Label the Heart Diagram

Study Notes

Heart Anatomy Terms

Superior Vena Cava
- Major vein that carries deoxygenated blood from the upper body to the right atrium.
Right Ventricle
- Chamber of the heart responsible for pumping deoxygenated blood to the lungs via the pulmonary arteries.
Left Atrium
- Chamber that receives oxygenated blood from the pulmonary veins and transfers it to the left ventricle.
Atrioventricular/Tricuspid Valve
- Valve located between the right atrium and right ventricle, prevents backflow of blood during ventricular contraction.
Atrioventricular/Mitral Valve
- Valve situated between the left atrium and left ventricle, ensures one-way blood flow from atrium to ventricle.
Septum
- Muscular wall that separates the left and right sides of the heart, prevents mixing of oxygenated and deoxygenated blood.
Right Atrium
- Receives deoxygenated blood from the body via the superior and inferior vena cavae and directs it to the right ventricle.
Semi-lunar Valves
- Valves located at the exit of the ventricles (pulmonary and aortic), prevent backflow of blood into the ventricles after contraction.
Left Pulmonary Veins
- Four veins that carry oxygenated blood from the lungs to the left atrium.
Right Pulmonary Veins
- Four veins that transport oxygenated blood from the right lung to the left atrium.
Left Pulmonary Arteries
- Two arteries that carry deoxygenated blood from the right ventricle to the left lung for oxygenation.
Right Pulmonary Arteries
- Two arteries that lead deoxygenated blood from the right ventricle to the right lung for oxygenation.
Left Ventricle
- Chamber of the heart that pumps oxygenated blood into the aorta to supply the body; possesses thick muscular walls for strong contractions.
Aorta
- The largest artery in the body, distributes oxygenated blood from the left ventricle to all parts of the body.
Inferior Vena Cava
- Major vein that carries deoxygenated blood from the lower body to the right atrium.
