24 10.5 Essay Questions 1) Scott's blood test shows that he has excess red blood cells. Identify and describe two causes of this disorder. Answer: Scott's disorder is polycythemia, which results from excess numbers of erythrocytes in the blood. This disorder may result from: 1. Bone marrow cancer (called polycythemia vera) 2. Life at a high altitude where the air is thinner and less oxygen is available (called secondary polycythemia) Increased sluggishness of the blood results from polycythemia. Page Ref: Bloom's: 3) Application 2) Discuss why Martina, who has blood type A, cannot receive blood type B during a transfusion. Answer: Martina has the antigen for A on her red blood cells. During infancy, her body built anti-b antibodies since she lacked that antigen in her blood. If she receives a transfusion of blood type B, her body will already have the anti-b antibodies in place. Agglutination will occur as the anti-b antibodies bind and clump to the foreign B antigen. The red blood cells will be lysed, hemoglobin will be released into the blood stream, and these events would lead to a transfusion reaction. Page Ref: 349, 351 Bloom's: 2) Comprehension 3) While looking through a microscope in your anatomy lab, you see a cell whose cytoplasm has a pale pink color with fine granules and a tri-lobed deep purple nucleus. Determine what type of cell you see (be specific). Explain why you made this selection. Answer: You have likely seen a neutrophil, a type of leukocyte, while looking through the microscope. Neutrophils are granulocytes with a pale pink cytoplasm and fine granules that are difficult to see. Neutrophils have nuclei with three to seven lobes connected by thin strands of nucleoplasm. Page Ref: 343, 344 Bloom's: 3) Application 4) Describe the three phases of the normal blood-clotting process. Answer: Hemostasis involves three major phases. The first phase is the vascular spasm phase, in which serotonin released by the platelets causes the blood vessels to spasm and constrict, thus decreasing blood loss. The second phase is the platelet plug formation, in which platelets become "sticky" and cling to the site of injury. The third phase is coagulation wherein thromboplastin interacts with PF3 and calcium, as well as other blood proteins, to form prothrombin activator. Prothrombin activator converts prothrombin to thrombin, which then joins with fibrinogen to form fibrin, the basis of the clot. Page Ref: 347 Bloom's: 2) Comprehension 24
25 5) Which situation do you predict to prompt the release of more erythropoietin into the blood: anemia or polycythemia? Explain. ny decline in the level of oxygen in the blood prompts the kidneys to release more erythropoietin into the blood. Erythropoietin targets the bone marrow to produce more red blood cells. Anemia is a decrease in the blood's ability to transport oxygen for any reason while polycythemia is an excessive or abnormal increase in the number of red blood cells. Therefore, anemia would prompt the release of more erythropoietin so that the blood could transport more oxygen. In fact, polycythemia would inhibit erythropoietin production by the kidneys. Page Ref: 341, Bloom's: 3) Application 6) Describe ABO and Rh blood groups. Answer: The blood groups are based on the presence or absence of specific surface antigens. Blood group A has type A antigens on their RBCs, blood group B has type B antigens on their RBCs, blood group AB has both type A and type B antigens on their RBCs, and blood group O lacks either type A or type B antigens. The Rh+ blood group indicates the presence of the Rh antigens on their RBCs. Individuals belong to blood groups A, B, AB, or O, and they are also classified as either Rh+ or Rh-. Page Ref: 349, 351 Bloom's: 2) Comprehension 7) Explain agglutination as it relates to blood groups. ntigens are surface proteins found on all cells including blood cells. In the case of blood groups, an individual's blood type reflects the presence or absence of specific antigens. An antigen-antibody response is initiated if the individual receives a transfusion of blood containing antigens that it identifies as being "foreign." Antibodies found in a person's blood bind to the foreign antigen, causing agglutination, or clumping. The antigen-antibody complexes clog the small blood vessels, and the foreign RBCs are lysed, releasing hemoglobin into the bloodstream. The most serious complication of a transfusion reaction is kidney failure due to blockage of the kidney tubules by the hemoglobin molecules. Page Ref: Bloom's: 2) Comprehension 8) Mrs. Litaker was concerned because her baby was born with yellow skin. Name and explain this condition to her. Answer: This condition is known as physiologic jaundice and it arises because fetal red blood cells are destroyed at a rate faster than the newborn's liver can rid the body of the hemoglobin breakdown products in bile. This form of jaundice typically causes no major problems. Page Ref: Bloom's: 3) Application 25
