Study Notes

Heart Anatomy and Components

Superior Vena Cava: Carries deoxygenated blood from the upper body to the right atrium.
Right Ventricle: Pumps deoxygenated blood to the lungs via the pulmonary arteries for oxygenation.
Left Atrium: Receives oxygen-rich blood from the lungs through the pulmonary veins.
Atrioventricular/Tricuspid Valve: Located between the right atrium and right ventricle; prevents backflow of blood during ventricular contraction.
Atrioventricular/Mitral Valve: Situated between the left atrium and left ventricle; ensures blood flows in one direction into the ventricle.
Septum: A muscular wall dividing the right and left 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.
Semi-lunar Valves: Located at the exits of the ventricles; prevent backflow of blood into the heart chambers after contraction.
Left Pulmonary Veins: Carry oxygenated blood from the left lung to the left atrium.
Right Pulmonary Veins: Transport oxygenated blood from the right lung to the left atrium.
Left Pulmonary Arteries: Carry deoxygenated blood from the right ventricle to the left lung.
Right Pulmonary Arteries: Transport deoxygenated blood from the right ventricle to the right lung.
Left Ventricle: Pumps oxygenated blood to the body through the aorta; has thick muscular walls for strong contractions.
Aorta: The largest artery in the body; carries oxygen-rich blood from the left ventricle to the systemic circulation.
Inferior Vena Cava: Returns deoxygenated blood from the lower body to the right atrium.

Description
