Med Term Review Pt. 2 Flashcards
(222 cards)
pulmonary circulation
goes from right side of heart to lungs and back; exchanges CO2 for O2 in lungs
systemic circulation
circulation from left side of heart to body and back; exchanges O2 for CO2 in body
diastole
ventricular relaxation; bottom number on BP monitor
systole
ventricular contraction; top number on BP monitor;
which number is more concerning on a BP monitor when it is really high?
diastole because that is when your heart is relaxing and filling up with blood
angina
severe chest pain due to ischemia to the myocardium; usually due to exertion; pain goes away once they stop what they were doing; pain can radiate into left arm and if bad enough into the back; bc of a almost or fully blocked artery (atherosclerosis –> arteriostenosis)
CHF
coronary heart failure; end stage heart disease; ventricles are so damaged they can’t pump blood to every part of the body; leads to back up of blood in the heart; the heart starts to enlarge causes the lining/walls to thin out; then scarring and adhesions occur; high BP; takes years
MI
myocardial infarction; heart attack; blockage of coronary artery which results in death of the myocardium; 10 min max to revive and do angioplasty
Ballon Angioplasty
PCTA, used in MI, uses a balloon to open up clogged artery; minimally invasive;
CABG
coronary artery bypass graft; bypassing a blocked artery w/ another artery taken from somewhere else in the body like the leg
hypertension
high BP
angiogram
used to locate blockage of artery; uses dye with catheter; fluoroscopy; live x-ray
flouroscopy
live x-ray; not showing the heart in motion; just the outline of heart; guideline
atherosclerosis
hardening of artery due to plaque
what can atherosclerosis cause?
arteriostenosis
arteriostenosis
narrowing of the artery
HDL
good cholesterol; should almost always be lower than LDL; under 200; whole grains; leafy greens; fruits
LDL
bad cholesterol; red meat, fried foods, non whole grains
arrhythmia
electrical impulse through the heart is messed up; abnormal; irregular heartbeat
pacemaker
tx for arrhythmia; internal defibrillator, regulates HR
function of lymphatic system
blood carries life sustaining O2 + nutrients to tissues
WBC
leukocyte; white blood cell; fight infections and strengthen immune system
RBC
erythrocyte; red blood cells; carry O2 to tissues and CO2 to lungs
thrombocyte
platelets; helps with clotting and coagulation
