Non-bell-work (Heart Cycle)

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 

What is the definition of the Cardiac Cycle?

• the contraction of the atria
• the sequence of events that occur during one complete heartbeat
• the contraction and relaxation of the ventricles
• the circulation of blood in the heart

Which valves will be open during ventricular systole?

• Bicuspid valve

• Tricuspid valve

• Semi-lunar valves at base of aorta.

• All of the above

Carries the blood from the ventricle to the body

• Aorta
• Atrium
• Valve
• Septum

A flap of tissue that prevents blood from flowing backward

• Aorta
• Atrium
• Septum
• Valve
