Introduction
• The cardiovascular
system is one of the
major body systems
that makes sure that
the muscles and bones
are supplied with the
proper amount of
oxygen and blood.
Why is it important?
• The cardiovascular system is important because it
carries all of the oxygen, nutrients, hormones, etc to
the cells and carries away all the toxins and carbon
dioxide away from the cells. Cardiovascular disease is
the leading cause of death in the United States.
Without the cardiovascular system's functions, we
would die in a matter of minutes (in fact, for humans,
death is determined by when the heart stops beating).
Organs
• The main
organs are the
heart, arteries,
veins,
capillaries, and
the blood..
Heart
• The heart is a muscular coneshaped organ about the size of
a clenched fist of the same
person.
It is located in the upper body
(chest area) between the lungs,
and with its pointed end (called
the apex) downwards,
forwards, and pointing towards
the left.
The main purpose of the heart
is to pump blood around the
body.
Arteries
• The heart pumps blood
out through one main
artery called the dorsal
aorta. The main artery
then divides and
branches out into many
smaller arteries so that
each region of your body
has its own system of
arteries supplying it with
fresh, oxygen-rich blood.
Veins
• A vein is an elastic blood
vessel that transports
blood from various
regions of the body to the
heart. Veins can be
categorized into four main
types: pulmonary,
systemic, superficial, and
deep veins.
Capillaries
• A capillary is an
extremely small blood
vessel located within the
tissues of the body, that
transports blood from
arteries to veins.
Capillaries are most
abundant in tissues and
organs that are
metabolically active. For
example, muscle tissues
and the kidneys have a
greater amount of
capillary networks than
do connective tissue.
The Lungs
• The lung is a magnificent
organ that performs a
multitude of vital functions
every second of our lives.
Breathing is the most
essential of these
functions. With each
breath, the lungs take in
oxygen and remove
carbon dioxide
