Which component(s) of the cardiac cycle (atrial systole, atrial diastole, ventricular systole, and/or ventricular diastole) is/are directly responsible for the pulse tracing? During which phase of the cardiac cycle are the semilunar valves opened? What is the main function of the semilunar (aortic and pulmonary) valves?
What is "happening" during atrial systole? a. Both the atria and ...
In the cardiac cycle when you have atrial systole: A. the ventricular muscles contract B. the atrial muscles contract C. the ventricular and atrial muscles contract simultaneously D. the atrial muscles relax; In ventricular systole, the right ventricle is the first to expel blood, but the left ventricle is the first to begin contracting.
