How Does Blood Flow and Pressure Work in the Human Heart?

[dhbeno]

I have a school assignment about the physics of the human heart, primarily about the pressures in the ventricles and atriums, what causes the valves to open and what makes blood flow from the atrium to the ventricle, what is the pressure and where? I already know how what makes the heart beat (from the electrical point of view) Does anyone know more about this topic? Thank you! :)

Shouldn't you being doing some attempt at research on the topic? If so, what have you already found? Do you find that there is a particular aspect of the workings of the heart from your research that begs a particular question?

The valves between atrium and ventricles are called atrio-ventricular valves. They can only open to one side,that is, towards the ventricle side. So when the blood flow from atria to ventricle,the valve is open.When it tries to flow from ventricle to atria,it get's closed. There are thousands of images out there.
Ventricles contract to make pressure. As you know, pressure is inversely proportional to volume. As the volume decreases,pressure increases.

Sharing the links which may help you get correct information and you will be able to know about the pressures in the ventricles and atriums, what causes the valves to open and what makes blood flow from the atrium to the ventricle, what is the pressure and where?

Let me know if you have any doubt.
