Summary Introduction
To review:
The advantages of higher levels of chemical BPG and erythrocytes resulting from the training of athletes at higher heights, over a time period.
Introduction:
Erythrocytes are also known as RBCs (red blood corpuscles). These are the type of blood cells used by the body to transport oxygen (O2) to various body tissues. Whereas, BPG (2, 3- bisphophoglycerate) is a chemical compound produced by erythrocytes during a reaction in the process of glycolysis. It can easily bind to the deoxygenated Hb (hemoglobin) as compared to oxygenated Hb.

What are the physiological advantages in sport due to using erythropoietin?
What are the physiological consequences of using erythropoietin?
Give an example of a Professional Athlete that used erythropoietin (Armstrong does not count).
Why do endurance athletics use erythropoietin?
. Do you think erythropoietin levels in athletes at low altitude are lower, higher, or the same after
training at a high altitude for 2 months? Explain your answer.
Calculate the average ml of oxygen molecules in 100 ml blood in the athletes at low altitude and
then in athletes in high altitude while training at high altitude. Use the following information: 1.39 ml
of oxygen per gram of hemoglobin.
. Do athletes training at high altitudes have more or less oxygen molecules per ml of blood then
athletes training at low altitudes? Explain why this difference gives athletes who train at high
altitudes an advantage over athletes who train only at low altitudes.

What effect does it have on hemoglobin levels. Choose from the following: (A) hyperthyroidism would increase the number of erythrocytes and the amount of hemoglobin (B) hyperthyroidism would decrease the amount of hemoglobinarrow_forward. Cardiac output In the late 1860s, Adolf Fick, a professor of physiology in the Faculty of Medicine in Würzberg, Germany. developed one of the methods we use today for measuring how much blood your heart pumps in a minute. Your cardiac output as you read this sentence is probably about 7L/min. At rest it is likely to be a bit under 6 L/min. If you are a trained marathon runner running a marathon, your cardiac output can be as high as 30 L/min. Your cardiac output can be calculated with the formula where Qis the number of milliliters of CO, you exhale in a minute and D is the difference between the CO, concentration (ml/L) in the blood pumped to the lungs and the CO, concentration in the blood returning from the lungs. With Q - 233 ml/min and D - 97 - 56 - 41 ml/L, 233 ml/min 5.68 L/min, 41 ml/L fairly close to the 6 L/min that most people have at basal (resting) conditions. (Data courtesy of J.

- It is not usually necessary to assess arterial blood gases when diagnosing and treating asthma. However, this information can sometimes be useful in severe asthma attacks. Suppose that a patient had a PO2 of 60mm hg and a PCo2 of 30mm hg when the patient first went to the emergency room.
