Erythropoiesis is the development of red blood cells. There are several recognizable steps in this lineage:. Granulopoiesis is the process by which white blood cells develop. The myeloid series has the most characteristic cell lineage:. Eosinophils and basophils undergo sequential stages of differentiation in a very similar manner to those of neutrophils.

Their specific granules are also produced during the myelocyte stage. The platelet lineage is similar. Large, multilobed promegakaryocytes develop into megakaryocytes, which are the largest cells of the bone marrow 30 to 40 microns. Platelets form through the segmentation of these cells. Monocytes develop from promonocytes and lymphocytes develop from prolymphocytes. These elements are difficult to distinguish in normal bone marrow smears.

Pre-Lab Quiz What is the difference between blood, plasma, and serum? Answer: Blood is the combination of blood cells with acellular plasma. Plasma is the blood minus the cells. Serum is plasma without clotting factors or fibrin. Answer: This drawing should show the biconcave disc shape from above and the dumbbell shape in the cross section. The reticulocyte would look the same as the RBC but would also contain organelles. All cells are 7. Answer: You would expect to see an increase in the number of eosinophils, which typically respond to helminthic parasites by degranulating, since these parasites are large and cannot be phagocytosed.

Answer: This patient most likely has a bacterial infection. Neutrophil counts are raised in the acute inflammatory response to bacteria.

They recirculate through tissues and back to the circulation via blood and lymphatic vessels.

They migrate into tissues and differentiate into the various macrophages of the mononuclear phagocytotic system. Plasma cells usually differentiate from B-lymphocytes in tissues and produce large amounts of antibodies. This is a rare example of one found in blood. Chapter 7 - Peripheral Blood Blood is a specialized connective tissue composed of cells red blood cells , white blood cells , and platelets circulating in a fluid called plasma.
