What is meant by cardiac cycle? |
|
Answer» Answer: The atria and ventricles alternately contract in each cardiac cycle. The pressures in the chambers change greatly over the course of the cardiac cycle. The cardiac cycle is essentially split into two phases, systole (the contraction phase) and DIASTOLE (the relaxation phase).A cardiac cycle is defined as the steps involving the conversion of deoxygenated blood to oxygenated blood in the LUNGS and PUMPING it by the heart to the body through the aorta [40]. |
