Cardiovascular System Quiz(Cardiovascular)

What is the natural pacemaker of the heart called?

• AV node (Atrioventricular node)

• SA node (sinoatrial node)

• Purkinje fibers

• Bundle branches

One complete contraction and relaxation of the heart is called

• heart rate
• blood pressure
• ventricular contraction
• cardiac cycle

cardiopulmonary resuscitation

• emergent life support = artificial respiration + manual chest compression 

• emergent life support = CPR + manual chest compression 

• emergent life support = manual chest compression + electic shock

Electrical impulse

• SA node = AV node = AV bundle = bundle branches = Purkinje fibers = ventricles 

• SA node = AV node = AV bundle =ventricles = bundle branches = Purkinje fibers  

• SA node = AV node = bundle branches= AV bundle = Purkinje fibers = ventricles 

What is the condition of having an abnormally slow resting heartbeat called?

• Tachycardia

• Bradycardia

• Myocarditis

• Pericarditis

what does the right Coronary Artery brings?

PS: any damage to this artery can cause bradycardia 

• The right coronary artery supplies blood to the brain (and the AV node).

• The right coronary artery carries deoxygenated blood to the lungs.
• The right coronary artery brings oxygenated blood the SA node 
  (and the AV node).

• The right coronary artery is responsible for pumping blood to the stomach.

Sphygmomanometers measureS

• body temperature
• arterial heart rate

• arterial blood pressure

What is the highest pressure against the arterial wall known as?

• Diastolic blood pressure

• Myocardial pressure

• Systolic blood pressure

• Pericardial pressure

Relaxation of the heart is called

• diastole
• atrial relaxation
• ventricular contraction
• systole

Diastolic blood pressure is the lowest pressure against

• the lungs wall

• the arteries wall

• the heart wall

• the veins
