Parts of the Circulatory System
► The
Heart - is divided into FOUR Chambers
Three Kinds of Blood Vessels
► Arteries
– Carries blood away from the heart
► Veins – Carries blood back to the heart
► Capillaries – Delivers low-oxygen blood to
veins (Smallest)
Two types of Arteries
►
Arteries start with A takes
blood away !!
►
Aorta – Largest blood
vessel in the heart
►
Pulmonary Artery – Carries
blood containing carbon
dioxide from your heart to
your lungs
Parts of the Blood
►
Red Blood Cells – Made in
bone marrow; carries oxygen,
food, and rids body of CO2 and
waste
►
White Blood Cells – Help fight
disease and infection by
destroying bacteria and germs
that enter the body. Made in the
lymph nodes
Parts of the Blood
► Platelets
– Help
blood to clot, to
prevent excess
bleeding.
► Plasma
– Water
portion of the blood;
55% of blood is
plasma

Body contains 4-6 L

Blood Disorders
Blood Pressure:
(Hypertension)
The force or pressure
developed by the heart,
which acts to pump blood
through the circulatory
system.
Blood Pressure
►
Sphygmomanometer:
An instrument used to
measure blood pressure.
►
Stethoscope: An
instrument used to listen
to the sounds of the heart,
or listen to the flow of
blood through the vessels
when measuring the blood
pressure.
Arteriosclerosis
► Arteriosclerosis:
Artery walls harden;
caused by a diet high
in fat and cholesterol.
► Causes:





Smoking
Diabetes
High Blood Pressure
High Cholesterol
Overweight
Diseases and Disorders of the
Circulatory System
► Stroke:
Happens when a cluster of blood
cells blocks blood vessels in the brain.
► Stroke Stroke is a “Brain Attack”
Diseases and Disorders of the
Circulatory System
► Prevention:





Don’t Smoke
Drink in moderation (21)
Get cholesterol checked
Exercise 30 minutes daily
Consume a low fat diet
► Treatment:
 Medication
 Rehabilitation
Diseases of the Circulatory System
► Leukemia:
Abnormal
white blood cells
 In time they may
crowd out normal
white blood cells,
red blood cells, and
platelets.
Diseases and Disorders of the
Circulatory System
► Hemophilia:
Blood
does not clot properly
► Prevention:
 No prevention, you are
born a hemophiliac
► Treatment:
Transfusions of blood
clotting factors.
