Question
Chapter 13, Problem 42RA
Summary Introduction
To review:
Variation in the pressure of the ventricles during the duration of the first heart sound.
Introduction:
Pressure present within the ventricles during systole and diastole phase is called intraventricular pressure. The systole and diastole causes the movement of the blood through the heart chambers. Systole is denoted by the contraction of the chambers, whereas diastole represents the relaxation of the chambers of the heart.
