Write the equation relating mean arterial pressure to cardiac outputand total peripheral resistance?

A person has an ejection fraction of 54% and an EDV of 130 mL. a) what is their stroke volume b) if they have a heart rate of 65 beats per minute, what is the cardiac output?  c) If they increase their ED to 170 mL, what do you expect might happen to their ejection fraction (improve, stay the same or get worse)? Why- be complete in your answer. d) What law is this? e) How might the EDV be increased? Give at least one mechanism in detail

What changes in the vascular system during exercise account for the change in peripheral resistance?

Explain how the cross-sectional area of vessels (in cm2, range from 0 to 5000) affects the mean linear velocity of blood (in cm/s, range from 0 to 50) and blood pressure (in mm Hg, range from 0 to 100). Hint, draw a general model of vascular structure from the aorta to the vena cava, and plot how the variables mentioned above change as blood moves along the vessel system.

What physiological mechanisms or elements limit cardiovascular performance?
