The two superior chambers are called atria (auricles) and inferior two are called ventricles. Externally, the atria are separated from ventricles by a transverse groove called coronary sulcus or atrioventricular groove. The two ventricles are externally separated from each other by two grooves, the anterior and posterior inter-ventricular sulci. Coronary arteries and coronary veins run through these sulci. Pulmonary trunk arising from right ventricle and aorta from left ventricle are present on anterior surface of heart. The pulmonary trunk bifurcates into right and left pulmonary arteries. Aorta (systemic aorta) is divisible into three regions as ascending aorta, systemic arch /aortic arch and descending aorta. The Ligamentum arteriosum joins pulmonary trunk and aortic arch. It is the remnant of an embryonic duct called ductus arteriosus. The aortic arch gives out three arteries viz. brachiocephalic (innominate) artery, left common carotid and left sub- clavian. The right atrium recieves superior and inferior vena cava along its dorsal surface. Pulmonary veins open into left atrium along the dorsal surface of heart. ---------------------------------------------------------------------------- FOLLOW US ON Facebook :   / abhishekeducare   Instagram :   / abhishekeducare   Twitter :   / abhishekeducare   ---------------------------------------------------------------------------- Thanks For watching............#abhishekeducare #Diagram #Humanheart #Heartdiagram #biologydiagrams #Class12 #12thclassdiagrams
