Unit 10: Blood/Immunology Case Study Lab What were your three diagnoses? 1. Case 1: Sickle-Cell Anemia 2. Case 2: Mononucleosis 3. Case 3: Pernicious Anemia Journal Questions for lab 1. In what ways do normal red and white blood cells differ? Normal blood cells carry oxygen throughout the body. White blood cells fight against viruses, infections, and other foreign objects. 2. Which type of white blood cell would you expect to be most common in a normal blood smear?

Neutrophils 3. A differential count of white blood cells from a patient gave the absolute number of lymphocytes as 8000 per mm3 and the total number of white blood cells as 12,000 per mm3. Calculate the percentage of lymphocytes in this sample of white blood cells. Is this a normal or abnormal percentage? Explain your answer. You divide 8000 by 12000 and then times by 100. This will give you 2/3% (66. 67%) . this is abnormal regular is 20-40% 4.

Describe the difference between a communicable disease and an inherited disease. Use examples you have studied in this exploration to support your description. A communicable disease can be transferred for one person to one another. A inherited disease is passed by genetics. 5. Why white blood cells in a stained blood smear are usually counted at low power under a microscope? Explain your answer. Because they are bigger than other blood cells. . Why is the presence of a larger than normal number of neutrophils indicative of an infection? Explain your answer. Cause neutrophils fight infections so if there is a higher than normal that means that they are fighting off an infection. 7. Why would you not expect to see tissue macrophages in a blood smear? Explain your answer. Cause macrophages move within the tissue unless tissue is in the blood smear.
