What are the three phases of blood following centrifugation

•What are the three phases of blood following centrifugation? What is contained in each?

•What are the formed elements of blood?

•What stimulates RBC synthesis?

•What are the two primary categories of WBCs?

•How do platelets contribute to homeostasis?

Solution

1.The three phases of blood during centrifugation are

2.\"formed elements\" consist of erythrocytes (red blood cells, RBCs), leukocytes (white blood cells), and thrombocytes (platelets).

3.Erythropoesis is stimulated by decreased O₂ in circulation, which is detected by the kidneys, which then secrete the hormone erythropoietin. This hormone stimulates proliferation and differentiation of red cell precursors, which activates increased erythropoiesis in the hemopoietic tissues, ultimately producing red blood cells.

4.The two main types of leukocytes are granulocytes and mononuclear leukocytes (agranulocytes).

5.Platelets contribute to the hemostatic process in two different ways.
