I realize that it looks little bit scary. But, once I start labeling these stuff you'll start to see that it is actually not as bad as it seems.

We have a hot detective.

We can also know who's likely to get atrial fibrillation.

So this is the right ventricle, down here.

Then, look at that after three minutes.

He died quite suddenly of heart failure.

Within five weeks, you start to see the early atrium and the early ventricles.

We'll take a look at its brains.

And today we can obtain cells from most every organ in your body, except for several which we still need stem cells for,

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

But if we look on other parts of our bodies where we don't directly interact with the environment our kidneys, our livers, our hearts there is no way to say, by just looking at these organs, where in the world they would come from.

And then we put a lead, which is a wire, in the right ventricle inside the heart, which does the electrogram, which is the signal voltage from inside the heart.

Then he can examine how the heart is moving.

So you can see how blood now flows from the body into the four chambers.

This is all done in between the ribs.

Feel my heart.

Fright gave the old lady heart failure.

We call this the biomimetic paradigm copying nature in the lab.

The beating heart of Rome is not the marble of the Senate.

And this valve and all valves in the heart are basically there to keep blood moving in the right direction.

Then he can examine how the heart is moving.

He might need surgery

What's the matter with him?

Now that heart.

My heart!

My heart.

Man is part of nature.

Some of them show greater variability.

An iPatch, iRhythm, for atrial fibrillation.

How can over 100 people have heart attacks at the same time? !

So it's not pumping hard enough or well enough to provide adequate function for that person.

How 'bout you?

Is it a heart attack?

Feel her heart beat.

Obviously this isn't drawn to scale.

Your partner, he's had a heart attack.

Looks like he died of natural causes. Maybe a heart attack.

It's her heart.

(HEART MONITOR BEEPING)

(HEART MONITOR FLATLINING)

Heart attack.

I thought my heart was gonna explode.

This is the posterior part, where his muscles are going to be moving, and he's going to be pacing himself.

And suddenly, my heart's pounding so loud I can't hear anything else.

And when your heart stops beating... so will the baby's.
