Question

place the steps of the cardiac cycle in order, from start to finish.

1. ventricular diastole - early
2. atrial systole begins
3. ventricular diastole - late
4. ventricular systole - second phase
5. atrial systole ends, atrial diastole begins
6. ventricular systole - first phase

Explanation:

The cardiac cycle starts with atrial systole (step 2). Then atrial systole ends and atrial diastole begins (step 5). After that, ventricular systole - first phase (step 6) occurs, followed by ventricular systole - second phase (step 4). Then comes ventricular diastole - early (step 1) and finally ventricular diastole - late (step 3).

Answer:

2, 5, 6, 4, 1, 3
