throughout body
 Heart is made up of 4
chambers
 two on top – left and right
atriums (receive blood
from lungs and body)
 two on bottom – left and
right ventricles (push blood
out to body and lungs)
 septum is a thick wall of
muscle that separates the
right and left side.
 valve lets something in and
keeps it there by closing

Respiratory systemexchanges gases in
lungs.

Digestive system delivers nutrients to
cells in body and
takes waste away.
INTERESTING FACTS
How does the heart beat? Before each beat, your
heart fills with blood. Then its muscle contracts to
squirt the blood along. When the heart contracts, it
squeezes — try squeezing your hand into a fist. That's
sort of like what your heart does so it can squirt out
the blood. Your heart does this all day and all night, all
the time. The heart is one hard worker!
Remember that your heart is a muscle. If you want it
to be strong, you need to exercise it.
Your heart doesn't look like a valentine.

Veins (blue)

Arteries (red)

capillaries
tubes that go
throughout the body

reach every part of
the body

support all systems

transport blood.

Veins - carry blood back to
the heart to get
oxygen/exchange CO2

Have valves that make
sure blood moves the right
direction

Arteries carry blood away
from heart with oxygen for
body

Elasticity – arteries are thicker than veins.
Blood leaving the heart is under more
pressure to move throughout the body.

Cholesterol – plaque can build up and clog
arteries. It’s important to eat a variety of
healthy foods and avoid foods high in
unhealthy fats, such as saturated fats and
trans fats (reading the labels on foods can help
you figure out if your favorite snacks contain
these unhealthy ingredients)

It takes less than 60 seconds to pump blood
to every cell in your body

You can feel your pulse in your wrist
