Circulatory
System
By: Audrey
Each breath you take brings air into your
lungs. That air is needed by the trillions of
cells in your body. Your heart is essential
in delivering that oxygen. It’s beating
produces the force to move oxygen rich
blood threw the circulatory system.
Function
• Brings oxygen, nutrients, and
hormones to cells.
• Fights infections
• Regulates body temperatures
Structures
• Heart
• Arteries
• Veins
Heart
Arteries
• Arteries carry mostly
oxygenated blood
away from the heart
to the tissue and
organs in the body
Veins
• The Veins are
responsible for the
transportation of
deoxygenated blood
back to the heart.
Diseases
• High blood pressure
• Heart attack
• Stroke
High Blood
Pressure
• Forces the heart to
work harder, which
may weaken or
damage the heart
mussels and blood
vessels.
Heart Attack
• Coronary arteries, a
set of arteries that
bring oxygen and
nutrients to the heart.
If one of these
arteries becomes
blocked, part of the
heart may begin to
die due to lack of
oxygen.
Stroke
• Blood clots break
free and gets stuck
in one of the blood
vessels leading to
the brain.
Blood Types
• If two different blood types are mixed together,
the blood cells may begin to clump together in
the blood vessels, causing a potentially fatal
situation. Therefore, it is important that blood
types be matched before blood transfusions take
place. In an emergency, type O blood can be
given because it is most likely to be accepted by
all blood types.
Donating Blood
• A person with type A
blood can donate blood to
a person with type A or
type AB. A person with
type B blood can donate
blood to a person with
type B or type AB. A
person with type AB
blood can donate blood to
a person with type AB
only. A person with type O
blood can donate to
anyone.
Receiving Blood
• A person with type A blood can receive
blood from a person with type A or type
O. A person with type B blood can
receive blood from a person with type
B or type O. A person with type AB
blood can receive blood from anyone. A
person with type O blood can receive
blood from a person with type O.
