The document discusses the cardiovascular system and high cholesterol. It describes the main parts of the cardiovascular system including capillaries, veins, the heart, and blood vessels. It then discusses several conditions related to high cholesterol, including coronary heart disease, arteriosclerosis, and atherosclerosis. Diagnostic procedures for detecting high cholesterol like serum lipoprotein levels are mentioned. The document concludes by outlining some surgical procedures used to treat conditions caused by high cholesterol, such as endarterectomy and intracoronary artery stents, as well as medications and lifestyle changes that can help treat and prevent coronary artery disease.

1. THE
CARDIOVASCULAR
SYSTEM & HIGH
CHOLESTEROL
BY VANESSA ROSS MOSIER
BIO 120

2. PARTS OF THE CV SYSTEM:
• Capillaries
• Exchange site between
blood and tissues.
• Veins
• (phleb-o)
• Carries blood towards the
heart.
• Heart
• (cardi-o)
• Pumps blood through blood
vessels.
• Blood Vessels
• (hemangi-o)
• Carries blood away from the
heart.

3. CORONARY HEART
DISEASE
Insufficient blood supply
to the heart muscle due
to an obstruction of one
or more coronary
arteries.
• All types of CV
disease have been the
number one killer of
Americans since the
19th century. This
disease kills more
people annually than the
next 6 causes of death
combined.

4. ARTERIOSCLEROSIS
Thickening,
hardening, and
loss of elasticity of
the walls of the
arteries. Most often
due to
artherosclerosis.

5. ATHEROSCLEROSIS
• The most
common form of
arteriosclerosis.
Caused by the
formation of
yellowish plaques
of cholesterol of
the inner walls of
arteries.

6. DIAGNOSTIC
PROCEDURE
Serum lipoprotein
level: Blood test
to measure the
amount of
cholesterol and
triglycerides in
the blood. An
indicator of
atherosclerosis
risk.

7. SURGICAL
PROCEDURES
Endarterectomy:
Removal of the
diseased or
damaged inner
lining of an artery.
Usually
performed to
remove
atherosclerotic
plaques.

8. SURGICAL
PROCEDURES CON’T
Intracoronary
Artery Stent:
Placing of a stent
within a coronary
artery to treat
coronary
ischemia due to
atherosclerosis.

9. WAYS TO TREAT AND
PREVENT CAD
Medications: And of course,
Antilipidemic:
Reduces amount of
cholesterol and
lipids in the
bloodstream.
Names:
Atorvastatin, lipitor,
simvastatin, Zocor
