Question

The preload is approximately the same as the ________.

A) end-diastolic pressure
B) end-systolic pressure
C) aortic systolic pressure
D) aortic diastolic pressure
E) atrial pressure

Answer 1

The preload is approximately the same as the end-diastolic pressure.

Step-by-step explanation:

The preload is approximately the same as the end-diastolic pressure. End-diastolic pressure refers to the pressure in the ventricles at the end of atrial systole, just before ventricular contraction. It represents the amount of blood filling the ventricles before they pump blood out to the rest of the body.
