Non-Communicable
Diseases
Non-Communicable Disease
Diseases that can not be spread from one
person to another.
They are not caused by microorganisms /
pathogens.
They can be treated but not cured
There is no immunity to noncommunicable disease
Causes of Non-Communicable
Disease
Heredity- passed on from parent to child
 cystic fibrosis and down syndrome
 studies have shown that there are
inherited tendencies
Environment
 Where you live or work may cause a
non-communicable disease
Causes of Non-Communicable
Disease
Lifestyle
 Poor health habits- tanning beds,
smoking, drinking, poor diet, lack of
exercise, and emotional stress
Preventing Non-Communicable
Disease
Balanced diet
Regular exercise
Avoid tobacco, alcohol, and other
drugs
Regular check ups can identify early
warnings of disease
Manage stress levels
Circulatory System
Heart: a four chambered muscular pump.
Arteries: supply oxygenated blood to the
entire body (cells, muscles, organs).
Veins: take de-oxygenated blood from the
body and back to the lungs and heart.
Circulatory System
Pulmonary Circuit: carries blood to the
lungs for gas exchange, then returns to
the heart (serviced by the right side of
heart).
Systemic Circuit: supplies blood to every
organ of the body (serviced by the left side
of the heart).
The Heart
The Path of Blood
1. vena cava
2. right atrium
3. right ventricle
4. pulmonary artery (to lungs)
5. gets oxygen from the lungs
6. pulmonary vein (from lungs)
7. left atrium
8. left ventricle
9. aorta (to the rest of the body)
Amazing Heart Facts
Your heart is about the same size as your fist.
An average adult body contains about five
quarts of blood.
All the blood vessels in the body joined end to
end would stretch 62,000 miles or two and a half
times around the earth.
The heart circulates the body's blood supply
about 1,000 times each day.
The heart pumps the equivalent of 5,000 to
6,000 quarts of blood each day.
Heart / Cardiovascular Disease
Disease of the heart and blood vessels
#1 Killer in the USA (men & women)
About 610,000 people die of heart
disease in the US every year–that’s 1 in
every 4 deaths
Every year about 735,000
Americans have a heart attack.
Cardiovascular Disease
Hypertension:
High blood pressure
Caused by excessive pressure
against the arterial walls
No cure
Cardiovascular Disease
Factors of Hypertension:
Stress
Heredity
Sodium intake
Cardiovascular Disease
Treatment of Hypertension:
90% can be controlled
Desirable weight
Reduce sugar, cholesterol, sodium,
and saturated fat intake
Regular exercise
Cardiovascular Disease
Arteriosclerosis- the thickening and
hardening of the arterial walls. The walls
become hard and lose their elasticity.
Atherosclerosis- the build up of plaque
(fatty deposits) on the inner lining of the
arteries.
Atherosclerosis
Heart Attack
Heart Attack- cells in the heart muscle die
resulting from the lack of oxygen and
nutrients due to a blockage in a coronary
artery.
Symptoms: Chest pain or discomfort in the
arms, back, neck, jaw, or upper stomach;
shortness of breath.
Nausea, lightheadedness, or cold sweats.

Heart Attack
Fibrillation- rhythmic disturbance in heart
resulting from muscle fiber that is out of
synchronization.
Stroke- blood supply to the brain is cut off,
resulting in brain cell damage.
Common symptoms of stroke: face
drooping, arm weakness, speech difficulty.
Call 911 even if symptoms disappear.
