Journal Questions for lab

1. In what ways do normal red and white blood cells differ?

Many red blood cells circulate in the bloodstream, while the white blood cells leave the blood.

2. Which type of white blood cell would you expect to be most common in a normal blood smear?


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.

To get the percentage of lymphocytes in White Blood Cells, you divide 8000 by 12000 and multiply by 100. This will give you 66.67% of lymphocytes in White Blood Cells. This is an abnormal percentage, because normal values of lymphocytes in blood, 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 is an infectious disease that can be transmitted from one individual to another. An inherited disease is a disease passed through genetics. An example of a communicable disease is mononucleosis, which can be transmitted through an infected person’s saliva with a clean person’s saliva. An example of an inherited disease is sickle-cell anemia.

5. Why are white blood cells in a stained blood smear usually counted at low power under a microscope? Explain your answer.

Because 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...
