Aorta
largest artery in the body
Aorta
Aort/o
Aortic semi lunar valve
left ventricle flows into aorta
Atrioventricular (AV) node
receives electrical impulse from SA node and sends it to the Bundle of His
Left atrium
where pulmonary veins flow
right atrium
where superior and inferior vena cava flow
Bicuspsid/ mitral valve
left atrium into left ventricle, MOST common valve to fail
Bundle of his
helps form conduction myofibres that extend to ventricle walls and stimulate them to contract. (connects AV node to rest of conduction system)
Coronary Arteries
Blood vessels that carry oxygen-rich blood to the heart muscle
inferior vena cava
VEIN that carries DOB from the body to the heart. (on the bottom of heart)
Pericardium
Double-layered membrane surrounding the heart
Pulmonary Artery
Artery that carries DOB from heart to the lungs
pulmonary semi lunar valve
right ventricle into pulmonary artery
pulmonary vein
One of two pairs of vessels carrying oxygenated blood from the lungs to the heart
septum
Partition or wall dividing the chambers of the heart
Sinoatrial/SA node
Specialized nervous tissue in the right atrium that begins the heartbeat, pacemaker
Superior Vena Cava
Vein that carries DOB from body to heart, located on the top of the heart.
Tricuspid Valve
Located between the upper and lower right heart chambers (atrium and ventricle)
Left ventricle
below left atrium
right ventricle
below right atrium
Sphygmomanometer
Tool that measures blood pressure
Stethoscope
amplify internal sounds of heart, lungs, body
Diastole
bicuspid and tricuspid opening, relaxation phase of heartbeat
systole
Semi lunar valves opening; contraction phase of heartbeat
pulse
Beat of the heart as felt through the wall of the arteries
vena cava
Largest vein in the body
ventricle
Lower chamber of the heart
Angina
chest pain caused by reduced blood flow to the heart. relieved with nitroglycerin, can be a symptom of coronary artery disease
Arrhythmia
Abnormal rhythms of the heart.
cardiomyopathy
disease of the heart muscle
coarctation of the aorta
Localized narrowing (stenosis) of Aorta, reduces supply of blood to the lower part of the body.
Congestive Heart Failure, CHF
Heart cant pump required amount of blood, results in pulmonary edema(too much fluid in lungs). Fatal if left untreated.
Primary cause in us is HPB and Coronary artery disease
coronary Artery disease
Plaque hardening in arteries
causes atherosclerosis (fat in arteries) and Acute coronary syndrome (reduced blood flow to heart)
Essential hypertension
high blood pressure with no identifiable cause
Fibrillation
quivering, prevents effective movement of blood (Atrial and Ventricular)
Flutter
Regular but rapid rhythm of contractions
Hypertensive heart disease
high BP from arterial stenosis
Infarction
Heart Attack due to blockage
Mitral Valve Prolapse
Improper closure of mitral valve
Tetralogy of fallot
Heart doesn’t develop correctly, causes hole in ventricular system (septal defects), pulmonary stenosis, ventricular hypotrophy (thicker myocardial mass), and shift of aorta
Patent ductus arteriosus
pulsus arteriosus fails to close after birth, so blood from aorta flows into the pulmonary artery
Myocardial infarction
heart attack, decreased or complete cessation of blood flow to a portion of the myocardium
angi/o
vessel
ather/o
fatty substance
atri/o
atrium
-blast
immature cell
cardi/o

myel/o
bone marrow
phleb/o
vein
-poiesis
formation
pulmon/o
lung
sphygm/o
pulse
-stasis
to stop, control, place
pulmonary circulation
right side of heart to lungs and back
systemic circulation
left side of heart and aorta to body and back
cardiac circulation
coronary arteries supply the heart with oxygen and nutrients
thromb/o
clot
vas/o
vesssel
ven/o
vein
axill/o
armpid
ox/o

mitral valve prolapse
improper closure of mitral valve
aneurysm
local widening of artery
petechiae
small, pinpoint hemorrhagews
digoxin
drug to strengthen heartbeat
CK, LD, and AST are
serum enzymes
ECHO
high frequency sound waves transmitted into chest
phlebotomy
incision of vein
DVT
blood clot in large lower limb vessel
endocardium
inner lining of heart
endothelium
inner lining of blood vessels
steth/p
chest
murmur
Abnormal swishing sound caused by improper closure of the heart valves.
