Description
All Experiments are attached below. Please answer each one in its file and send them back, DO NOT MIX THEM, BECAUSE EACH EXPERIMENT HAS A DIFFERENT DROPBOX TO SUBMIT.Please, if there are any questions, let me know. Do not hesitate yourself by asking me. I hope everything is clear for you in the attached files.

PRE-LAB QUESTIONS
1. Research the process of erythropoiesis, and explain the role erythropoietin plays. Why is this
popular “doping” drug for athletes?
2. How would hemoglobin content differ in a person living in Philadelphia (Elevation: 39 feet) as
compared to someone living in Denver (Elevation: 5,280 feet). Why?
EXPERIMENT 3: MICROSCOPIC ANATOMY OF BLOOD
Post-Lab Questions
1. What makes red blood cells unique compared to other cells in the body?
1. How is new blood made?
2. What is the main function of platelets?
3. Describe how the body stops bleeding.
4. Sickle cells are named because of their characteristic shape. What problems can this shape
cause?
5. Explain how the absence of a nucleus affects a red blood cell’s life span.
Post-Lab Questions
1. Describe the differences you observed between the water, 4% EDTA, and 8% EDTA treatments.
1. Does the water serve as a positive or negative control? How do you know?
2. Research and determine the composition of eggshells. State your findings below, and indicate
why this composition makes eggshells a good material for EDTA to chelate.
3. EDTA is a synthetic amino acid, which the body perceives as a foreign substance. EDTA is
therefore delivered to the kidneys and removed from the body in urine. Explain how this
process also leads to the removal of heavy metals.
4. Based on your results, do you believe chelation therapy would be an effective treatment for
atherosclerosis? Support your argument with experimental evidence.
EXPERIMENT 2: EFFECT OF CHELATION THERAPY ON ARTERIAL PLAQUE

Post-Lab Questions
1. What happened when you pressed on the balloon stretched over the jar? What does this result
represent?
1. What structure in this experiment mimics a heart valve?
2. How did the valve influence the experimental results? If possible, indicate the difference in
water displaced (in mL) with the valve versus without the valve. Does the valve enhance water
flow? Why?
3. What other organs or body systems incorporate valves? How are they used?
