Textbook Question
Chapter 11, Problem 38SAE
Two elements determine blood pressure—the cardiac output of the heart and the peripheral resistance, or friction, in the blood vessels. Name two factors that increase cardiac output. Name two factors that increase peripheral resistance.

Frank-Starling law of the heart states:
if you increase the stretch of the cardiac muscle fibers you will decrease the force of contraction
a greater end diastolic volume will produce a weaker contraction of the ventricle
by increasing the force of ventricular contraction you will increase the end systolic volume
if you increase the stretch of the cardiac muscle fibers you will increase the force of contraction.
Estimate the volume of a human heart (in mL) using the following measurements/assumptions:
Blood flow through the aorta is approximately 16.8 cm/s.
The diameter of the aorta is approximately 3.0 cm.
Assume the heart pumps its own volume with each beat.
Assume a pulse rate of 90 beats per minute.
In the figure below on the left, label the P, QRS and T waves. Describe what is happening in the heart in the P wave:
Relate the P wave to the cardiac cycle:o Is the heart in systole or diastole?o Is the pressure high or low?o Where is blood flowing? Which valves are open? closed? o Which muscle fibers are contracting, if any?
