Oxygen Hemoglobin Dissociation Curve is the topic du jour, and I am going to do my best for you to not get bored. Well, welcome to another MedCram lecture. We’re going to talk about the effect of different things on the oxygen hemoglobin dissociation curve. So we’ve got a red blood cell that kind of…

Instead, you get all of your oxygen the way that your oldest, smallest evolutionary ancestors did — by simple diffusion.
microbial life: They did so on a planet that had been home to all these organisms for billions of years. This is Ed Yong, he’s written a book about the microorganisms that live inside us and all around us.
Microbiology Crash Course, History of Science #24: What makes beer? Single-celled organisms. What makes us cough and feel like sleeping for twelve straight hours Straight? Single-celled organisms; AKA microbes, germs, the tiny machines that allow us to digest—and can kill us. “What is life?” It turns out, life is relentless, everywhere on earth! Microbes are…
Microbiology, a brief history part 2: He hypothesized that microbes are everywhere and must be responsible for all kinds of phenomena, like making food spoil.
