AP 2 Cardiovascular System
Cardiovascular System: Blood
Laszlo Vass, Ed.D. Version 42-0007-00-01
Purpose
Explain why you did this lab and what if any safety precautions needed to be followed.
Exercise 1: Observing Your Own Blood
Observations
A. Sketch and describe what you saw on the prepared slide of human blood:
B. Sketch and describe what you saw on the blood smear slide using your own blood:
Questions
A. What are the components of blood?
The components of blood include red blood cells, white blood cells, platelets, and plasma. Some blood cells carry oxygen (necessary for metabolic reactions), some blood cells fight off invading substances that could destroy your cells, and other blood cells help to form clots, which keep your body from losing too much blood
B. What is the function of red blood cells?
The red blood cells, which are also called erythrocytes which have the important responsibility of carrying the oxygen throughout the body
C. List the five types of leukocytes and describe the function of each.
Basophils release histamines. Histamines are small chemical molecules that cause your body to swell up with hives, itch sneeze, wheeze, and get teary-eyed when you are around something to which you are allergic. All of those reactions cause inflammation, which enlists the help of stronger white blood cells. Sneezing and getting watery eyes are physiologic reactions to help flush the offending allergen from your mucous membranes.
Eosinophils “eat” other cells. The technical term for the eating of a cell is phagocytosis, so eosinophils are said to phagocytize complexes formed between antigens and antibodies.
Lymphocytes kill cells that contain viruses. Lymphocytes scan the body looking for viruses. There are two types of lymphocytes: B cells and T cells. T cells
