Cardiovascular System
Network of organs and vessels through which the blood flows as it carries oxygen and nutrients
atria
the hearts two upper chambers: receive blood
ventricles
two lower chambers of the heart. pump blood through blood vessels
arteries
vessels that carry blood away away from the heart.
Pulmonary Arteries (What do they carry)
De oxygenated blood. to the lungs.
arterioles
Branches of arteries (smaller denomination)
capillaries
(smallest denomination) branches from arterioles / venules. thin walls exchange oxygen carbon dioxide nutrients and waste products among body cells.
veins / venules
transport carbon dioxide / waste products to lungs / kidneys.
sinoatrial node (SA node)
Cluster of electric pulse generating cells that serve as natural pacemaker for heart.
average heart rate beat
70 to 80 times per minute
well conditioned heart rate beat
50 to 60
troubled heart beat
80 to 90 bpm
#1 Cause of death and more than next three deaths combined
Cardiovascular Disease(s)
sudden cardiac arrest
abrupt profound loss of heart function
next three leading causes of death:
cancer, chronic lower respiratory diseases, accidents.
#1 killer in cardiovascular disease category
Coronary Heart Disease
Atherosclerosis
fatty substances (waste products) build up in inner lining of artery.
Hyperlipidemia
Abnormally high blood lipid level
ischemia
limit to oxygen supply
Coronary Heart Disease
Greatest Killer in cardiovascular disease category.
Coronary Thombosis
clot
thrombus
clot
embolus
dislodged clot
stroke
blood supply to brain is interrupted.
ischemic
reduced blood flow
hemorrhagic
rupture of blood
TIA (Transient Ischemic Attacks)
brief interruption to brain blood supply. Temporary impairment.
Healthy Blood Pressure
120/80
Nitroglycerin
drug used to relax (dilate) veins
Congestive Heart Failure
damaged / overworking heart muscle is unable to keep blood flow circulating normally
HDL (High Density Lipids)
at least 60 mg/dl and above (good lipid)
LDL (Low Density Lipids)
(bad lipid) less than 100 mg / dl
Angioplasty
involves threading a thin catheter through blocked artieries.
Stance on Aspirin
NOT recommended to stop heart failure.
Diabetes is?
Fastest growing chronic disease in america
Diabetes Mellitus
persistently high level of blood glucose and an unusually high glucose in urine.
Type 2 percentage of cases
(90-95%) Type I more serious.
peripheral artery disease
atherosclerosis in lower extremities (feet etc)
angina pectoris
condition with chest pain caused by reduced oxygen flow to heart
Rheumatic heart disease
untreated streptococcal infection in throat.
metabolic syndrome
group of metabolic syndromes in conjunction to increase risk of heart disease, stroke, and diabeetus
Triglycerides
most common lipid in body. excess calories are converted into this and stored as body fat.
Techniques to detect issues:
electrocardiogram (ECG), aniography, Positron Emission Tomography (PET SCAN(
electrocardiogram
record of electrical activity of heart.
aniography
technique for examining blockages in heart arteries
PET SCAN
measure heart activity by injecting patient w/ radioactive tracer that is scanned electronically to detect issues
angioplasty
catherer surgery
