The cycle of the heart in its diastole (relaxation) state and its systole (contraction) state. The ventricles can be in a diastolic state, while the atria can be in a systolic state. An auricle is a small conical projection coming out of the atrium, but in some texts it represents the actual atrium. As the heart relaxes, blood enters from the other side and into the atria, then leaves and enters the ventricles. When the heart contracts, blood leaves the ventricles and goes back into the body.

A complex anatomical view of the heart. RA is the right atrium, or auricle, which receives the deoxygenated blood by way of two superior vena cava (SVC) and one inferior vena cava (IVC). The blood passes through the right ventricle (RV) and is pumped up to the lungs via the pulmonary arteries (PA). At the lungs, the blood is reoxygenated and returns via the pulmonary vein (PV) and left atrium/auricle (LA). From there, the blood is passed to the left ventricle (LV) where the blood is pumped up through the systematic arch (SA) to the body. The systematic arch gives off a right innominate artery (INN), where the blood is then passed to the right and left carotid (C) and subclavian (SCL), where the blood goes to the head and arms respectively. It continues dorsally to the dorsal aorta (DA), which is the main artery that distributes blood to the whole body. TR is the windpipe, or trachea, BR is the bronchial tube that carries air to the lungs, and BV is a blood vessel on the wall of the heart.
