Which term best describes the cellular components of blood, including erythrocytes, leukocytes, and platelets?

Explanation:
Blood has two main parts: a liquid portion called plasma and a cellular portion called formed elements. Erythrocytes, leukocytes, and platelets are the cellular components, so they are described as formed elements. Plasma contains the fluid and dissolved substances, including clotting factors; serum is plasma minus those clotting factors, obtained after blood clots. The buffy coat is the thin layer, seen after centrifugation, that contains leukocytes and platelets. So the best term for the cellular components is formed elements.
