Metabolism & Nutrition, Part 2: Crash Course A&P #37

Here’s a couple of words you might find useful in the study of human metabolism. They also happen to be two words that I enjoy in general. Brunch. Buffet. I’d throw in “all you can eat,” but that’s kind of implied, and then it would be six words, unless you hyphenate them. But still, brunch…
