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.

Test your knowledge of the human heart by labeling key components such as the Superior Vena Cava, Right Ventricle, and various valves. This quiz helps reinforce anatomical understanding through identification of heart structures. Perfect for biology students and anyone interested in human anatomy.
