Blood flows from the pulmonary veins into the

• Left atrium

• Right atrium

• Left ventricle

• Right ventricle

Label number 2 on the image

• Atrioventricular node

• Bundle of HIS

• Bundle branch

• Sinoatrial node

Label number 4 on the image

• Purkinje fibers

• Bundle branches

• Bundle of HIS

• AV Node

What is the function of the Bundle of HIS?

• Connects the atrial and the ventricles electrically

• Dominant pacemaker of the heart

• Spreads impulses to the atria

• Slows conduction

What is the function of the SA Node?

• Dominant pacemaker of the heart

• Directs electrical impulses between AV & SA nodes

• Slows conduction

• Connects the atria and ventricles electrically

Which of the following splits into two conduction pathways and carries impulese to the interventricular septum at high speeds?

• AV Node

• SA Node

• Bundle Branches

• Purkinje system

• Change in vessel radius

• Viscosity

• Change in vessel length

• Ejection fraction

The term "thrill" is used for blood flow that can be ​ (a)
