Research the process of erythropoiesis, and explain the role erythropoietin plays in the body. The process by which red blood cells are made i n the bone marrow is called erythropoiesis. This process is accelerated by the hormone erythropoietin (EPO), which is mostly generated in the kidneys in response to low blood oxygen levels. Because EPO raises red blood cell count, improves oxygen transport to muscles, and boosts endurance, athletes abuse it as a "doping" medication. However, because of the serious health dangers and potential difficulties involved, such usage is forbidden and dangerous. 2. Based on your response to Question 1, above, why do y ou think erythropoietin is a popular “doping ” drug for athletes? Erythropoietin (EPO) is a drug used by athletes to increase the synthesis of red blood cells (RBCs) and improve oxygen delivery to their muscles. Competing athletes adore it because it boost s their oxygenation levels, which enhances their performance and endurance. Despite moral and health issues, some athletes use EPO to increase performance and endurance. 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. Living in Denver, which is at an elevation of 5280 feet, would result in a higher hemoglobin content than liv ing in Philadelphia, which is at an elevation of 39 feet. This is due to living in higher altitudes —like Denver —causes the air's oxygen content to drop. The body produces extra hemoglobin, the protein responsible for delivering oxygen in the blood, to make up for the decreased oxygen availability and to better adapt to higher altitude settings. Lab 10 Blood and the Heart BIO202L 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.) The heart is one of the numerous organs and systems that depend on valves. 1. Vein valves also prevent blood from flowing backward in addition to the heart. These venous valves permit blood to flow back to the heart against the force of gravity, particularly in the lower limbs. Valves in lymphatic veins enable the two -way passage of lymphatic fluid to lymphatic nodes and back into circulation. 3. The esophagus has a valve that regulates food transit and stops acid reflux. 4. The ureters contain a valve that prevents urine from spilling over from the bladder into the kidne ys. All physiological functions depend on the suppression of reverse motion and the smooth flow of fluid through valves. Data and Observations Insert your observations for this experiment in the table below as detailed by the lab procedure. Table 1: Ex perimental Observations Observations (with valve) and mL H2O Observations (without valve) and mL H2O Displaced? Displaced? There will be no water leakage through the straw Water leaks out of the balloon momentarily when you squeeze the balloon. when you press down on the straw. Over ten milliliters of water were extracted overall. Results and Discussion 1. What happened when you pressed on the balloon stretched over the jar? What does this result represent? Water is released from the balloon wh en it is inflated from the side of the balloon without a valve, also referred to as the balloon neck. If the valve side of the collar is taped, water cannot escape once the balloon is stretched over the jar. This experiment illustrates how the heart's valves work when the heart is pumping. The area of the straws where the balloon is attached symbolizes the role of the heart valves in controlling regurgitation, whereas the heart beats. 2. What structure in this experiment mimics a heart valve? The straw's end is connected to the balloon's neck, which symbolizes the heart valve.
