Exploring Medicine Final question and
answers
circulatory system - Answer brings nutrients to and wastes from the cells and tissues in the body
blood is made up of - Answer cells and serum
systole - Answer ventricular contraction/ highest pressure
diastole - Answer ventricular relaxation/ lowest pressure
cardiac output - Answer how much blood the heart puts out in one minute
cardiac output equation - Answer CO=SV+HR
atrial contraction - Answer induced by SA node
AV node - Answer holds to allow for mechanical contraction of the atria completely before contraction
of the ventricle
what follows depolarization - Answer contraction
completion of systole - Answer ventricular emptying
ischemia - Answer decreased blood flow to a portion of the heart as a result of an occlusion of the
coronary artery
acute myocardial infarction - Answer ST elevations
catecholamines - Answer epi and norepi, effect blood pressure
, oncotic pressure - Answer draws fluid into vascular space, inward force
hydrostatic pressure - Answer draws fluid out,
if hydrostatic pressure high - Answer more fluid will be transported into interstitial space/ edema
if hydrostatic pressures low - Answer more fluid will be transported into the intravascular space
if oncotic pressures low - Answer more fluid into interstitial space/ edema
definition of shock - Answer a decrease in circulation of O2 and/or nutrients to tissues to the point that
those tissues malfunction, become damaged, and ultimately, in severe cases, are destroyed
ABC's - Answer airway, breathing, circulation
blood flow to tissues - Answer blood volume, vascular capacitance and resistance
hypovolemic shock - Answer when hydrostatic pressure is reduced
cardiogenic shock - Answer poor perfusion to tissues, heart not functioning well/ decrease in CO
vasogenic shock - Answer decreased perfusion to the core of the body/ abnormal dilation of blood
vessels
mechanical shock - Answer problem with blood flow due to something outside of cardiovascular system
3 stages of shock - Answer 1. compensatory 2. non-compensatory 3. terminal
