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

  • Hey, Nerb.

  • I got here as soon as I could.

  • Where are we going today?

  • And why am I dressed like an old timey hobo?

  • Isn't it obvious?

  • We're going to learn about the endocrine system.

  • Yeah, that still make no sense.

  • The glands of the endocrine system

  • deliver chemicals called hormones

  • to various parts of your body.

  • They regulate the processes of your body

  • and make sure all the hormones get where

  • they need to go, on schedule.

  • And what else runs on schedule and delivers important goods?

  • Trains.

  • Nerb, are we going to ride the endocrine rail?

  • Oh, I've always wanted to.

  • Even better Chloe.

  • Uh oh.

  • We're riding the rails, all right.

  • But not in a train.

  • No ma'am.

  • We're taking this rusty old handcar.

  • Joy.

  • Each gland of the endocrine system

  • produces chemicals called hormones.

  • And each hormone has a different job.

  • The glands are spread out through the body.

  • A lot of them are controlled by a little gland

  • near the base of your brain, called the pituitary.

  • Thyroid, increase production.

  • Attention, ovaries, let's get the estrogen rolling.

  • I've got my own work to do here too.

  • Growth hormone, coming up.

  • This guys in charge of the entire endocrine system?

  • This guy's tiny.

  • Who are you calling tiny, skinny arms?

  • I may be small, but I'm what makes you big.

  • It's true, Chloe.

  • The pituitary gland produces growth hormone,

  • which is what makes you grow big and tall.

  • And as you can tell, he's used to giving orders.

  • I should be.

  • I'm pretty important.

  • Even though the pancreas makes insulin and the nervous system

  • handles adrenaline, I am still vital endocrine wise.

  • Now scram.

  • I'm busy.

  • I hope our next gland is friendlier.

  • Are all those trains hormones?

  • They sure are.

  • They're my thyroid hormones.

  • That makes you the thyroid.

  • Right again.

  • My hormones do a number of jobs.

  • But one of the most important ones

  • is regulating how fast your body uses the calories

  • from the food you eat.

  • That's called metabolism.

  • Fancy word.

  • Next stop, the adrenal glands.

  • This should be exciting.

  • Hold on.

  • I thought the adrenal glands were

  • in charge of handling danger, and excitement, and fun

  • stuff like that.

  • These guys aren't doing anything at all.

  • Hey, you lazy glands.

  • Wake up.

  • Why?

  • We're napping here.

  • Don't you think you should be doing your job?

  • This is our job.

  • Listen, sister.

  • The hormone we make is called adrenaline.

  • And it's very powerful stuff.

  • Only to be used in case of emergency.

  • Is there an emergency?

  • No.

  • In that case, quick behind you, huge angry bear.

  • And that my friend is the power of adrenaline.

  • Wee-haw.

  • Those rascally glands.

  • But look how far we came.

  • We thought we were in danger.

  • So our powerful adrenalin kicked in

  • and took us almost all the way to the next gland

  • in two seconds flat.

  • What is that bit lump over there?

  • This big lump is the pancreas.

  • I'm the biggest gland of the endocrine system.

  • You certainly are.

  • So what do you do lump?

  • Pancreas.

  • I produce insulin.

  • It's the chemical that helps you use energy

  • from the food you eat.

  • One last question, lump.

  • Pancreas, and yes?

  • Can I jump on you?

  • Go ahead.

  • Welcome to the final glands of the endocrine system.

  • The reproductive glands, one of the most important things

  • they do is make sure your body goes

  • through the changes of puberty.

  • So you can grow from a child to an adult.

  • I'm the ovaries.

  • I oversee puberty in girls and excrete

  • a hormone called estrogen.

  • And I'm the testes.

  • I do the same for boys.

  • My hormone is called testosterone.

  • Think of us like sports team coaches.

  • I coach the girls' team.

  • He coaches the boys' team.

  • Go, boys.

  • Girls rule.

  • After a long day of pumping adrenaline and pumping

  • a handcar, it feels great to kick back and relax.

  • To the endocrine system, may it always stay on track.
