And then right here is your larynx.

And the larynx is also our voicebox.

And I'm going to concern ourselves with the larynx.

My tongue, larynx and vocal cords were still healthy and unaffected.

So I'm going to focus as the air goes through our larynx.

Most laryngeal cancers in the UK are glottic, meaning they start in the vocal cords within the larynx.

He had to undergo Larynx surgery on March 30 to remove a cyst that had formed on his vocal cords.

Now, what I mean by echolocation they emit a sound from their larynx out through their mouth or through their nose.

Do you think I am ever caught napping at such an hour, and that I have not got lungs and a larynx as well as yourself?

But then after the air passes through the larynx this is on the way in it goes to the trachea, which is essentially just the pipe for air.

As a part of the vagus nerve, it comes from the brain, passes through the neck down to heart, rounds the dorsal aorta and returns up to the larynx, again through the neck.

Smoking is a major risk factor for heart attacks, strokes, chronic obstructive pulmonary disease (COPD) (including emphysema and chronic bronchitis), and cancer (particularly lung cancer, cancers of the larynx and mouth, and pancreatic cancer).

Remember, we get to them from our bronchioles, which are branching off of the bronchi, which branch off of the trachea, which connects to our larynx, which connects to our pharynx, which connects to our mouth and nose.

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.
