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
A heartbeat has two parts the first part in the flow of the blood into the heart. The second part is the flow of the blood out of the heart. That is why heart beat is a bub-bub sound.
Yes they do. They make a taping sound
There are all kinds of animals that make the toot sound. Humans for example are one animal that makes that sound.
Sound waves are what make up sound (sound waves=sound) so I would suppose so.
Main sound is sawing sound.
The heart valves.
thump thump!
They are called Lubb Dubb
Does a heart make decibels? Never heard a heart.
are related the sound because is cionsideriza to heart beat hahahahha.
the sound of a heartbeat
A tiny dinosaur banging a drum
The first sound, LUB, is made after the ventricular systole due to the shutting of bicuspid and tricuspid (AV) valves.
hes a Dj
Heartbeat. By Taana Gardner
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.
