Journal Questions for lab

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

Normal red cells affect only the blood and normal white blood cells affect the immune system.

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

The type of blood cell I expect to be most common in a normal blood smear is Neutrophil.

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.

8,000/12,000x100=66.7% the normal percentage is approximately between 20-40% and the WBC count is not normal.

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

Communicable diseases are one that can spread through either direct or indirect contact. An example of a communicable disease is the cold or flu. When someone coughs, the body does this as a defense mechanism so that the germs spread through the air to others. Inherited diseases are diseases that are passed down from generation to generation. Sickle cell anemia is an example of an inherited disease. This is due to the fact that the disease is passed down by the parents by either having or being carriers of the disease.

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

White blood cells are larger than most other cells so if you were to view them at a higher pressure they might look like the other cells.

6. Why is the presence of a...
