What are the formed elements of blood?
The formed elements are cells, cell remnants, and cell fragments in the blood. Red Blood Cells (RBCs or erythrocytes) make up more than 95% of the formed elements. A red blood cell in a section of capillary. Because they lack a nucleus and organelles, most RBCs in the bloodstream are not fully functional cells.

red bone marrow 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.
