One of the wackiest things about the study of anatomy is how little we understand about the human body — even though we’re surrounded by bodies all day long. That said, there is plenty we do understand, and thanks to things like this biochemical pathways chart of our body’s chemical reactions, we can sorta kinda see what’s going on inside when we metabolize food. Amazingly, mind-blowingly cool! They need to come up with a chart detailing the biochemical pathways of falling in love, too. though that might be even more complicated. {Roche Applied Science via Corporeality}
