The formed elements in the blood are typically known as cellular components of blood, which include red blood cells, white blood cells, and platelets. While plasma and serum are important components of the blood, they are not considered formed elements as they are liquid portions that do not contain cellular material. Blood cells are also a broad term, whereas the terminology "formed elements" specifies the three types of cells mentioned above. Therefore, the formed elements in the blood are specifically referred to as peripheral blood.
