Question

Put the phases of the cardiac cycle in the correct order, starting after ventricular filling.

Answer 1

The cardiac cycle sequence after ventricular filling starts with atrial systole, followed by ventricular systole (including isovolumetric contraction), atrial diastole, and ventricular diastole, finally leading back to ventricular filling.

Step-by-step explanation:

Phases of the Cardiac Cycle

The phases of the cardiac cycle proceed in a specific order after ventricular filling, which is crucial for the efficient pumping of blood throughout the body. To understand the correct sequence of events:

1. 
   
3. 
   
5. 
   
7. 
   
9. 
   

The coordination of these phases is essential for the heart to function properly and can be correlated with events on the electrocardiogram (ECG) as well.
