Detailed explanation-1: -Thrombocytes, or platelets, are not complete cells, but are small fragments of very large cells called megakaryocytes. Megakaryocytes develop from hemocytoblasts in the red bone marrow. Thrombocytes become sticky and clump together to form platelet plugs that close breaks and tears in blood vessels.

Detailed explanation-2: -The cellular elements-referred to as the formed elements-include red blood cells (RBCs), white blood cells (WBCs), and cell fragments called platelets.

Detailed explanation-3: -Platelets, or thrombocytes, are small, colorless cell fragments in our blood that form clots and stop or prevent bleeding.

Detailed explanation-4: -The platelets, which are small cellular fragments rather than complete cells, are formed from bits of the cytoplasm of the giant cells (megakaryocytes) of the bone marrow.
