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.
