All right, So you're in AA Chapter 35. Problem for here. And we're looking at the long capillaries. And so just look at the anatomy. Right. This this is our our bronchial. So that smaller brown trait that breaks down into these smaller, far pieces here, the of Eli So sort of look like these little, boldest, boldest things here. Um, that's never be d viola I Okay. And then our capital a network. Right. So what is what is the purpose of these? Will we get blood flow from the heart sort of comes and wraps around, He's and I'm kind of connects, and then we get blood flow back out. Right? So this is like that. The oxygenated blood from the heart. So from the heart. And then we bring oxygenated blood to the heart. Okay, so and add some sort of capital areas. Fatso, these these old guys here, these veins, He's really small networks here that says there cappellini network on the lungs. Okay, so So what? That means, right is we're getting the blood with less oxygen and and sort of production in it. And so this this de oxygenated blood here, uh, carries a lot of co two, but mostly in the form of of this bicarbonate ion. Okay. And that's gonna combine with some of these free hydrogen ions, which are, uh, also to be located in and the hemoglobin. Then they add up nicely. Rex to eye on stand toe, like to go together. And this is gonna form, uh, this carbonic acid. Okay, so now we're starting to see some familiar terms that it's asking us about. So the carbonic acid. And what does that carbonic acid break down into? Well, this is actually gonna break down nicely into the into water and carbon dioxide. Okay, so this process here, uh, breaks down carbonic acid. So this this year is carbonic acid this age to CEO three into water and carbon access. So the correct answer here is C
