Oxygenated blood is pumped out of the heart by the left ventricle.
Oxygenated blood
The left ventricle pumps blood to the aorta
Blood is pumped by both the left and right ventricles. Blood pumped by the right ventricle is to the lungs only while the left ventricle pumps to the rest of the body. This is why the walls of the left ventricle are significantly thicker than the walls of the right.
The right side of the blood receives deoxygenated blood from the systemic (body) circulation. The right atrium receives blood from the systemic veins and pumps it into the right ventricle. At that point, the right ventricle pumps that blood to the lungs.
rich oxygen
70 ml of blood are pumped out of the left ventricle with each contraction.
has poor oxygen in it
it gets pumped away from the heart
The blood is pumped out of the heart, when it is oxygenated, through the left atrium and left ventricle into the aorta.
The right ventricle pumps blood through the lungs to get oxygen and then gets pumped in the left atrium which is then pumped into the left ventricle that pumps the blood to the rest of the body.
Cardiac output is the amount of blood pumped by each ventricle in one minute. Stroke volume is the amount of blood pumped by each ventricle with each heartbeat. If you need a specific number: stroke volume x heart rate = Cardiac output
