ejection period
The aorta .
The right ventricle empties into the pulmonary arteries and the left ventricle empties into the aorta.
Blood flows into the relaxed atria while the ventricles contract. <rephrased> The ventricles contract, carrying blood into the aorta, and blood flows into the relaxed atria.
Into the heart
When relaxation or diastole is occurring in the atria blood flows through the atria and the AV valves into the ventricles. When contraction or systole is occurring in the atria the remaining blood that doesn't flow through during relaxation is pushed into the ventricles. As the atria relax, the ventricles begin contracting; ventricular pressure rises, closing the AV valves. Ventricular pressure continues rising until it exceeds the pressure in the large arteries stemming from the ventricles. The SL valves are forced open and blood is expelled from the ventricles into the aorta and pulmonary trunk. During this phase the ventricles relax because the blood is no longer compressed in their chambers. Blood expelled into the aorta and pulmonary trunk backflows toward the heart, which then closes the SL valves. During the ventricle contraction the atria stays in relaxation, filling with blood and when blood pressure on the atrial side of the AV valves exceeds that in the ventricles, the AV valves are forced open and ventricular filling begin all over again.

Afterload.
When the ventricles contract, the right ventricle pushes blood up through the pulmonary semilunar valve into the pulmonary arteries via the pulmonary trunk, and the left ventricle pushes blood up through the aortic semilunar valve into the Aorta.
Miocardia is the decreasing heart volume during systolic contraction. The rhythmic contraction of the heart, especially the ventricles, via which the blood is returned/ pushed through the aorta and pulmonary artery after each diostole.
Diastole is the relaxation of the cardiac muscles after having contracted and pumped out the blood into the arteries.Systole is the contraction of the ventricles of the heart which pushes the blood out of the heart.
The left Ventricle pumps blood out to your body
The right ventricles pumps blood to the lungs via the pulmonary artery. The left ventricle pumps blood to the body via the Aorta.
