Tell Me About Blood
1. The significance of lower than normal hematocrit is anemia. This can be caused by vitamin deficiency, loss of blood, bone marrow problems, or abnormal hematocrit. The effect of bacterial infection would cause not a decrease in hematocrit (420Allen)
2. Leukocytes are produced or stored in many locations in the body including: the thymus, spleen, and bone marrow. The two kinds of lymphocytes are B lymphocytes and T lymphocytes. Lymphocytes start out in the bone marrow and either stay there to mature into B cells, or they leave for the thymus gland, where they mature into T cells. Other formed elements, such as blood is a mixture of plasma and other substances which are developed through red blood cells or erythrocytes. Thrombocytes or platelets are formed by fragmentation of megakaryocytes in the bone marrow (411Allen)
3. Erythropoiesis is the process of red blood cell formation or production which begins in the red bone marrow as a proerythroblast. It then divides several times until it reaches the end of development, ejects the nucleus, and becomes a reticulocyte. These develop into erythrocytes within one or two days after release from the bone marrow. Erythropoiesis slows down when there is a decrease in oxygen carrying capacity of blood. It speeds up when the oxygen delivery to the kidneys and other body tissues fails.
4. If a person with type B blood were given a transfusion of type O blood, there would be no negative effects. Type O blood is the universal donor. This is true because the type O red blood cells do not have any antigen on them that would be attacked by the Anti A-Antibody on the type B red blood cell.
5. A-The white blood cell described is a Lymphocyte and functions to regulate immune responses. It also produces antibodies cancer cells, and other infectious microbes.
B- The white blood cell described is a Basophil and functions is to intensify the overall inflammatory response
6. White blood cells (WBCs) are typically
