Anatomy of the Heart

Serous membrane that surrounds the heart

• serous fluid

  
  

• epicardium

  
  

• pericardium

• myocardium

Layer of the heart that is made of cardiac muscle

• endocardium

• epicardium

Vessel that brings blood from the lungs to the left atrium

• pulmonary arteries

  
  

• aorta

  
  

• pulmonary veins

  
  

• vena cavae

  
  

Separates the heart into right and left sides

• AV valve

  
  

• semilunar valve

• left atrium

  
  

white cords that anchor cusps to the wall of the ventricles

• bicuspid valves

• chordae tendinae

  
  

Carries blood from the right ventricle to the lungs

Known as the superior "receiving chambers"
