the heart called?
• epicardium
• What is the middle, muscular wall of the heart
called?
• myocardium
• What is the inner layer of the heart called?
• Endocardium
• What interconnects the cardiac muscle cells
and helps to convey the force of contraction?
• Intercalated disks

The right atrium receives blood from the…
Superior vena cava
Inferior vena cava
Coronary sinus
• What is the function of the valves in the
heart?
• To prevent back flow of blood
• What is the function of the chordae tendineae
and papillary muscles?
• To prevent the valve from opening backwards
• Which valve separates the right atrium from
the right ventricle?

• Body through the aorta
• What are the structural differences between
the right and left ventricle?
• The left ventricle has a thicker wall and is
round, while the right ventricle has a thin wall
and is pouch shaped
• What is the blood supply to the heart called?
• Coronary circulation

• Heartbeat
• What are the 3 structures of the conducting
system?
• Sinoatrial node
• Atrioventricular node
