I am only 11 but my mom has been a nurse for 28 years the reason is because of it contracting and expanding
a beating noise.

The sound of a heart beat is caused by the closing of the valves in the heart.
The first heart sound, the so called "lub", comes from the closure of the atrioventricular valve. The second heart sound, the "dup", comes from the closure of the semilunar valve.
The sound of a heart beat is usually described as a thump.
Well if you had what doctors call a stethoscope, then surely you will notice that when the headphones of the stethoscope are on your ears and when the plastic disk is placed against the patients chest right toward the heart. Then you will hear the patients heart pumping like the beating drums. So there for the heart makes a low beating sound.
The heart makes soun by the beating heart and the resultant flow of blood through it.
yes
Yes the "heart beat" is just the sound of the valves opening and closing, not the sound of the blood being pumped.
Bees make a buzzing sound, that is caused by the rapid beating of their wings.
