When the ventricles contract, the bicuspid valve prevents blood from flowing from the ________.
right ventricle to right atrium
left ventricle to left atrium
left atrium to the right atrium
right atrium to the left atrium
Which of the following represents the correct path for the transmission of an impulse during initiation of heart beat?
AV node, Bundle of His, SA node, Purkinje fibers, bundle branches
SA node, AV node, Bundle of His, bundle branches, Purkinje fibers
SA node, Bundle of His, AV node, Purkinje fibers, bundle branches
SA node, Bundle of His, bundle branches, Purkinje fibers, AV node
What area of the heart is responsible for the delay of conduction between the atrium and ventricles?
Right bundle branch
AV node
Bundle of his
Bachmann bundle
What is the important of the delay of impulse conduction between the atrium and ventricles?
To allow the atria to relax, all blood from atria pumped into ventricles, hence atria will empty completely.
To allow the ventricles to contract, pump all blood from atria into ventricles, hence atria will empty completely.
To allow atria to contract, all blood from atria pumped into ventricles, hence atria will empty completely.
Which one is NOT correct about Sinoatrial node?
As pacemaker
Initiate the heartbeat
Generate impulse and spread it to wall of both atrium
Delay impulse from spreading to wall of atria & ventricles simultaneously.
Which one is NOT correct about Atrioventricular node?
Spread impulse to Bundle of His, branches of Bundle of His to the apex of heart and to Purkinje fibers.
Delay the impulse from SA node for about 0.1 second
Generate impulse and spread it to wall of both atrium
Allow the ventricles to contract
