Journal Questions for lab

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

-RBC circulates in the blood stream, while many of the WBC leave the bloodstream to go fight disease organisms in tissues.

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

-There are five different types of WBCs in a normal blood smear. The most common one would be the neutrophils there I about 60%-70% of them.

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.

-The percentage you will get will be 66.67% which is high because the normal range is 20%-40% so yes, this is an abnormal percentage of lymphocytes in this sample of WBC.

4. Describe the difference between a communicable disease and an inherited disease. Use examples you have studied in this exploration to support your description.

-The difference between a communicable disease and an inherited disease is an inherited disease is a disease you get from your parents when you’re just a little infant either they are carriers of a certain trait or that trait is just a dominant trait. Such as Sickle-Cell Anemia this is a inherited disease that parents can pass to their infants. A communicable disease is a disease you can spread to other peers and people by just coming in contact with them or being around them; such as Mononucleosis known as the “Kissing Disease”.

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