galben [10]

The expansion of the aorta causes a rise in blood volume and blood pressure.

<h3>What is the cardiac cycle?</h3>

Heartbeat pattern The cardiac cycle includes all of the physiological processes connected to a single pulse, including the electrical, muscular (pressures and volumes), sensory, and other activities. During each cardiac cycle, both ventricles and atria beat alternately.

<h3>Briefing:</h3>

The human heart's cardiac cycle includes two phases: ventricular relaxation and atrial contraction. The right ventricle has low pressure when the right ventricular systolic pressure is frequently less than 30 mm Hg. The left ventricle has a thicker wall and more muscle mass than the right ventricle as a result of the blood flowing at a high pressure. The expansion of the aorta causes a rise in blood volume and blood pressure.
