Function of System
• The cardiovascular system is responsible for
transporting oxygen, nutrients, hormones,
and cellular waste products throughout the
body. This system also controls blood
pressure.

Arteries
Veins
Superior Vena Cava
Heart
Blood
Capillaries
Arterioles
Venules
Aorta
Atrium
Ventricle
Function of Structures
• Aorta: Pumps blood out of the left ventricle
after it is oxygenated into arteries that travel
throughout the body.
• Arteries: Takes oxygenated blood to different
parts of the body.
• Arterioles: Small tubes that extend off of the
arteries that carry blood to the tissues.
• Atrium: Upper cavity of the heart that receives
blood from the vena cava's and the pulmonary
valve and pumps it to the ventricles.
Function of Structures
• Blood: Responsible for transporting oxygen, carbon
dioxide, wastes, and nutrients throughout the body.
• Capillaries: Small vessels that connect veins and
arteries.
• Heart: Main structure of the cardiovascular system.
Receives blood from veins and pumps it to the lungs
to be oxygenated, then gets it back from the lungs
and pumps it to the body.
• Superior Vena Cava: Takes blood into the heart from
the upper half of the body.
Function of Structures
• Vein: To pump deoxygenated blood back to
the heart to be oxygenated.
• Ventricle: Lower chambers of the heart that
pump blood to the lungs and then to the
body.
• Venules: Allow deoxygenated blood to return
from the capillary beds to the veins.
Diabetes Effect on System
• Blood vessels can become damaged.
– Blood can’t flow correctly to all parts of body.
• Can cause swelling and discolored limbs
• Raises the risk for hypertension and atherosclerosis.
Sickle Cell Anemia’s Effect on System
• Sickled Cells are misshapen, which means
they can’t carry oxygen correctly and block
blood vessels.
– This affects oxygen delivery to limbs and your
heart rate, as it has to work harder to pump
more oxygenated blood.
Heart Disease’s Effect on System
• Heart is worn down because of over use.
– High/Low blood pressure
– Heart failure
– Heart may not work properly and can’t
oxygenate blood correctly.
