  • KidsHealth presents "How the Body Works,"

  • with Chloe and the Nurb.

  • [MUSIC PLAYING]

  • [PANTING]

  • [MUSIC PLAYING]

  • [ANGELIC CHOIR]

  • [PANTING]

  • [DING]

  • No!

  • Hello there, Nurb.

  • Chloe?

  • What are you doing up there?

  • Looking for a learning adventure.

  • OK!

  • Good luck!

  • Hope you find a good one!

  • Oh, I already have.

  • Tell me, Nurb, what do you know about the urinary system?

  • Way.

  • Too.

  • Much.

  • Ha!

  • No, seriously.

  • What do you know?

  • Uh, there's some bean-shaped things and maybe some tubes?

  • Precisely.

  • And also imprecisely.

  • You see, the urinary tract begins at the kidneys, which

  • are the two bean-shaped things.

  • The kidneys are organs the size of your fist

  • that sit under your ribs along your back.

  • Kidneys filter blood to remove waste.

  • That waste and extra water combine

  • to make urine, which is also called pee!

  • Um, Chloe?

  • After the kidneys, it's pretty much just plumbing.

  • The urine enters two small tubes,

  • one coming from each kidney.

  • Chloe--

  • Those are called the ureters.

  • They lead to the bladder.

  • The bladder is a sack that holds the pee.

  • Chloe!

  • Right now, your bladder is probably

  • feeling very full, since you look really

  • stressed out about it.

  • When it's time to go to the bathroom,

  • the smooth muscle of the bladder contracts

  • to push pee into another tube called

  • the urethra, which carries the pee out of the body.

  • Chloe, you know that typically I'd

  • love to learn anything, anything about the human body.

  • But right now-- right now, I think

  • I'd really prefer to talk about anything, anything but pee.

  • Oh.

  • I'm sorry, Nurb.

  • I didn't mean to make you uncomfortable.

  • [GULPING WATER]

  • [MUSIC PLAYING]

  • It's just that staying hydrated is incredibly important to keep

  • the human body running well.

  • Fluids of all kinds help keep us hydrated,

  • but nothing does it as well as water.

  • Ah yes, tell me more about water, Chloe.

  • Our bodies are actually made of water.

  • 60% of our body mass is just water.

  • Have another sip, Chloe.

  • Talk to me about hydration.

  • We feel better and even think better

  • when we drink enough water, plus it's delicious and refreshing.

  • Drinking water keeps you from getting dehydrated-- that's

  • when you don't drink enough water

  • and you feel dizzy and sick.

  • How is that water, Chloe?

  • It's great!

  • I feel very hydrated.

  • [SLURPING]

  • Did you know that you can tell if you've drunk enough water

  • by the color of your pee?

  • If you're well-hydrated, your pee

  • will be light yellow because your body has plenty

  • of extra water to get rid of.

  • If your dehydrated, your pee may be a darker yellow

  • because your body is holding on to the water

  • instead of peeing it out.

  • Have you had enough water, Chloe?

  • [SIPPING]

  • Yeah, I think I have.

  • And now we wait.

  • Aah!

  • I have to pee!

  • Get in line, sister.

  • It's gonna be a wait.

  • But I can't wait.

  • I just drank this whole bottle of water.

  • What could possibly be going on in there?

  • Just take a deep breath and think

  • of all those happily-hydrated cells sloshing around

  • in your body, full of all that water you just drank.

  • That's it.

  • I'm busting in there.

  • [DRUMROLL]

  • [MUSIC PLAYING]

  • [SNORING]

  • Grampa Jebediah Nurb?

  • Eh?

  • Who's that?

  • I'm, I'm trying to nap here.

  • Nap?

  • Nap?

  • I've been waiting all this time and you've been napping?

  • It's the only place to grab some peace and quiet around here.

  • Excuse me, Grampa Nurb, but do you think you could let us pee?

  • Yeah, yeah, keep your pants on.

  • You know what they say-- ladies first.

  • Oh no, that's what humans say.

  • In Nurbish, the saying goes, uh, "He

  • who shows up first to urinate is allowed

  • to be the first to urinate."

  • Ha ha.

  • Oh, come on, you just made that up.

  • Noooo!
