1) The significance of a lower-than-normal hematocrit is that the patient could possibly have anemia. Anemia is when someone does not have enough hemoglobin which is the oxygen carrying protein in red blood cells. The effect of a bacterial infection is that it raises the white blood cell count which affects the hematocrit by lowering it. (MedlinePlus: Anemia, 2013)
2) The development of lymphocytes and other formed elements are both formed in a process called hemopoiesis. The process hemopoiesis means new blood cells are formed and usually takes place in the bone marrow. The difference between lymphocytes and other formed elements are that one gives life to red blood cells and platelets and the other gives life to lymphocytes. (Jenkins, Gail, Anatomy and Physiology from Science to Life, 2013, page 620)
3) Erythropoiesis is the production of red blood cells or erythrocytes. The production starts in the bone marrow and factors can speed it up or slow it down. If you lose a lot of blood, erythropoiesis will speed up and then anemia can cause erythropoiesis to slow down. (Jenkins, Gail, Anatomy and Physiology from Science to Life, 2013, page 624)
4) What happens if a person with type B blood receives a transfusion of type O blood? Nothing would happen because type B can receive type O. Type O is the universal donor. Also, type O has not antigens. (Jenkins, Gail, Anatomy and Physiology from Science to Life, 2013, page 626)
5) A lymphocyte is the white blood cell that has a round nucleus surrounded by a blue halo of cytoplasm with no visible granules. A basophil contains dense blue-purple granules that hides the nucleus. Monocytes have a U-shaped nucleus and a bluish, foamy cytoplasm with no visible granules. Neutrophils contain small, pale lilac granules and a four-lobed nucleus. Eosinophils contain red-orange granules and a two-lobed nucleus. (Jenkins, Gail, Anatomy and Physiology from Science to Life, 2013, page 632)
