Welcome to the MCAT basics podcast, brought to you by the physicians at med school coach.

Each week, Sam Smith breaks down high-yield MCAT topics, so you can score as high as possible on test day. Welcome to MCAT basics. I'm Sam Smith,

and this episode covers the respiratory system. I'm first going to get into a little bit of anatomy

related to the respiratory system. Then I'll talk about the several different functions

that the respiratory system serves. Number one, that's gas. Then I'll talk about the several different functions that

the respiratory system serves. Number one, that's gas exchange. I'll talk about number two,

thermal regulation, three, particle filtration, and fourth, I'll talk briefly about pH control.

And then the very last thing I'll talk about in this podcast is how the respiratory system is

controlled. Now, this material is how the respiratory system is controlled.

Now this material is going to show up on two of the MCAT sections.

You get a little two-for-one action here.

The first section is bio-biocam and the second is chem-fiz.

And you might be asking, wait, chem-fiz, where does that come up in the respiratory system?

Well, as you'll see, I get into a

little bit of physics and chemistry here as I talk about gas exchange and the movement of gases

through the lungs. So with all that said, I hope this helps in your studies, and good luck to those

of you who are taking the test soon. Okay, so the very first thing I want to get into here is just some general anatomy related

to the respiratory system. And as with all anatomy on the MCAT, I always start out by saying
