Up here you have the pulmonary valve.

So just like before where we went from the right atrium to the right vertricle, now we're going from the left atrium to the left ventricle.

You can take a guess as to which ones I'm referring to. Atrioventricular valves are the two valves between the atria and the ventricles.

When the valves snap shut, for example the tricuspid and the mitral valve snap shut, well, that makes a noise.

You'll hear S1 when the tricuspid and the mitral valve snap shut. So far so good.

These valves shut down like that.

No surprise, just as before, if that's S1, this is S2.

Just to orientate us this is the tricuspid (T) and this is our mitral (M).

So when you have dub, you have noise coming from the pulmonic and the aortic valve snapping shut.

18.Rare diseases

But you also know that if that is what's making the noise, you can kind of guess, and it's a smart guess that at the same time the pulmonic and the aortic valve just opened.

As the blood is now in the ventricles, you can see that the tricuspid and the mitral valve are open.

No heart disease, nocturnal asthma or sleep apnea.

I'll show you an example of that real quickly.

When I travel around, I ask my colleagues in biomedical research

I feel like i'm going clinically insane.

If the ventricles are squeezing, there's a good chance the blood is gonna shoot up in any direction it can go.
