HEART, ANATOMY
Model of the superficial anatomy of the heart of an adult human body (anterior view). The heart contains four cavities: two atriums in its upper part, and two ventricles in its lower part. The atriums are covered anteriorly by the auricles (in beige), which increase their blood capacity. The ventricles (in light orange) have superficial grooves (the sulci, in amber yellow), that contains fat and the coronary circulation, feeding the heart muscle. At the boundary between the right atrium and ventricle, the coronary sulcus receives the right coronary artery (in red). In the anterior interventricular sulcus, which marks the boundary between both ventricles, lie the great cardiac vein (in royal blue) and the anterior interventricular branch of left coronary artery (in red). The superior vena cava (in royal blue, in the background) brings the deoxygenated blood to the heart (right atrium), which propels it to the lungs via the pulmonary trunk, dividing in right and left pulmonary arteries (in royal blue, in the foreground). The oxygenated blood is next sent back from the lungs to the heart (left atrium) through the left pulmonary veins (in red). The heart expels then the blood to the whole body via the arch of aorta (in red), which branches into the brachiocephalic trunk, the left common carotid artery and the left subclavian artery. The upper trachea (cartilaginous rings in light blue) and esophagus (in reddish brown) segments are visible behind the heart.
