What comes to your mind with cardiovascular system

Cardiovascular

System

Organ system that carries
nutrients, gases and
hormones to the body cells
and waste products from
body cells.

Cardiovascular System

it’s made up of

The Heart

Blood Vessels

Blood

It is a special fluid primarily
contained within the blood vessels.

Serves as a transport system, providing supplies for
cells, carrying chemical messages, and removing wastes.

Travels trough miles and miles of blood vessels to reach
every cell in your body.

Blood

Our blood has four main components:

carry oxygen,
nutrients and wastes

fight diseases and
protect the body
from infection

straw-colored liquid
where the other
components float in

gather at the site of
injury and help the
clotting process

Red Blood Cells

White Blood Cells

Platelets

Plasma

15

Multiple Choice

What component of blood fights diseases and protects the body from infection.

• Red Blood Cells

• Platelets

• White Blood Cells

• Plasma

Blood Vessels

These are tubes or channels that
carry blood throughout our body.

There are three types of blood vessels
—veins, arteries and capillaries.
Each one differs in size and structure.

16

Carries blood away

from the heart

Remember ‘A’ for ‘artery’ and ‘away’ from the heart!

TIP

Blood Vessels

Each type of blood vessel has a unique role in the circulatory system.

Artery

Capillary

Assists in the exchange
of substances between
the blood and tissues

(body cells)

Vein

Carries blood back
towards the heart

17

Artery

Capillary

Vein

Blood Vessels

It has the thickest wall of all three, allowing it to
withstand the high pressure created by the heart. Also
has a layer of smooth muscle.

It has the thinnest wall to allow substances such as
oxygen and sugars to pass through its wall—into or out
of the blood.

It is less muscular and stretchy than an artery, so
blood moves through it with low pressure. It also has a
special valve that helps blood go only one way.

Let’s take a closer look at the three types of blood vessels:

The Heart

It works as a pump to move the
blood around the body.

When heart muscles contract, it
squeezes the blood inside the heart
to create pressure that pushes blood
trough the body.

19

The Heart

has a left side and a right side
separated by a thick wall.

20

Left Side

pumps
oxygen-rich
blood to the
body

Right Side

pumps
oxygen-poor
blood to the
lungs
