Ahoy, young adventurers! I'm Captain Heart

Here's a little summary of my  job in the body!

My job is to pump blood all around your body. Blood carries oxygen and nutrients to your cells and picks up waste to get rid of it. I work all the time to keep you healthy and strong! So it's important you keep me healthy as well! 

Hey there! I'm Lenny and beside me is Larry. We're the lung twins!

Let's get into our role in your body!

Our job is to help you breathe. We take in oxygen from the air you breathe and send it into your blood. We also get rid of carbon dioxide, which your body doesn't need. Breathing keeps you full of energy! You're actually breathing right now!

What's up! I'm Danny the Digestive System! I have an important role too!

I help break down the food you eat into tiny pieces so your body can use it for energy, growth, and repair. I start working from the moment you take a bite, using organs like your stomach and intestines to do the job. Eating keeps you strong and healthy!

Great, now that you've met everyone let the journey begin...

Captain Heart’s Exciting Journey Through the Body...

.

Every day, Captain Heart navigates the winding highways of the arteries and veins, making sure every cell gets the oxygen and nutrients it needs.

Attention, crew! This is Captain Heart, ready to go a board on our exciting adventure through the body!

Arteries (red) and Veins (blue)

Captain Heart starts his adventure in the left ventricle, where he gives a big, powerful push! This sends the super speedy, oxygen-filled blood racing through the aorta, which is like the body's super-fast highway.

Let's go, team!

This is a more realistic picture of me!

Great job, everyone! Time to clean up and get ready for the next round!

When the cells are done using oxygen, it's time to head back! The blood, now carrying carbon dioxide and other waste, takes a trip back to Captain Heart through the veins.

Captain Heart’s Amazing Delivery Service:

Blood flow in the circulatory system is like a high-speed rollercoaster. "Sounds fun right? Haha I love my job!" Captain Heart says with a cheerful smile.

Oxygen-filled blood zooms out of Captain Heart through special tubes called arteries, delivering fresh oxygen to every cell. After the cells have used up the oxygen, the blood races back through the veins, bringing waste back to Captain Heart.

Captain Heart makes sure the ride is always smooth, so every cell gets the energy it needs to stay happy and healthy!

Here's Some Fun Facts About the Heart:

I'm quite interesting aren't I? Haha, well, kiddos, it’s time for me to pump off on another adventure! Remember, your heart is a superhero working hard every second to keep you strong and healthy. Keep moving, eat well, and stay heart-healthy! Until next time, stay pumpin!

And with that, Captain Heart zooms off, ready to continue his mission inside your amazing body. Stay tuned for our next adventure with Lenny and Larry, the dynamic duo responsible for helping us breathe!"

Psssst..

We're over here!

Lenny  & Larry the Lungs and the magic of breathing...

.

Hello! 

Hey!  Lenny and Larry the Lungs back at it again! We're here to show you how we breathe!

When you take a breath in, the air travels down the trachea and into my two big branches called bronchi.

Meet The Lung Twins! They're is here to show you how we breathe and how important oxygen is for our bodies.

Inside the lungs, there are tiny air sacs called alveoli. This is where the magic happens!

Oxygen from the air passes through the walls of the alveoli and enters your blood!

At the same time, carbon dioxide, a waste product, leaves the blood and enters the alveoli to be exhaled.

This way, your body gets the oxygen it needs and gets rid of carbon dioxide."

Psst.. CO2 is carbon dioxide and O2 is oxygen!

This picture shows the arrows showing the exchange of oxygen and carbon dioxide in the alveoli! So cool!
