100% CORRECT | 2024 UPDATE!!
Components of coronary circulation - ✔✔✔ Correct Answer
> Right coronary artery, left coronary artery, coronary sinus,
coronary vein, great coronary vein
ventricular action potential - ✔✔✔ Correct Answer > divided
into phases 0,1,2,3,4
Phase 0 of ventricular action potential - ✔✔✔ Correct
Answer > Na+ rushes into the cell, rapid depolarization
Purkinje Fibers - ✔✔✔ Correct Answer > impulse conduction,
at base of the heart, trigger muscle fibers ventricles to contract,
maintain constant cardiac rhythm
,Vital capacity - ✔✔✔ Correct Answer > VC, sum of tidal
volume, inspiratory reserve volume, and expiratory reserve
volume. volume of air that can be forcibly expired after a
maximal inspriation
Total lung capacity - ✔✔✔ Correct Answer > TLC, sum of
tidal volume, IRV, expiratory reserve volume and residual
volume, volume in the lungs after a maximal inspiration
Forced vital capacity - ✔✔✔ Correct Answer > FVC,
maximum volume of air forcibly exhaling form the point of
maximal inhalation
cardiac conduction pathway - ✔✔✔ Correct Answer > SA
node, AV node, bundle of His, right and left bundle branches,
Purkinje fibers
Phase 1 of ventricular action potential - ✔✔✔ Correct
Answer > K+ channels open and K+ is rushing out of the cell,
initial depolarization
, Phase 2 of ventricular action potential - ✔✔✔ Correct
Answer > "plateau", repolarization, concentration of K+
leaving the cell and Ca+ coming into the cell is equal
Phase 3 of ventricular action potential - ✔✔✔ Correct
Answer > Na+/K+ ATPase pump becomes active, this is the
resting phase
Cardiac cycle - ✔✔✔ Correct Answer > one cardiac cycle =
one heart beat = systole + diastole
Flow of coronary circulation - ✔✔✔ Correct Answer > aorta -
RCA/LCA - R/L heart - Cardiac veins, coronary sinus - right
atrium
perciardium - ✔✔✔ Correct Answer > fibrous, partial, cavity,
visceral
myocardium - ✔✔✔ Correct Answer > contains
cardiomyocytes
endothelium - ✔✔✔ Correct Answer > lumen
