I need these questions answered as well please
Discussion 1. How does the heart rate from the subject at rest, immediately after exercise, and at 1 min, and 2 min after exercise compare? Explain the physiological reasons for any differences. 3. What is occurring during the P-Q interval? How do the average P-Q intervals from rest and each time interval compare? How does the average at rest value compare to the "normal" value? 4. What is occurring during the Q-T...

At a resting pulse rate of 77 beats per minute, the human heart typically pumps about 71 mL of blood per beat. Blood has a density of 1060 kg/m3. Circulating all of the blood in the body through the heart takes about 1 min for a person at rest. Approximately how much blood is in the body? volume of blood in body On average, what mass of blood does the heart pump with each heart beat? kg mass per heart...

1. Please identify the 4 chambers of the heart, and the 4 valves that regulate flow through the heart and out of the heart. 2. Describe how the heart sounds (S1 and S2) relate to our understanding of the cardiac cycle. How does this correlate with the EKG tracing? Why is this coordination critical in enabling the heart to develop pressure gradients, and maintain adequate cardiac output? 3. We discussed the Frank-Starling Law of...

1. Based on the subject above, Did the analysis of lung volumes
indicate any restrictive or obstructive defect at rest? Did
the subject meet any of the ACSM clinical recommendations to
warrant a pulmonary function test?
2. How did FVC, FEV1/FVC and FEV1 change after
exercise? Based on these changes, does the subject appear to have
any exercise induced asthma?
