define formed elements of blood
Answers. Best Answer: The formed elements of the blood are all the cellular components in the blood. The three major categories correspond to the maturational lineages followed by the immature, pluripotent stem cells in the bone marrow-the erythroid, myeloid and lymphoid lineages. The least numerous formed element is probably the white blood cell called the basophil. There are very few of them seen in a peripheral blood draw. The most numerous are probably the red blood cells or erythrocytes. The buffy coat consists of all the white blood cells in a centrifuged blood sample, such as one has in a hematocrit tube.
