In all mammals, the heart is double pump. Each side of hte heart has an upper and lower chamber. The top chamber are called atriums and lower chamber are called ventricles. A one way flap called a valve connects the upper and lower chambers. when the heart muscle relaxes, blood flows through the open valves from the atriums into the ventricles. when the heart contracts, the flap is closed with a thump. the valve prevents the blood from moving back into the the atrium, and it is forced out of the heart through another opening. The sound from the valves can be heard through the tissues of the body and is often described as a lub-dub sound. I hope this helps everyone my son did this project for his science fair at Pioneer Academy of Science, Clifton NJ . Great project

Why does the ear gong sound louder when you put your fingers in your ears?
When you put your fingers in your ears, you create a seal that reduces the escape of sound waves, focusing the vibrations within the ear canal. This amplifies internal sounds, such as your heartbeat or the sound of your own voice, making them seem louder. Additionally, blocking external noise allows these internal sounds to stand out more, contributing to the perception of increased volume.

Which part of the heart makes the heartbeat sound?
A heartbeat produces the familiar "LUB-DUP" sounds as the chambers contract and the valves close. The first heart sound, "lub," is heard when the ventricles contract and the atrioventricular valves close. This sound last longest and has a lower pitch. The second heart sound, "dub," is heard when the relaxation of the ventricles allows the semilunar valves to close.
