left ventricular ejection fraction.
Contraction: 'eject' the blood out of the heart due to reduce in size of heart chamber. From left ventricle, the blood will be pushed into the systemic circulation whereas on the right ventricle, the dehydrogenated blood is pushed into the pulmonary circulation (ie: lung). Relaxation: allow the heart to be filled with blood. Freshly oxygenated blood from the lung will move into left atrium and so thus the left ventricle whereas on the right side of the heart, blood now started to fill in the right atrium and the right ventricle again.
The "beat" of your heart is the contraction of the right and left ventricles. The right atrium passes blood from the body into the right ventricle -- when the ventricle contracts, it forces shut the valve leading back to the atrium, and the blood is pushed into the pulmonary arteries that lead to the lungs. The blood returns from the lungs to the left atrium, and flows into the left ventricle. When the left ventricle contracts, the blood is pushed out of the ventricle into the aorta, the body's main artery, to be carried through the arterial system to the various parts of the body.

Buoyancy
Cardiac output is the blood volume pushed out by the left ventricle per minute. Stroke volume is the volume of blood pushed out of the left ventricle per contraction of the heart (each heart beat). So stroke volume into heart rate / minute gives you cardiac output.
The papillary muscle.
The aorta itself does not lead to a specific chamber of the heart. Upon the final stages of the contraction of the heart, blood that is present within the left ventricle of the heart is pumped out of the left ventricle, and is pushed into the aorta, which is the largest artery in the human body. The aorta itself gives rise to all of the other arteries of the body.
when the right ventricle contracts it is pushed to the blood to the pulmunery arteries and to the capilaries of the lungs whee exchange of gases tkes place
The blood is pushed to lungs, via pulmonary aorta. The tricuspid valve prevents the back flow into right atrium.
stroke volume (SV) is the volume of blood pumped from one ventricle of the heart with each beat. It is calculated by subtracting the volume of blood in the ventricle at the end of a beat (called end-systolic volume) from the volume of blood just prior to the beat (called end-diastolic volume). The term stroke volume applies equally to both left and right ventricles of the heart. These two stroke volumes are generally equal, both approximately 70 ml in a healthy 70-kg man.Stroke volume is an important determinant of cardiac output, which is the product of stroke volume and heart rate. Because stroke volume decreases in certain conditions and disease states, stroke volume itself correlates with cardiac function.
The aortic valve allows the blood to leave the left ventricle.
