Which of the following is considered the "pacemaker"?
the Sinoatrial (SA) node
the Atrioventricular (AV) node
the Atrioventricular bundle
the Purkinje fibers
Which of the following is the correct order for the conduction system of the heart?
AV node causes a delay (atria empties & closes valves) and send impulse to AV bundle --> SA node/pacemaker triggers atria to contract and send impulse to AV --> AV bundle sends impulse to bundle branches --> bundle branches send impulses to Purkinje fibers --> Purkinje fibers send impulse through ventricle causes ventricle contraction
SA node/pacemaker triggers atria to contract and send impulse to AV --> AV node causes a delay (atria empties & closes valves) and send impulse to AV bundle --> AV bundle sends impulse to bundle branches --> bundle branches send impulses to Purkinje fibers --> Purkinje fibers send impulse through ventricle causes ventricle contraction
SA node/pacemaker triggers atria to contract and send impulse to AV --> AV node causes a delay (atria empties & closes valves) and send impulse to AV bundle --> bundle branches send impulses to Purkinje fibers --> AV bundle sends impulse to bundle branches --> Purkinje fibers send impulse through ventricle causes ventricle contraction
SA node/pacemaker triggers atria to contract and send impulse to AV --> AV node causes a delay (atria empties & closes valves) and send impulse to AV bundle --> AV bundle sends impulse to bundle branches --> Purkinje fibers send impulse through ventricle causes ventricle contraction --> bundle branches send impulses to Purkinje fibers
Systole is
heart contraction

atrial relaxation
Which is the correct order for the cardiac cycle (events of one full heartbeat)?
Ventricular Systole (AV valves close, blood rushes out of ventricles, and atria filling with blood again) --> Mid-to-late Diastole (atria contract and force blood into ventricles) --> Early Diastole (semilunar valves shut to prevent backflow, AV valves open, ventricle begin to refill)
Mid-to-late Diastole (atria contract and force blood into ventricles) --> Early Diastole (semilunar valves shut to prevent backflow, AV valves open, ventricle begin to refill) --> Ventricular Systole (AV valves close, blood rushes out of ventricles, and atria filling with blood again)
Early Diastole (semilunar valves shut to prevent backflow, AV valves open, ventricle begin to refill) --> Ventricular Systole (AV valves close, blood rushes out of ventricles, and atria filling with blood again) --> Mid-to-late Diastole (atria contract and force blood into ventricles)
Mid-to-late Diastole (atria contract and force blood into ventricles) --> Ventricular Systole (AV valves close, blood rushes out of ventricles, and atria filling with blood again) --> Early Diastole (semilunar valves shut to prevent backflow, AV valves open, ventricle begin to refill)
