Question

Identify the time in which each stage in the given figure is occurring.

Accepted Answer

The given image is showing the different stages of cardiac cycle which includes the series of events that occur inside the heart during the contraction and relaxation of the heart chambers. In other words, it includes the events that occur in the heart from the initiation of one heartbeat to the next. This cycle lasts for a duration of 0.8 seconds. The three phases of the cardiac cycle are:

The red curved line from 0-0.1 seconds is showing the atrial systole during which the pressure inside atria increases and the semilunar valves are closed. This phase lasts for 0.1 seconds. Rest of the time in the cardiac cycle, the atria relax (atrial diastole) i.e. for 0.7 seconds.

The red curve from 0.1 to 0.4 seconds depicts the ventricular systole that lasts for 0.3 seconds during which the pressure inside the ventricles increases and the blood flows from the heart to aorta and pulmonary artery. Rest of the time in the cardiac cycle, the ventricles relax (ventricular diastole) i.e. for 0.5 seconds.
