Answer 1

The longest phase of cardiac cycle is Atrial diastole.

Explanation:

The longest part of the cardiac cycle is arterial diastole, which is divided into 0.1 seconds for auricular systole, 0.3 seconds for ventricular systole, and 0.4 seconds for joint diastole. Even during ventricular diastole, it enters the diastolic phase after auricular systole.
