because learning about the heart helps children understand how the body stays alive and active.
The heart is a strong muscle about the size of your fist. Its main job is to pump blood all around the body.
What does the heart do?
The heart:
-
Pumps blood to every part of the body
-
Sends oxygen and nutrients to cells
-
Removes waste like carbon dioxide
-
Keeps organs working properly
Blood travels through special tubes called blood vessels — arteries, veins and tiny capillaries.
How the heart beats
Each heartbeat has two main actions:
-
Pump: Blood is pushed out to the body
-
Relax: The heart fills with blood again
This repeating action creates the heartbeat we can feel in our chest or wrist.
An average child’s heart beats about 80–100 times per minute!
Why exercise is good for the heart
Activities like running, cycling and playing sports:
-
Make the heart stronger
-
Help blood flow better
-
Keep energy levels high
That’s why doctors say active kids usually have healthier hearts.
What keeps the heart healthy
Healthy heart habits include:
-
