Journal Questions for lab

1. In what ways do normal red and white blood cells differ? Red blood cells are the most common blood cells. Unlike RBC’s which stay in the blood stream, many WBC’s leave the blood stream to fight diseases. RBC’s have a nuclei and WBC’s don’t.

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. This is an abnormal amount of lymphocytes because you are only suppose to have between 20-30% of white blood cells as lymphocytes, and in the scenario given the lymphocytes consists of 67% of the white blood cells.

4. Describe the difference between a communicable disease and an inherited disease. Use examples you have studied in this exploration to support your description. An inherited disease is on that you are born with that was passed down in your genes from your parents, and a communicable disease is one that spreads from person to person.

5. Why are white blood cells in a stained blood smear usually counted at low power under a microscope? Explain your answer. WBC’s are usually found on lower powers because there are much more RBC’s than WBC’s. On a high power you would only be able to see RBC’s because of the magnification and the small amount of WBC’s. So, instead of taking forever to move the slide around at a high power in an effort to find the few WBC’s it is easier to look at them on a low power where u have a wider range of thing you can see.

6. Why is the presence of a larger than normal...
