Unit 10: Blood/Immunology Case Study Lab
What were your three diagnoses?
1. Case 1: bacterial or viral infection
2. Case 2: mononucleosis
3. Case 3: normal bloods smear
Journal Questions for lab
1. In what ways do normal red and white blood cells differ?
a. Red blood cells carry oxygen to the whole body through the blood...hence, why blood is red whereas white blood cells, or leukocytes, are of the immune system defending the body against viruses, infections, etc.
2. Which type of white blood cell would you expect to be most common in a normal blood smear?
a. 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.
a. To get the percentage of lymphocytes in WBC = 8000/12000* 100 = 66.67%. A normal value of lymphocytes in blood is 20% - 40% so yes it is an abnormal percentage.
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 diseases are the ones which can be transmitted from one individual to another by water, air, food, insects etc. e.g. cold, chicken pox it can be transmitted from one to another by cough sneeze of the infected person.
5. Why are white blood cells in a stained blood smear usually counted at low power under a microscope? Explain your answer.
a. They are much bigger than all the other blood cells. If you try to count them on high power you have to keep moving the slide around and it is really easy to get confused by other cells and lose count. On low power the other cells are much less visible, and you get a broader picture of the white cells making...
