Given the functions of the cardiovascular and respiratory systems, why would heart rate and respiratory rate both change during exercise?

You mention is it beneficial to train in high altitudes. Which physiological changes occur in the body in response to lower partial oxygen pressures?.. .

Discuss and conclude the results given for the effects of exercise on breathing and heart rate.

Ranking the factors that have the most effect on a person’s vital capacity are:  (1) Age, (2) Sex ,(3) Height, (4) Weight , (5)Activity level or athletics, explain why. (If you dont agree with the ranking, you can change it but still explain why)

Altitude effects on exercise are caused mainly by increased CO2 production due to the physiological response to low pressure the increased influence of nitrogen gas at higher altitudes lowered 02 partial pressure the direct effect of low pressure on breathing

Calculate the Cardiac output per minute from the following parameter: Oxygen consumed per minute by the lungs: 200mL Oxygen content of Pulmonary veins: 200mL/L Oxygen content of Pulmonary artery: 160mL/L

A person who lives close to sea level and usually goes jogging in the morning. When that person runs at a place like Denver with high elevation she notices she isn't able to run as fast up in Denver as she usually does at home. She knows it is colder and there is less oxygen at high elevation than there is at his home. Why she feel like she didn't have the energy to keep up with her usual pace. a. her body wasnt able to begin glycolysis due to lack of oxygen b. her body was producing less ATP due to lack of oxygen  c. her body wasnt getting enough external heat input

What effect does a pacemaker potential have on a smooth muscle cell?

Calculate CO (cardiac output) if given HR and SV.

The effect of exercise upon the redistribution of blood pulse rate and ventilation changes
