Not caused by pathogens
Cannot be transmitted to other people
Risk factors:
◦ Genetics
◦ Life-style
◦ Environmental factors


Determined by genes
Congenital disease is present at birth
◦ Others don’t show up until later in life

Familial Disease Tendency
◦ Disease runs in family

Recessive gene disorders
◦ Need recessive gene from
both parents
◦ Can be a carrier
◦ Cystic fibrosis & sickle cell
anemia

Down syndrome
◦ Born with extra chromosome

Sex-linked disorders
◦ Linked to x chromosome
(female)
◦ Can be recessive in females
◦ Color blindness, hemophilia, &
muscular dystrophy

Disease of Cardiovascular system
CV system is…
◦ Heart
◦ Blood Vessels
 Arteries
 Vein
 Capillaries
◦ Blood


Hypertension
Arteriosclerosis
Atherosclerosis
Heart Attack
Stroke
Arrhythmias
Heart Valve Disorder
Varicose Veins



High Blood Pressure
Normal=120/80
Over 120/80= At risk
High=150/90
Thickening of blood vessel walls
Narrows passageways for blood



Hardening of the
arteries
Narrows blood
vessels & blocks
blood flow
Atherosclerosis
◦ Fat deposits in blood
vessels


Caused by lack of oxygen delivery to cells
Coronary heart disease
◦ Blockage of coronary arteries
◦ Caused by fat deposits and/or blood clots
◦ Causes heart attack

Cardiac Arrest
◦ Entire heart stops





Disrupts blood flow to brain
No oxygen to brain
Brain cells die
Caused by fatty deposits, blood clots, or
burst arteries
Aneurysm
◦ Weak spot in blood vessel that can burst


the brain




4 valves in heart
2 between atria & ventricle
2 between heart & arteries
Bypass Surgery
Arrhythmias
 Abnormal
heart beat
 Pacemaker
 Defibrillator
Varicose Veins
•Large blue
veins
•One-way
valves don’t
work

Electrocardiogram (ECG/ EKG)
◦ Graphs electrical impulses and heart beats

Stress Test
◦ ECG during exercise

Chest X-Ray
◦ Picture of heart




Don’t smoke
Exercise regularly
Manage stress
Manage diet
◦
◦
◦
◦
Avoid saturated fat & cholesterol
Replace red meat with chicken and fish
Eat more fruits & veggies
Avoid sweets, oils, & fats

Early detection!!!!!!!!
Screening
◦ Self-test
◦ Pap-test
 Cervical examination
◦ Colonoscopy
 Looks inside colon
◦ Biopsy
 Removal of cell/ tissue for examination

Chemotherapy
◦ Drugs that kill cancer cell
◦ Often taken in combination
◦ Pill or injection form

Radiation Therapy

Surgery
◦ Radiation can stop growth/ division
of cancer cells
◦ Removal of tumor or cancer cells
