<P> The human heart is situated in the middle mediastinum , at the level of thoracic vertebrae T5 - T8 . A double - membraned sac called the pericardium surrounds the heart and attaches to the mediastinum . The back surface of the heart lies near the vertebral column , and the front surface sits behind the sternum and rib cartilages . The upper part of the heart is the attachment point for several large blood vessels -- the venae cavae , aorta and pulmonary trunk . The upper part of the heart is located at the level of the third costal cartilage . The lower tip of the heart , the apex , lies to the left of the sternum ( 8 to 9 cm from the midsternal line ) between the junction of the fourth and fifth ribs near their articulation with the costal cartilages . </P>
