Study Notes
Heart Structure and Function
- The heart is a four-chambered organ
- Two upper chambers are the atria (left atrium and right atrium)
- Two lower chambers are the ventricles (left ventricle and right ventricle)
- The heart also has four valves: tricuspid, pulmonary, mitral, and aortic valves
Atrio-Ventricular Valves
- Function: prevent backflow from ventricles to atria
- Tricuspid valve: located between right atrium and right ventricle, has three cusps (anterior/anterosuperior, septal, and posterior/inferior)
- Mitral valve: located between left atrium and left ventricle, has two cusps (anterior/aortic and posterior/mural)
Semilunar Valves
- Function: prevent backflow from great vessels to ventricles
- Pulmonary semilunar valve: located between right ventricle and pulmonary trunk, has three cusps (anterior/non-adjacent, left/left adjacent, and right/right adjacent)
- Aortic semilunar valve: located between left ventricle and aorta, has three cusps (left/left coronary valve, right/right coronary valve, and posterior/non-adjacent)
Left Atrium
- Receives oxygenated blood from the lungs
- Pumps it through the mitral valve to the left ventricle
Left Ventricle
- Pumps oxygen-rich blood to the aorta and the rest of the body
