chapter 8 Flashcards
autonomic nervous system (ANS)
regulates involuntary actions, such as HR, digestion and peristalsis
leaflet
flat, leaf like structure thats includes the valves of the heart and prevents backflow of blood.
lumen
space within an artery, vein, intestine, or tube.
regurgitation
backflow or ejecting of contents through an opening
sphincter
circular muscle constricts or dilates to regulate passage of substances
vasoconstriction
narrowing of blood vessel that limits blood flow caused by disease, meds, physiological processes
vasodilation
widening of lumen of a blood vessel, relaxing of muscle
viscosity
state of being sticky or gummy
aneurysmo/o
widened blood vessel
angio and vasculo
vessel (blood or lymph)
aorto
aorta
arterio
artery
arteriolo
arteriole
atrio
atrium
athero
fatty plaque
cardio and corono
heart
electro
electricity
embolo
embolus
hemangio
blood vessel
myo
muscle
phlebo and veno
vein
sclero
hardening; sclera (white of eye)
septo
septum
sphygmo
pulse
steno
narrowing, stricture
thrombo
blood clot
valvo and valvulo
valve
vaso
vessel; vas deferens; duct
ventriculo
ventricle (of the heart or brain)
Suffix: cardia
heart condition
Sf: gram
record writing
Sf: graph
instrument for recording
Sf: graphy
the process of recording
Sf: stenosis
narrowing, stricture
Prefixes: brady
slow
Pr: endo
in, within
Pr: extra
outside
Pr: peri
is around
Pr: trans
across
angina
chest pain
dyspnea
difficult breathing
arrhythmias
cardiac irregularities
syncope
loss of consciousness
cardiology
disorders of the cardiovascular system
BP: systole
blood is forced out of he heart
BP: diastole
relaxation phase (ventricles are filling with blood
aneurysm
expanding of a vessel in one location
angia
chest pain, caused by low blood flow to the mycocardium
arrhythmia
irregular heart rhythm.
bradycradia
slow heart beat
fibrillation
rapid, uncoordinated of heart muscles (irregular HR)
heart block
blockage of normal transmission of electric impulses (irregular HR)
tachycardia
fast heart rate (irregular HR)
arteriosclerosis
hardening and narrowing of artery and loss of elasticity
atherosclerosis
hardening of plaque (cholesterol and lipids) lumen (narrow)
carotid artery disease
narrowing carotid artery by plaque. can form thrombus and cause stroke
bruit
sound of blood passing an obstruction (murmur)
cardiomyopathy
disease or weakening of heart muscles
coarctation
narrowing of a vessel (especially aorta)
embolism
blood clot, obstruction of blood vessel, effects blood flow
hyperlipidemia
too much lipid in blood (cholesterol, phospholipids etc
hypertension
elevated blood pressure ^140/90mmHg
hypotension
low blood pressure (under 90/60mmHg)
infarction
obstruction of the blood supply to an organ or area of tissue
ischemia
local, temporary deficiency of blood supply to an organ or tissue (obstruction)
mitral valve prolapse (MVP)
backflow of blood
palpitation
sensation of irregular heartbeat
phlebitis
inflammation of a deep or superficial vein (arms or legs)
syncope (fainting)
partial or complete loss of consciousness (reduced blood supply to the brain)
thrombosis
blood clot in a vessel and blocks at the site of formation
deep vein thrombosis (DVT)
blood clot forms in deep vein (legs and thighs)
defibrillation
electrical shock for life-threatening emergency
cardioversion
“heart turning” defibrillation
sclerotherapy
injecting chem irritant into a vein to produce inflammation
thrombolysis
destruction of blood clot using anticlotting agents (clot busters)
