Study Notes
Heart Structures
- The circulatory system includes the heart, blood vessels, and blood.
- Valves between the atria and ventricles, and those between ventricles and blood vessels prevent backward blood flow.
Blood Vessels and Chambers
- Superior Vena Cava: Large vein carrying oxygen-poor blood from the upper body to the right atrium.
- Pulmonary Veins: Carry oxygen-rich blood from the lungs to the left atrium.
- Aorta: Carries oxygen-rich blood from the left ventricle to the body.
- Pulmonary Arteries: Carry oxygen-poor blood to the lungs (either right or left).
- Right Atrium: Receives oxygen-poor blood from the body.
- Left Atrium: Receives oxygen-rich blood from the lungs.
- Right Ventricle: Pumps oxygen-poor blood to the lungs.
- Left Ventricle: Pumps oxygen-rich blood to the body.
- Inferior Vena Cava: Vein carrying oxygen-poor blood from the lower body to the right atrium.
Heart Valves
- Pulmonary Valve: Prevents backflow of blood from the pulmonary artery into the right ventricle.
- Tricuspid Valve: Prevents backflow of blood from the right ventricle into the right atrium.
- Aortic Valve: Prevents backflow of blood from the aorta into the left ventricle.
- Mitral Valve: Prevents backflow of blood from the left ventricle into the left atrium.
Additional Structures
- Septum: Divides the heart into left and right halves.
