Yes the "heart beat" is just the sound of the valves opening and closing, not the sound of the blood being pumped.
Oxygenated blood is pumped out of the heart by the left ventricle.
Blood goes into the right side of the heart from the body then pumped to the lungs for purification( this is when oxygen is mixed with haemoglobin( a substance in the body) to make the blood cleaned, it is then pumped to the left side of the heart were it is transported to every part of the body, then the circulation starts all over again.............
The oxygen(rich)- and poor blood which are pumped in and out of the heart in the ventrical and atrium,with the help of mucsles, creates a sound (which is the sound that you hear)It is the blood getting pumped
blood that is being pump from the heart to the lungs is oxygen.
During aerobics exercise, lungs take in air and transfer oxygen to the blood, which is then pumped by the heart to the muscles that need it.
Carbon dioxide is at high levels and oxygen at low levels in blood that is being pumped from the heart to the lungs.
it is pumped out of the lungs
Blood is pumped out of heart. It comes back to the heart. This circle goes on.

blood is pumped around your body by your heart, that's why you hear your heart beating because it us pumping the blood around your body :)
it is pumped to the heart first then to the lungs
The blood absorbs oxygen from the lungs - enabling it to be transported throughout the body.
The blood is pumped out of the heart, when it is oxygenated, through the left atrium and left ventricle into the aorta.
The left venricular chamber of the heart is responsible for pumping the blood throughout the body
