Pulseling — Breathing & Circulation Heartbeat Rapids

Hi!

I'm Pulseling.

Welcome to Heartbeat Rapids!

Will you help me investigate breathing & circulation?

The Grumblies have mixed up our clues.

Let's check the evidence!

Lungs exchange gases with blood: oxygen enters the blood

and carbon dioxide leaves it.

Breathing moves air into and out of the lungs.

Where does oxygen from air enter the blood?

  • A. At the lungs
  • B. Inside a bone joint
  • C. Only the stomach

The answer is A: At the lungs

Lungs exchange gases with blood: oxygen enters the blood

and carbon dioxide leaves it.

Breathing moves air into and out of the lungs.

That clue helps us make sense of this place.

The heart pumps blood through vessels.

Blood carries oxygen and other materials to body parts

and returns materials for removal.

Which organ pumps blood?

  • A. The stomach
  • B. The brain instead of the heart
  • C. The heart

(In Breathing & Circulation.)

  • A. The stomach
  • B. The brain instead of the heart
  • C. The heart

The answer is C: The heart

The heart pumps blood through vessels.

Blood carries oxygen and other materials to body parts

and returns materials for removal.

Hmm...

how does that connect to our first clue?

Our broad route is air to lungs, oxygen into blood,

then transport around the body.

Lungs and circulation cooperate rather than each doing the whole job alone.

Which route fits our model?

  • A. Air, skull, solid stone
  • B. Air, lungs, blood, body parts
  • C. Air directly becomes solid bone

The answer is B: Air, lungs, blood, body parts

Our broad route is air to lungs, oxygen into blood,

then transport around the body.

Lungs and circulation cooperate rather than each doing the whole job alone.

Nice investigating!
