What is diffusion?
This molecule is the major stimulus for breathing.
What is CO2?

What is internal respiration?
These tubes founds in your nasopharynx help equalize pressure to your inner ear.
What are the Eustachian tubes
The right bronchus is more susceptible to aspiration due to these characteristics
It is wider, straighter, and more vertical
The alteration in your pH called this occurs during hyperventilation when you expel vast quantities of CO2.
What is respiratory alkalosis?
This accessory muscle aids in breathing by lifting attaching to the sternum and lifting the rib cage.
What is the sternocleidomastoid.
