Quiz: functions of the heart trivia. The heart is one of the major organs in the body; it is tasked with ensuring blood and oxygen is transported throughout the body. Do you know the different part of the heart and their functions? What can happen to them so that they don’t meet their functions? The quiz below is designed for a medical practitioner to see how much they know about the heart and some disorders affecting its different parts.
Pericardium
SA node
Myocardium
Mediastinum
AV valves are closed
Ventricles are relaxed
Ventricles are in systole
Semilunar valves are open
The ventricles are filling with blood
All semilunar valves are open
Both AV valves are closed
Blood is pumped to the lungs and systemic circulation
Decreased ventricular filling (with blood)
Failure of the AV valves to open
Failure of the SA node to fire
Failure of the cardiac impulse to enter the His-Purkinje system
Activation of the beta1 adrenergic receptors
Discharge of sympathetic nerves
Discharge of the vagal nerve
Binding of norepinephrine to its receptor
Vagolytic drug
Beta1 adrenergic agonist
Sympathomimetic
Beta1 adrenergic blocker
Sympathetic nerve firing
Vagal discharge
Activation of the beta1 adrenergic receptors
End diastolic volume (EDV)
A (+) inotrpic drug
A vagolytic drug
A (-) chronotropic drug
A beta1 adrenergic blocker
Activation of beta1 adrenergic receptors
Vagal discharge

"fight or flight"
Norepinephrine
Parasympathetic
