Study Notes
Heart Structure and Function
- The heart is composed of four chambers
- Two upper chambers are the left atrium and right atrium
- Two lower chambers are the left and right ventricles
- The heart also has four valves
- Tricuspid valve
- Pulmonary valve
- Mitral valve
- Aortic valve
Right Atrium
- Receives deoxygenated blood from the body's largest veins (superior vena cava and inferior vena cava)
- Pumps the blood through the tricuspid valve to the right ventricle
Right Ventricle
- Pumps the blood through the pulmonary valve to the lungs for oxygenation
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 (Cardiac output)
Atrioventricular Valves
- Function: Prevents backflow from the ventricles to the atria
- Tricuspid valve:
- Located between the right atrium and right ventricle
- Has three cusps/leaflets (Anterior/anterosuperior, Septal, and Posterior/inferior)
- Mitral valve (Bicuspid valve):
- Located between the left atrium and left ventricle
- Has two cusps/leaflets (Anterior/aortic and Posterior/mural)
Semilunar Valves
- Function: Prevents backflow from the great vessels to the ventricles
- Pulmonary semilunar valve:
- Located between the right ventricle and the pulmonary trunk
- Has three semilunar cusps/leaflets (Anterior/non-adjacent, Left/left adjacent, and Right/right adjacent)
- Aortic semilunar valve:
- Located between the left ventricle and the opening of the aorta
- Has three semilunar cusps/leaflets (Left/left coronary valve, Right/right coronary valve, and Posterior/non-adjacent)
