And these are called alveoli.

Let me draw these air sacs.

But the oxygen will come through our larynx, into our trachea, through the bronchi, eventually in bronchioles, ending up in alveoli and being able to be absorbed into what where the arteries, but then we're going to go back and then essentially oxygenate the blood.

Let me draw one right here.

It enters our body through the nose and mouth, moves down into the pharynx, trachea and bronchial tubes, and ultimately reaches the alveoli air sacs in the lungs.

So what's going to happen is that the air is flowing through the bronchioles and circulating around the alveoli, filling the alveoli and as they fill the alveoli, the little molecules of oxygen are allowed to cross the membrane of the alveoli and essentially be absorbed into the blood.

Other things will be coming in, but the O2 is what gets absorbed in the alveoli.

These cells cause disruption of the normal air spaces (alveoli) where oxygen is extracted from the atmosphere.

So if I were to zoom in on one of these alveoli and just to give you an idea, these are super duper duper small.

They run right past the alveoli and then they become oxygenated and now we're going back to the heart.

So going away from the heart to the lungs, to the alveoli, these are the pulmonary arteries.

And what we learned in the last few videos is that we have our little alveoli and our lungs.

In the gas phase, it can be used to image empty space such as cavities in a porous sample or alveoli in lungs.

But anyway, we have our little alveoli right there and then we have the capillaries.

To make sure the lung is satisfactory before transplanting the other a bronchoscopy is performed.

i In 1998 referred to as chronic or unspecified bronchitis and emphysema.

Then it goes to the heart, rubs up against some alveoli and then gets oxygenated and then it comes right back.

The infection of herbivores (and occasionally humans) by the inhalational route normally proceeds as follows Once the spores are inhaled, they are transported through the air passages into the tiny air sacs (alveoli) in the lungs.

It's in the loop with the lungs so it's a pulmonary vein and it rubbed up against the alveoli and got the oxygen diffused into it so it is oxygenated.

Once in the lungs, bacteria may invade the spaces between cells and between alveoli, where the macrophages and neutrophils (defensive white blood cells) attempt to inactivate the bacteria.

So you have these air sacs like this.

Lung volumes are directly measured Lung capacities are inferred from lung volumes.

Breathing 100 oxygen also eventually leads to collapse of the alveoli (atelectasis), while at the same partial pressure of oxygen the presence of significant partial pressures of inert gases, typically nitrogen, will prevent this effect.

And it goes over to the left lung, and over to the right lung.

So you have these vesicles.

literally snared the vesicles to this membrane.

They'll then be packaged in a little transport vesicle and moved to the Golgi apparatus.

This is the right lung and on this side you'd have the left lung.

He get pleurisy.

Windmills?

Why so? Because, in fact, the area of the lung is something very ill defined.

Could be a fat embolus in his lungs.

Maybe a bronchiole is terminating in another air sac just like that another set of air sacs just like that.

And then you have a bronchiole that's terminating in that air sac.

I'm going to tell you in a second how it gets squeezed.

When the surgeons are satisfied with the performance of the new lung, surgery on the second lung will proceed.

It literally means the arteries that are of the lungs or that go to the lungs and the veins that come from the lungs.

Now a lung is something very strange.

Left lung, wasn't it?

You can see the arrows pointing in the lung to a round lesion, which appears like a cystic lesion and this is actually a cavity.

Lung volume reduction surgery involves removing the parts of the lung most damaged by emphysema allowing the remaining, relatively good lung to expand and work better.

The alveoli use pressure to move oxygen and nutrients into the blood.

And they move material around, depending on what they do.

My father died of lung cancer.

Consider lung cancer.
