Study Notes
Heart Chambers
- The heart is made up of four chambers
- Two upper chambers, the left atrium and right atrium
- Two lower chambers, the left and right ventricles
Heart Valves
- The heart also has four valves
- Tricuspid valve
- Pulmonary valve
- Mitral valve
- Aortic valve
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
Tricuspid Valve
- Located between the right atrium and the right ventricle
- Has three cusps/leaflets:
- Anterior/anterosuperior
- Septal
- Posterior/inferior
Mitral Valve
- Located between the left atrium and left ventricle
- Has two cusps/leaflets:
- Anterior/aortic
- Posterior/mural
Semilunar Valves
- Prevent backflow from the great vessels to the ventricles
- Pulmonary semilunar valve:
- Between the right ventricle and the pulmonary trunk
- Has three semilunar cusps/leaflets:
- Anterior/non-adjacent
- Left/left adjacent
- Right/right adjacent
- Aortic semilunar valve:
- Between the left ventricle and the opening of the aorta
- Has three semilunar cusps/leaflets:
- Left/left coronary valve
- Right/right coronary valve
- Posterior/non-adjacent
