Chambers of the heart:The heart id divided into 4 chambers; 2 thin-walled atria, Which receive venous blood, and two larger, thick-walled ventricles, which pump blood into the arterial system.

Aortic valve:Blood is pumped through here from the left ventricle into the aorta.

Superior vena cava (SVC):Drains blood from the head, neck and upper body into the right atrium.

Pulmonary veins:One of four veins draining blood from lungs into left atrium.

Pulmonary artery:Carries deoxyenated blood from right ventricle via the pulmonary trunk to the lungs.

Right atrium:Receives deoxygenated blood from the SVC and IVC.

Left atrium:Receives oxygenated blood from the pulmonary veins.

Tricuspid valve:Prevents backflow of blood into right atrium from right ventricle.

Inferior vena cava (IVC):Drains blood from the lower body into the right atrium.

Conus arteriosus:Smooth-walled exit from right ventricle to the pulmonary valve at the root of the pulmonary artery.

Mitral Vave:Prevents backflow of blood into left atrium from left ventricle.

Interventricular septum:Partition between the ventricles; mostly muscular but thin and membranous in its uppermost part.

Chordae tendineae:Anchor valve flaps to papillary muscles in ventricular wall.Apex of heart:Tip of left ventricle.
