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: -Erythropoiesis is red blood cell (erythrocyte) production. Your bone marrow makes most of your red blood cells. Once they’re fully mature, they’re released into your bloodstream, where they transport oxygen throughout your body.

Detailed explanation-3: -White blood cells are produced by bone marrow and their levels of production are regulated by organs such as the spleen, liver, and kidneys. Granulocytes and agranulocytes are the two types of white blood cells or leukocytes. Granulocytes contain granules or sacs in their cytoplasm and agranulocytes do not.

Detailed explanation-4: -Where are blood cells made? Blood cells are made in the bone marrow. The bone marrow is the soft, spongy material in the center of the bones.

Detailed explanation-5: -Red bone marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow bone marrow is made mostly of fat and contains stem cells that can become cartilage, fat, or bone cells.
