Why is poop brown? Bet that question has been dogging mankind for centuries. For a mere $20,000 in first year's medical school tuition money, you can get your answer. The more budget-oriented answer seekers may always turn to Google. Wonder where Encyclopaedia Brittanica falls in this spectrum of knowledge authority...
Anyways, the answer is bilirubin, which, to make the long story short, is the end product of hemoglobin breakdown. Along the way, it ends up being slightly modified, excreted with bile into the gut, and voila, there's brown poo. Now back to studying.
For obvious reasons, no picture with today's blog.
