Pre-lab Questions
1. Research the process of erythropoiesis, and explain the role erythropoietin plays in the body.
Erythropoiesis refers to the production of more red blood cells. The kidneys produce them by
the action of the hormone erythropoietin. The kidneys promote hematopoiesis, which is the
creation of red blood cells in the bone marrow.
2. Based on your response to Question 1, above, why do you think erythropoietin is a popular
“doping” drug for athletes?
Athletes use "doping" substances to enhance their body's oxygenation. This medication
stimulates erythropoiesis, enhancing the athlete's oxygen-carrying ability. Increased oxygen
levels lead to enhanced energy levels for athletes, resulting in higher athletic performance.
3. How would the hemoglobin content differ in a person living in Philadelphia (Elevation: 39 feet)
compared to someone living in Denver (Elevation: 5280 feet)? Explain your reasoning using the
information you provided in Question 1.
Denver inhabitants have a distinct variation in hemoglobin concentration compared to those
residing in Philadelphia. This is a consequence of the environment having a lesser availability of
oxygen compared to locations at lower altitudes. Consequently, Denver inhabitants would have
elevated hemoglobin levels due to the decreased oxygen generation.

EXPERIMENT 1: CLASSIFICATION OF BONES
Introduction Questions
1. In this experiment, you will investigate the valves utilized by the heart. What other organs or
body systems incorporate valves? List and describe these, being sure to elaborate on how they
are used. (Hint: Your response should be 4-6 sentences long.)
Within the lymphatic ducts, there are valves that prevent fluid from flowing in the other
direction. The circulation of blood throughout the body and back to the heart is controlled by
the valves that are found in veins.
Data and Observations
Insert your observations for this experiment in the table below as detailed by the lab procedure.

displacement of water. displacement of water.
Results and Discussion
1. What happened when you pressed on the balloon stretched over the jar? What does this result
represent?
The water forcefully expelled from the balloon as a result of compression. This diagram
illustrates the function of the heart's valves in regulating the flow of blood. The valves prevent
the backflow of blood in the opposite direction.
2. What structure in this experiment mimics a heart valve?
The section of the balloon that is stretched over the jar and cut off acts as the structural
component in this experiment, like a heart valve.
3. How did the valve influence the experimental results? If possible, indicate the difference (in mL)
in water displaced with the valve versus without the valve. Does the valve enhance the water
flow, and why?
The valve influenced the result by allowing the pressure within the jar to increase. Augmented

pressure allows the straw to accommodate a greater amount of water. With the valve installed,
the volume in the beaker increased by 10 mL compared to when the valve was not there. The
valve enhances water flow by allowing pressure to accumulate inside the jar.
