Explanation:
Detailed explanation-1: -When the left ventricle contracts, the mitral valve closes and the aortic valve opens. This is so blood flows into the aorta and out to the rest of the body. While the left ventricle is relaxing, the right ventricle also relaxes. This causes the pulmonary valve to close and the tricuspid valve to open.
Detailed explanation-2: -systole-this is when your heart contracts, pushing blood out of the chambers. diastole-this is the period between contractions when the muscle of your heart (myocardium) relaxes and the chambers fill with blood.
