During the cardiac cycle (heart beat), which chambers contract first?
atria
ventricles
blood vessels
none of these are correct
The ______________ node is the junction between atria and ventricles. This receives the electrical signal from the SA node.
Atrioventricular (AV)
sinoatrial (SA)
bundle branches
purkinje fibers
bundle of His
The ______________ node is the pacemaker of the heart that is located at the top of the right atrium and establishes the heart rate.
Atrioventricular (AV)
sinoatrial (SA)
bundle branches
purkinje fibers

Which of the following are characteristics of arteries? (pick 3)
carry blood away from the heart
carry blood toward the heart
High pressure
Thicker walls and more smooth muscle
Contain valves and surrounded by body muscle
Which of the following are characteristics of veins? (pick 3)
carry blood away from the heart
carry blood toward the heart
lower pressure and thinner walls with less smooth muscle
Thicker walls and more smooth muscle
Contain valves and surrounded by body muscle
True or False: The following is the correct sequence of events for the electrical conduction through the heart:
1. SA node begins the action potential
2. Stimulus spreads to the AV node
3. Impulse is delayed at AV node
4. Impulse then travels through ventricular conducting cells
5. Then distributed by Purkinje fibers
True
False
