So you've already learned that the valves got endocardium.

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

And because of that, this cell won't be able to help the heart pump properly

First of all, heart failure is the number one reason for hospital admissions and readmissions in this country.

And when that happens that's called heart failure.

From the body... to the right auricle... to the right ventricle... and out the pulmonary arteries to the lungs.

I had to say goodbye in some way, shape or form.

So let's get started in the upper part of the heart. The Right atrium, It's right there.

And then it goes into the right ventricle.

So ischemia is deprivation of blood flow and oxygen downstream from this right over there.

4.8 million suffer cardiac failure.

And once the blood is in right atrium, it's going to head down into the right ventricle.

So I'm gonna just take some blue paint to indicate deoxygenated blood or blood without oxygen, I'm gonna paint in how it look.

I also want to once again differentiate cardiac arrest from heart failure, because they sound the same, sound like heart is failing.

Some plaques are actually unstable. These plaques just grow and grow and grow.

I was back in the hospital with some severely edemic kankles very attractive.

Today heart disease kills a quarter of the population in the western world the most violent form is the heart attack.

We're gonna start our journey here at the right ventricle. So what's the first thing that kind of comes across?

The first into the right atrium. This is chamber number one.

Incomplete

Neo penitentiary modern.

The answer is no, because what happens is that as blood is moving down from the atrium to the right ventricle,

lives, flipping certain individuals who've might otherwise be resistant to an infection.

So the blood from the arterial side is coming from the aorta and on the venous side it's actually not even dumping into the inferior or superior vena cava, kind of little known fact that is coming directly into the right atrium.

You really should lock your door.

It's incomplete.

I could hear crackly sounds on both sides that told me that she was in congestive heart failure.

Right hand, please. Incoming! He failed.

But now remember that blood is constantly moving through the heart, so in a previous cycle you actually had some blood that's coming back from the lungs and that's what's dumping into the left ventricle.

So you're probably feeling pretty comfortable with the diagram of the heart, but let me just go ahead and label a few things, just to make sure we're all on the same page.

We're gonna actually follow the path of blood after it leaves the right ventricle.

They'd been running that since 2008, and already have stopped cardiac arrests and distress within the hospital.

And it goes down into, you can probably guess how this one is called, is our left ventricle.

Insufficient Aliases

Diabetes, cancer, Parkinson's, Alzheimer's, heart failure, lung failure things that we know are debilitating diseases, for which there's relatively little that can be done.

Frankly, heart attack is not the only thing that can cause cardiac arrest.

It's abnormal to have the heart on the right side.

So when this guy is jogging, because he has restricted blood supply because the heart is experiencing ischemia downstream from this stenosis, that's why there's heart failure so not able to deliver

But once this is formed, this is called a blastocyst.

That's what we call coronary artery disease, or heart disease.

So heart disease is one of the causes of heart failure.

Let's start by labeling our heart, at the top, blood is coming into the right atrium, going to the right ventricle, it goes off to the lungs, comes back into the left atrium and then the left ventricle.

Restore incomplete.
