KengaRu [80]

The phase in the cardiac cycle when the mitral valve is closed and the aortic valve is open is the systolic ejection phase (Option D). It is the second phase of the ventricular systole.

The cardiac cycle is a sequence of contraction and relaxation of the atria and ventricles to pump blood throughout the body.

This cycle (cardiac cycle) can be divided into two major periods: diastole and systole.

The diastole is when the heart relaxes and refills with blood, while the systole is when the heart contracts and pumps blood.

The systolic ejection phase is the second phase of the ventricular systole where blood is pumped from the ventricle.
