Download Cardiovascular System


Transports nutrients and removes waste
from the body.

Supplies blood and oxygen to the body.
 Heart
 Arteries
 Veins
 Lungs
 Kidneys
Superior Vena Cava
 Right and Left atrium
 Right and left ventricle
 Aorta
 Pulmonary artery
 Arteries

› Supply the oxygen to the heart muscle

Arteries
› Carry blood away from the heart
› Oxygenated
› Carries oxygen all parts of the body

Veins
› Carry blood to the heart
› Deoxygenated
› Carries carbon dioxide and other waste

Lungs
› Where the blood picks up oxygen once you
inhale
› Allows the release of Carbon dioxide once
you exhale

Kidneys
› Filters waste out of the blood
•Coronary Artery Disease (narrowing
the arteries)
•Heart attacks
•Abnormal heart rhythms or
arrhythmias
•Heart failure
•Heart valve disease
•Heart muscle disease
•Pericardial disease
•Vascular Disease (blood vessels)

Atherosclerosis
› Hardening of the arteries that provide vital
oxygen and nutrients to heart

Could eventually cause a part of the
heart muscle (myocardium) die off
› Lack of blood flow.
Steady heart beats about 60-100 times a
minute
 Heart can get out of rhythm called
arrhythmia
 Produce uneven heart beats
 Can change rate

› Cause heart beat to be very slow or very fast

Does not mean heart has stopped
working

Blood is not pumping as well as it should
› Leads to water retention (swelling) and
shortness of breath.

A valve lies at each exit of the four
chamber of the heart
› On way
› Insufficiency

Cardiomyopathies
› Disease in heart muscle
› Also called enlarged heart
› Abnormally thick and enlarge
 Causes weak blood flow
Inflammation of the lining surrounding
the heart
 Rare condition often caused by infection

 Myocardial
infarction
› Myo-muscle
› Cardial-heart
› Infarction-death of tissue due to lack of
blood supply
 Plaque builds up in arteries supplying blood
 Blood clots form around plaque and
totally block the artery
 This causes part of the muscle to be oxygen
deprived and die
 Causes permanent damage to heart muscle
Shortness of breath
 Chest pains

› Discomfort, pressure, heaviness
› Below breast bone





Discomfort in arm, back, jaw, or throat
Sweating, dizziness
Nausea, vomiting
Extreme weakness
Rapid or irregular heart beats

ECG
› EKG- can tell how much damage has
occurred in heart muscle

Blood test
› Look for Cardiac enzymes to indicate muscle
damage

Cardiac catheterization
› Cardiac cath
 Can see direct visual of block artery

Male Sex

Older age

Family history of heart disease

Post- menopausal
Smoking
 High cholesterol

› High LDL “bad cholesterol”

Hypertension
› High blood pressure
Physical inactivity
 Obesity
 Diabetes (uncontrolled)
 Uncontrolled Stress and anger

Do not smoke
 Controlled diet- EAT RIGHT

› Improve cholesterol levels
› Achieve and maintain healthy weight

Regular exercise- BE ACTIVE
› 30-60 minutes most days of the week

Control Hypertension
› Exercise and good diet

Manage Stress
•Cardiovascular disease is the leading cause of
death in both men and women in the US.
•Heart failure is a major health problem in US
affecting 5 million Americans.
•The leading cause of hospitalization in
people over 65
•
About eight out of 1,000 children are
affected by congenital heart disease.
•
Coronary artery disease cause abut
1.2 million heart attacks each year.
About 40 percent will die
