HlTH ch. 8

circulatory system

arteriol arteriole
phlebo vein
pulmono lung
septo septum; partition
-ole small
artery carry oxygen rich blood to body tissues
vain carry oxygen poor blood back to the heart
capillaries microscopic blood vessels that receive blood from arterioles
venules join capillaries and veins
systemic circulation general circulation, carries oxygenated blood from the heart to the tissues of the body and returns the blood with much of its oxygen exchanged for carbon dioxide back to the heart
pulmonary circulation circuit that blood makes from the heart to the lungs for the purpose of ridding the body of carbon dioxide and piking up oxygen
mediastinum an area in the chest cavity between the lungs
coronary encircling in the manner of a crown; arteries that supply blood to the heart
myocardium middle layer of the heart
visceral pericardium aka epicardium, lies on the surface of the heart
parietal pericardium outer, tougher layer
pericardial cavity space between the visceral pericardium and parietal pericardium
septum partition that separates right and left chambers of the heart
phlebotomy venipuncture opening of a vein to draw blood for laboratory analysis
inferior vena cava blood from the trunk and legs enter heart
superior vena cava blood from head and arms enters heart
vena cava bring blood to which chamber of the heart? right artrium
the right artrium contracts to force blood through the BLANK into the right ventricle tricuspid valve
the left artrium contracts and forces blood into the left ventricle via the BLANK mitral valve aka bicuspid valve
valvula certain small valves in the body
tricuspid valve located between the right atrium and right ventricle.
bicuspid valve/mitral valve between the left atrium and left ventricle
cuspid refers to the little flaps of tissue that make up the valve
sinoartrial node SA node located at the junction of the right atrium and the superior vena cava. Natural pacemaker of the heart.
Artrioventricular node located near the septal wall between the left and right atria. specialized heart muscle fiber that receive impulses form the sinoatrial node and transmit them to the bundle of his
systole ventricles contract
diastole relaxation of ventricles
holter monitor portable electrocardiograph that a person can wear while conducting normal daily activities
low density proteins LDL associated with an increased risk of cardiovascular disease
high density proteins HDL associated with decreased cardiac risk
lactate dehydrogenase test blood test to assess heart damage
creatine kinase test blood test to assess heart damage
transesophageal echocardiogram (TEE) endoscopic/ultrasound test that provides ultra sonic imaging of the heart form a retrocardiac vantage point
positron emission tomography computerized radiographic technique that uses radioactive substances to examine the myocardial metabolic activity
coronary angiography radiography of the hart and its vessels by injection of radiopaque contrast medium directly into the coronary arteries
digital subtraction angiography, DSA computer enhanced radiographic images of blood vessels filled with contrast
myocarditis cardiomyopathy that results in insufficient oxygen, damaged valves, or high blood pressure
de down, from, or reversing
-stenosis narrowing, stricture
patent ductus arteriosus abnormal opening between the pulmonary artery and aorta
coarctation of the aorta narrowing of a part of the aorta
tetralogy of fallot four congenital heart defects named for the french physician
heart murmurs abnormal heart sounds
heart flutters rapid contractions of either the arita or the ventricles
palpitations subjective sensations of a pounding heart
ventricular fibrillation severe cardiac arrhythmia, ventricular contractions are too rapid and uncoordinated for effective blood circulation
fibrillation cardiac arrhythmia marked by rapid, uncoordinated contractions
heart block impairment in the conduction of the impulse from the SA node to the other parts of the heart
paroxysmal atrial tachycardia (PAT) palpitations and racing heart beat that occur and stop suddenly
atrioventricular block disorder of impulse transmission between the atria and ventricles
ischemia insufficient blood flow to an area
myocardial infarction (MI) necrosis of a portion of cardiac muscle caused obstruction or blood clot in pulmonary artery. Areas of myocardium die from lack of oxygen
infarct localized area of damaged tissue resulting from anoxia
congestive heart failure (CHF) AKA congestive heart disease. abnormal condition that reflects impaired cardiac function
mitral valve prolapse weakening of one or both mitral cusps when the heart contracts
effusion escape of fluid into a part, such as a cavity
cardiac tamponade compression of the heart
shock life threatening, inadequate blood flow to the body's tissues
athero yellowish, fatty plaque
aneurysm localized dilation or ballooning out of the wall of a blood vessel
aortic regurgitation aka aortic insufficiency, blood flows back into the left ventricle during diastole because the aortic valve does not close completely
arteriosclerosis thickening and loss of elasticity of walls of arteries
sclerosis abnormal hardening of tissue
atherosclerosis a form of arteriosclerosis, characterized by formation of fatty deposits on the walls of the arteries
coronary artery disease CAD condition of the coronary arteries that causes a reduced flow of oxygen and nutrients to the myocardium
coronary occlusion obstruction or blockage of a coronary artery
peripheral vascular disease blockage or narrowing of arteries
phlebostasis spontaneous slowing down of blood flow in a vein
tourniquet device applied around an extremity to control circulation and prevent flow of blood to or from the extremities
cardiac pacemaker small battery powered device that is used to increase the heart rate by electrically stimulating the heart muscle
cardio version uses electric shock to restore the normal rhythm of the heart with a device that delivers a direct current shock
cardioplegia solutions used to stop the hearts action so that surgery may be performed
coronary artery bypass open heart surgery; prosthesis or section of a blood vessel is grafted onto one of the coronary arteries
coronary artery bypass graft vessel from another part of the patients body used as an alternate route for blood to circumvent the obstructed coronary artery. CABG (cabbage)
bypass aka shunt
percutaneous coronary intervention (PCI) management of any coronary artery occlusions by andy of the catheter based techniques
percutaneous transluminal coronary angioplasty (PTCA) catheter equipped with an inflatable balloon tip is inserted into a partially occluded coronary artery
intracoronary stent sometimes inserted during PTCA to treat abrupt or threaten closure of a coronary artery
stents sometimes containing drugs to discourage blood clots, expandable mesh like structures that are placed over the angioplarsty site to keep the vessel open
atherectomy specially designed catheter for cutting away plaque from the lining of an artery
endarterectomy surgical excision of arteriosclerotic plaque form inner wall of an obstructed artery
intravascular thrombolysis use of a catheter to deliver a thrombolytic agent to dissolve a blood clot
sclerotherapy direct injection of a sclerosing agent, used for varicose vains
beta blockers drugs given after myocardial infarction to allow heart to work less
calcium channel blockers drugs that help diminish muscle spasms
digoxin well-known cardiac drug, obtained from leaves of digitalis lanata
diuretics meds that are used in the treatment of hypertension, reduce blood volume through excretion of water by the kidneys
heparin antithrombin, prevents intravascular clotting.
nitroglycerin coronary vasodilator
lymphadeno lymph node
lymphangio lymph vessel
lymphogenous originating in the lymphatics; producing lymph or produced from lymph
cisterna chyli structures that are formed by the merging of many lymph vessels and their trunks
spleen, tonsils, and thymus contain lymphatic tissue and are specialized lymphatic organs
tonsils small masses of lymphatic tissue
lingual pertaining to the tongue
lymphogram picture produced in lymphography
lymphedema swelling of the subcutaneous tissue of an extremity as a result of obstruction
adeno gland
splenorrhaphy suture of the spleen
