4. Pieces and Parts Heart Lungs Your heart is an organ in your chest,
a little to the left of your breastbone. It’s the size of your fist.
Your heart pumps your blood through your body. It has 4 chambers that pump the blood.
Lungs
Your lungs are organs in your chest,
inside your rib cage.
Your lungs are what make you breathe.
They take in oxygen from the air you breathe in (inhale) and release carbon dioxide when you breathe out (exhale).

6. Pieces and Parts Blood Your blood flows to every part
of your body bringing oxygen,
and nutrients to your body.
Blood is made up of 4 parts:
Plasma: the clear part of blood that everything floats around in
White blood cells: the cells that fight germs
Red blood cells: the cells that bring oxygen to your body and takes carbon dioxide away
Platelets: the cells that clot your blood when you get a cut and make a scab

7. Pieces and Parts
Scabs
Your scabs are formed by the platelets in your blood.
They stick together with fibrinogen and make a web that covers your cut.
Scabs protect you from germs that could get in through your cut.
Don’t pick your scabs,
they are your body’s
protection against germs!

13. Science Knowledge You can see how your heart is working!
Find your pulse on the side of your neck.
Be still, and count how many times your hear beats in 6 seconds. Then add a zero to that number and that is how many times your heart beats in one minute.
Now, run IN PLACE for one minute.
Take your pulse again for 6 seconds
and add the zero! (multiply by 10)
Did your heart beat faster?
Exercise is good for your heart,
it makes it stronger!
