Why Is Poop Brown And Pee Yellow?

The pigments in our food all get destroyed on their way through our digestive system...so where do the colors of our poop and pee come from?

FYI: We try to leave jargon out of our videos, but if you want to learn more about this topic, here are some keywords to get your googling started:
- Red blood cells (RBCs), also called erythrocytes, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen
- Hemoglobin also spelled haemoglobin and abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells of all vertebrates as well as the tissues of some invertebrates.
- Bilirubin is a yellow compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates.
- Urobilinogen is a colourless by-product of bilirubin reduction. It is formed in the intestines by bacterial action on bilirubin. About half of the urobilinogen formed is reabsorbed and taken up via the portal vein to the liver, enters circulation and is excreted by the kidney.
- Urobilin or urochrome is the chemical primarily responsible for the yellow color of urine.
- Stercobilin is the chemical responsible for the brown color of human feces"

Have you guys written any biology-, physiology-, or waste-related "roses are red" poems we should know about?

[besmart]

(Minute)earthy tones like yellow and brown never go out of style

[jazzylps]

Roses are red
Violets are red
Trees are red
My garden is on fire

[arooobine]

Roses are red
Violets are blue
The first line's obvious
The second's not true

[APS]

That poem will genuinely save the future prospects of many students stressed with exams for the rest of their lives. It's so simple yet effective and informative

I'm now on the toilet watching coincidence ? I think not

This is the quality content I want to see

Then how come the more hydrated you are the less yellow it is

When it’s 3 am and the featured video on YouTube is why is poop brown and pee yellow:

I don’t need sleep. I need answers

I kept hearing bilirubin as though it were a name: Billy Reuben. (I just think it's a weird coincidence.)

This question is now crossed off my bucket list. Thanks.

[beepbeep]

Roses are red
Violets are blue
Bilyruben is stuck in an infinite loop

[shimrsparklshine]

How coincidental- I was pondering this question yesterday! Now I know! This video was very informative and I love the animation!

"Always remember to let it mellow" What the heck does that mean?
