Cards

Term
atria
Definition
collecting chambers that receive blood from the rest of the body.
Term
ventricles
Definition
the heart's two lower chambers, which pump blood through the blood vessels.
Term
tricuspid valve
Definition
located between the right atrium and right ventricle
Term
pulmonary valve
Definition
located between right ventricle and pulmonary artery
Term
mitral valve
Definition
between left atrium and left ventricle
Term
aortic valve
Definition
between the left ventricle and the aorta
Term
arteries
Definition
carry blood away from the heart; all arteries transport oxygenated blood, except for pulmonary arteries, which carry deoxygenated blood to the lungs, where the blood picks up oxygen and gives off carbon dioxide.
Term
arterioles
Definition
branches of arteries
Term
capillaries
Definition
have thin walls that permit the exchange of oxygen, ox, nutrients and waste with body cells.
Term
veins
Definition
vessels that carry blood back to the heart from other regions of the body.
Term
venules
Definition
branches of the veins.
Term
sinoatrial node (SA NODE)
Definition
located in the right atrium, serves as a natural pacemaker for the heart.
Term
artheriosclerosis
Definition
thickening and hardening of the arteries, a condition that underlies many cardiovascular health problems and is believed to be the biggest contributor to disease burden globally.
Term
atherosclerosis
Definition
a type of arteriosclerosis and is characterized by deposits of fatty substances, cholesterol, cellular waste products, calcium and fibrin (clothing material in blood) in the inner lining of an artery.
Term
plaque
Definition
buildup of deposits in arteries.
Term
thombus
Definition
blood clot attached to a blood vessel's wall.
Term
embolus
Definition
a blood clot that becomes dislodged from a blood vessel wall and moves through the circulatory system.
Term
collateral circulation
Definition
adaption of the heart to partial damage accomplished by rerouting needed blood through unused or underused blood vessels while the damaged heart muscle heals.
Term
ischemia
Definition
reduced oxygen supply to a body part or organ
Term
angina pectoris
Definition
chest pain, indicates underlying heart disease. This results in reduced oxygen flow to the heart.
Term
fibrillation
Definition
a sporadic, quivering pattern of heart beat that results in extreme inefficiency in moving blood thorough the cardiovascular system.
Term
congestive hart failure
Definition
affects over 5 million Americans and dramatically increases risk of premature death. The heart muscle may be injured by numerous health conditions, including rheumatic fever, pneumonia, heart attack or other cardiovascular problems. In some cases, the damage is due to radiation or chemotherapy treatments for cancer.
Term
what are some treatments for CHF?
Definition
DIURETICS (WATER PILLS) to receive fluid accumulation;
digitalis increase the heart's pumping action
vasodilators drugs that expand blood vessels and decrease resistance, allowing blood to flow more easily and making heart's work easier.
Term
congenital heart disease
Definition
this disease is present at birth. Forms can be slightly minor such as murmurs caused by valve irregulataries that some children outgrow.
Term
rheumatic heart disease
Definition
a heart disease caused by untreated strep throat.
Term
stroke
Definition
also called cerbrovascular accident, occurs when the blood supply to the brain is interrupted.
Term
transient ischemic attack
Definition
brief interruption of the blood supply to the brain that causes only temporary impairment; often an indicator of impending major stroke.
Term
stytolic pressure
Definition
the pressure being applied to the artery walls when the heart contracts, pumping blood to the rest of the body.
Term
diastolic pressure
Definition
the pressure applied to the artery walls during the heart's relaxation phase.
Term
hypertension
Definition
refers to sustained high pressure.
Term
diastolic pressure
Definition
the pressure applied to the artery walls during the heart's relaxation phase.
Term
metabolic syndrome
Definition
a group of metabolic conditions occuring together that increase a person's risk of heart disease, stroke, and diabetes
Term
ECG
Definition
is a record of the heart's electrical activity. Patients undergo a stress test
Term
angiography
Definition
a technique for examining blockages in heart arteries.
Term
PET
Definition
METHOD FOR MEASURING HEART ACTIVITY BY INJECTING A PATIENT WITH A RADIOACTIVE tracer that is scanned electronically to produce a three dimensional image of the heart.
Term
angoplasty
Definition
a technique in which a catheter with a balloon at the tip is inserted to a clogged artery; the balloon is inflated to flatten fatty deposits against artery walls and a stent is typically inserted to keep the artery open.
Term
thrombolysis
Definition
injection of an agent to dissolve clots and restore some blood flow, therby reducing the amount of tissue that dies from ischemia.
