  • KidsHealth presents How The Body Works with Chloe and the Nurb.

  • [SINGING] Oh, the tibia's connected to the femur.

  • The femur's connected to the ilium.

  • Ooh, hello there, Chloe.

  • Nurb.

  • Where are you?

  • I'm the gelatinous blob lying on this rock.

  • Oh.

  • Nurb, where are your bones?

  • Being cleaned, of course.

  • Once a year, we Nurbs send our bones out

  • for some serious scrubbing.

  • And today's my bone-cleaning day.

  • Well, technically yesterday was my bone-cleaning day.

  • The cleaning service temporarily misplaced my bones.

  • At least they found my skull.

  • [SINGING] The fibula's connected to the tibia.

  • The--

  • I wish I could help you, but I don't know anything

  • about bones.

  • Tut.

  • Don't know about bones.

  • Don't know about bones!

  • Do you like to talk?

  • Eat?

  • Swim?

  • Dance?

  • Like my dance?

  • It's great.

  • And yet I like all those things.

  • Then you need to know about bones.

  • Or as they're known to fancy people, the skeletal system.

  • And there's only one place for us

  • to go to learn about the bones.

  • The Boneyard.

  • As creepy and awesome as that sounds,

  • how are you going anywhere?

  • Simple-- strap me on like a backpack.

  • I should have known.

  • All right, Jelly Nurb.

  • Let's do this thing.

  • Bone lesson number one-- the bones have three main jobs.

  • They allow your body to move, they

  • protect your delicate vital organs,

  • and they produce blood cells in bone marrow.

  • Speaking of moving, I have to say,

  • you are surprisingly comfortable to wear.

  • Why, thank you, Chloe.

  • I get that a lot.

  • Bone lesson number two-- bones are made of calcium.

  • And when you consume calcium-rich foods, like milk,

  • your bones are very happy things.

  • Ooh, Nurb, look.

  • The Boneyard.

  • [SINISTER LAUGHTER]

  • Well, this isn't exactly what I expected.

  • I told you, bones are happy things.

  • Press me on that lovely rock over there

  • and I'll teach you about bones and help you

  • through the skeleton-building process.

  • The what-building process?

  • We're here to build me a temporary skeleton, of course.

  • That sounds surprisingly fun.

  • Direct away.

  • Great attitude, Chloe.

  • High five.

  • Aw.

  • Take this blueprint and off you go.

  • And don't worry, it only takes 206 bones to make a skeleton.

  • Challenge accepted.

  • Now there are two different kinds of bones.

  • There are axial bones they keep you upright,

  • like ribs in the spine.

  • And appendicular bones that help you move,

  • like the bones of your arms and legs.

  • Axial and appendicular.

  • Correct.

  • And that thing that lets the leg move back and forth is a joint.

  • Joints connect bones to help them move.

  • That one's a knee joint.

  • Woah, Nurb.

  • What's this bone?

  • It's tiny.

  • That, my dear Chloe, is one of the ossicles.

  • There are three of them in your middle ear

  • and they're the smallest bones in your body.

  • So I have to find two more?

  • Game on.

  • Chloe, if I could applaud your adventurous spirit right now,

  • I would.

  • But unfortunately, there are no bones in my hands.

  • Ooh, this one's got a crack in it.

  • That is called a fracture.

  • Bones fracture, or break, all kinds of ways.

  • Sometimes they're very small breaks,

  • like hairline fractures.

  • But sometimes, the fracture can be more serious.

  • Yikes.

  • Don't worry, bones are living things.

  • And they fix themselves pretty quickly.

  • New bone cells grow on the broken ends

  • to fuse the two parts together again.

  • Sometimes you need a cast to keep

  • the pieces of the bone in place so they grow back correctly.

  • I think this baby is done.

  • How does it look?

  • Oh, Chloe.

  • It's beautiful.

  • Try it on.

  • Wow, you look great.

  • You think so?

  • I've never been so tall.

  • It might be a little hard to walk.

  • I think I may have an idea.

  • [SINGING] The ilium's connected to the spinal column.

  • The spinal column's connected to the rib bones.

  • The rib bone's connected to the--
