Detailed explanation-1: -The formed elements are cells and cell fragments suspended in the plasma. The three classes of formed elements are the erythrocytes (red blood cells), leukocytes (white blood cells), and the thrombocytes (platelets).
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: -The blood cells are known as the formed elements and consist of the erythrocytes (RBC’s), leukocytes (WBC’s and thrombocytes (platelets). They are formed in the bone marrow by the process of hametopoeisis. So, the correct option is ‘Bone marrow’. Was this answer helpful?
