Pre-Lab Questions: “1. Research the process of erythropoiesis, and explain the role erythropoietin plays. Why is this a popular “doping” drug for athletes? “ The creation of new red blood c... ells that occur in the bone marrow is known as erythropoiesis. The hormonal erythropoietin is secreted by the kidneys to increase the production of red blood cells. Erythropoietin is secreted when the oxygen concentration drops in order to boost the production of red blood cells, which raises the oxygen levels. This is a common "doping" substance used by sportsmen when erythropoietin increases the production of red blood cells, which increases oxygen absorption. “2. How would the hemoglobin content differ in a person living in Philadelphia (Elevation: 39 feet) compared to someone living in Denver (Elevation: 5280 feet)? Why? “ At higher elevations, the oxygen concentration is low. The difference in the haemoglobin content is as a result of different heights above the sea level. Highly elevated area (Denver’s 5280) has less oxygen in the air compared to the low land area in Philadelphia which has a large air column. Experiment 1: Heart Valves and Pumps Table 2: Experimental Observations Observations (with valve) and mL H2O Displaced? Observations (without valve) and mL H2O Displaced? Less amount of water displaced when pressure is applied More amount of water displaced when pressure is applied. Post-Lab Questions “1. What happened when you pressed on the balloon stretched over the jar? What does this result represent? “ Pressing of a balloon over a jar resulted to a lot of pressure that forced the water up the straw. It illustrated the functioning of the heart. “2. What structure in this experiment mimics a heart valve? “ The cut off section of the balloon that was stretched over the jar “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 experiment's findings were affected by the valve because of the canning jar's increased pressure. More water would be forced up into the straw because of the increased pressure. When the valve was in place compared to when it wasn't, there were 5 mL more of water. The valve improves water flow by causing the jar's pressure to increase. [Show More]
