Veins that return oxygenated blood from the lungs to the left atrium of the heart. Abnormalities can be involved in atrial fibrillation.

The wall separating the left and right ventricles. An important structure as ventricular septal defects are a common congenital heart disease.

This large vein carries deoxygenated blood from the lower half of the body to the right atrium. It can be affected by abdominal pressure changes.

Situated at the lower part of the right atrium near the tricuspid valve. It relays electrical impulses from atria to ventricles.

Located between the right atrium and right ventricle. It prevents backflow of blood into the right atrium during ventricular contraction.

String-like structures that connect the tricuspid and mitral valves to the papillary muscles of the heart. They prevent prolapse of the valves during ventricular contraction.

Found at the junction between the left atrium and left ventricle. It ensures one-way flow of blood into the left ventricle.

A large vein that brings deoxygenated blood from the upper half of the body to the right atrium. Can be involved in venous congestion.

Vessels originating at the base of the aorta supplying the heart muscle with oxygenated blood. Blockage of these arteries can lead to myocardial infarction.

The outermost layer of the heart wall. It serves as a protective layer and contains coronary arteries and veins.

Situated between the left ventricle and the aorta, it maintains unidirectional blood flow from the heart into the aorta.

Located in the right atrium, near the entrance of the superior vena cava. It is the natural pacemaker of the heart.

A collection of heart muscle cells specialized for electrical conduction located at the superior part of the interventricular septum. It transmits impulses from the AV node to the ventricles.

Located between the right ventricle and pulmonary artery. It prevents blood from flowing back into the right ventricle.
