What is pulmonary circulation? - (answer)Blood from RV to lungs and back to LA.
What is systemic circulation? - (answer)Blood from LV to body and back to RA.
What is coronary circulation? - (answer)Blood flow to and from the heart tissue.
What is the pacemaker of the heart? - (answer)SA node.
What does the AV node do? - (answer)Delays impulse so atria contract first.
Path of cardiac conduction? - (answer)SA node --> AV node --> Bundle of His --> Purkinje fibers.
,NSG 532 Exam 2 – Advanced Nursing Practice Study Guide & Practice Questions
What is the function of Purkinje fibers? - (answer)Rapidly conduct impulses to ventricles.
What does the P wave represent? - (answer)Atrial depolarization.
What does the PR interval indicate? - (answer)AV node delay.
