow is called medullary hematopoiesis. Blood cells get made in your bone marrow and released into your bloodstream.
