Oh, wow, oh, oh, wow, oh, wow, oh, wow.

Oh, wow.

Oh, my. Hello, you're listening to The Science of Everything podcast episode 123 respiratory and circulatory

systems part two. I'm your host, James Fodor. This episode is, unsurprisingly, a direct

continuation of the previous episode, 122 respiratory and circulatory systems part one, which is a prerequisite.

And in this episode, we're going to pick up from where we left

off there and talk about the role of blood and how it transports oxygen and other nutrients

and wastes around the body. We're going to look at blood pressure, oxygen dissociation curves,

blood types, and a bit about the lymphatic system. We're then going to talk about the respiratory

system and talk about where blood gets its oxygen from

and how oxygen and carbon dioxide are exchanged in the lungs and the process of breathing,

as well as control of respiration and a little bit about adaptations to breathing in high altitudes.

Before we get into that, however, there are a couple of announcements about the show.

So some of you may have noticed previous episodes appearing in the feed.

And I mentioned this in the end of the past episode, but for those of you may have missed that or forgotten,

the reason for this is because certain aggregator sites do not allow MP4, sorry, they do not

not our M4A files to be played or distributed.

And some of my early episodes are in M4A format for some strange reason that I don't understand.

So the only way that I've figured out around that is to re-upload them as MP3s.

And unfortunately, I can't put them earlier in the feed.

So they just appear, you know, as most recent items in the feed.

So that's why you're seeing those there.
