Structure and Function of
the Cardiovascular System
Made up of the heart, blood, and miles of
blood vessels
Closed system.
Moves oxygen and nutrients to cells
Removes carbon dioxide and wastes
The Heart: The Beat
Goes On!
Made of cardiac muscle that never stops
moving
Located behind your sternum and
between lungs
Keeps blood moving throughout your
body
Diagram of the Heart
Blood
Tissue consisting of cells, cell
fragments, and liquid
Carries oxygen from the lungs to all
body cells
Removes carbon dioxide and carries it
to the lungs to be exhaled
Carries waste products to the kidneys
to be dispelled
What’s in Blood
Blood is composed of plasma, red blood
cells, white blood cells, and platelets.
Plasma
Red Blood Cells
White Blood Cells
Platelets

Plasma
Plasma makes up 75% of blood. It is made up mostly of water.

Red Blood Cells
Red blood cells are very important. Their job is to carry oxygen
throughout the body and to pick up and get rid of carbon dioxide.

White Blood Cells
White blood cells help the body fight disease.

Platelets
Platelets are irregular shaped cells. They help blood clot when a
person gets injured.

3 Types of Blood Vessels
Arteries: Move oxygen rich blood away
from the heart
Veins: Move non-oxygenated blood back
to the heart
Capillaries: Microscopic blood vessels that
connect arteries and veins
Mapping the Path
The blue lines show
blood rich with oxygen
flowing away from the
heart.
The red lines show blood
that is going back to the
lungs to pick up more
oxygen.
What do you know?
What is the purpose of the cardiovascular
system?
Why do you need blood circulating
through your body?
When does the heart rest?
Why are capillaries so tiny?
