What term represents the three categories of blood cells: erythrocytes, leucocytes, and thrombocytes?

Explanation:
Formed elements are the solid components of blood, including red blood cells (erythrocytes), white blood cells (leucocytes), and platelets (thrombocytes). This term is used to describe all the cellular parts of blood together, contrasted with plasma, the liquid portion. So the three categories are encompassed under formed elements, which is why it’s the best label. Describing them as “3 Types of blood Cells” is descriptive but not the standard formal term, and “Blood Cells” is too general, while “Plasma Proteins” are not cells at all.
