Let's label all the valves.

So the valves at the bottom of those tubes there are like radio controlled airplane valves.

You have these valves come together we make it very clear, but making the two sides touch.

These are valves in our heart.

This is gonna happen on both sides, both ventricles and the valves shut.

You can kind of assume that, although the noise you're hearing is actually from here.

Just as I drew before and these valves snap shut as well. So now these snap shut.

These are the atrioventricular valves.

Keep your eye on the valves and we'll talk about them as the blood moves through.

To get the blood into those ventricles, the valves had to open.

When T and M snap shut, that makes a noise that we call lub.

So you have these valves keep the blood going in the right direction.

And to allow that, I need to show you, these open up. They allow the blood to go the way we want it to go.

Every time these valves go open and shut, you hear noise.

Open up three, five and seven oil valves.

Open the Diverter Valve and the Front Valve to allow water to flow.

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

Now, blood is gonna flow through those two valves. Similar to before, you could have some back flow here, right?

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

Finally, I have a thing for the keys on a flute or a clarinet.

So you have these valves. And you might get confused, because you think,

What you have to do is close the valves and check the filter.

We'll use those valves to talk through where those sounds are coming from.

You can imagine, let's say you have a little back flow that wants to go this way, which is the wrong direction, then these valves are gonna close up.

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.

Atrioventricular valves are the two valves between the atria and the ventricles.

But the veins have a different type of valves, and that's actually keep the blood flowing in the right direction.

And you can go inside the heart itself and repair the valves from the inside.

These valves shut down like that. You can see how the pulmonary and aortic valve are closed when the mitral and tricuspid valve are open.

Elsewhere, of course, this sort of turmoil has democratic safety valves.

You can imagine that you probably don't even need that on the arterial side, because the pressures are so high, that the blood is forced to go one way.

One of the things that keeps the blood flowing in the right direction is the valves.

You can take a guess as to which ones I'm referring to.

I heard my heart's valves snapping open and closed.

The main supplies for the production (Iron tubes, valves, cast iron items) are purchased in Ukraine.

He can go inside, push inside of the heart, and really feel how the valves are moving.

Schrader valves are also widely used in high pressure hydraulic systems on aircraft.

The valves are made up of two or three small but strong flaps of tissue called leaflets.

The atrioventricular valves, if you look at them, they're both kind of facing downwards.

The lemonade bottle should then be cut and flaps bent outwards to make the required number of sails.

Because of the possibility of the motion locking up, Zyablova valves were replaced with valves of the Celler type.

Water can kind of swirl around and around and around, and so it's helpful to have valves keeping going in the right direction.

These are particularly important for when you're trying to make sure that ventricles don't screw up the valves.

Insulation of the tank or a pressure relief valve do delay the time before a BLEVE would occur, but cannot definitely avoid a BLEVE.

What's happening between these two, time like here, is that blood is actually squeezing out because the pulmonic and aortic valves just opened, blood is squeezing out and going to the whole body.
