Cardiac Conduction

 This triggers contraction in the atria:

• SA node
• AV node
• QT node
• AV Bundles

 This triggers contraction in the ventricle:

• SA node
• AV node
• QT node
• AV Bundles

What is going on in the heart during the P wave?

• SA node triggers contraction in atria
• AV node triggers contraction in ventricle, the main pumpung action
• Delay caused by the SA node
• repolarization of the ventricle 

What is going on in the heart during the QRS wave?

• SA node triggers contraction in atria
• AV node triggers contraction in ventricle, the main pumpung action
• Delay caused by the SA node
• Repolarization of the ventricle 

What is going on in the heart during the T-wave?

• SA node triggers contraction in atria
• AV node triggers contraction in ventricle, the main pumpung action
• Delay caused by the SA node
• Relaxation of the ventricle 

Why are the walls of the left ventricle thicker than that of the right ventricle?

• The left ventricle must force blood into all the capillaries of the lungs 
• the left ventricle doesn't skip leg day
• This is false, the walls of the right ventricle are thicker
• Blood from the left ventricle is pumped throught the entire body 

Blood in arteries is always oxygenated.

• True
• False
• Maybe
• Huh?

Circulation involving the lungs is called...

• Pulmonary Circulation
• Cutaneous Circulation
• Systemic Circulation
• Cardiac Convendency 

These structures aid in spreading contraction signal to ventricles:

• SA Bundles 
• AV Bundles
• Nodal groups
• Heart Murphs

• F
• G
