Document Summary

Concaved inferior surface because lungs sit on top over the convex upper surface of diaphragm. Pointed (superior)apex protruding up from top of lung above the level of first rib. Rounded lateral surface sitting against lateral boundary of lung cavity and imprints of ribs are bared: can be seen by telling the grooves by the rib. Mediastinum surface facing medially (hilum/lung root associated with it) Posterior aspect of lung (sits right back next to vertebral column) is chunky, thick and rounded. Anterior aspect is thin thin so it can come around the fill the space between heart and sternum when breathing. Right: usually larger than left lung, three lobes, fissures incompletely separate each lobe - lung is one entity; fissures are aligned by extensions of visceral pleura covering the lung. Which means that the lower lobe is posterior: fissures can be absent in some lungs should not be used to identify lungs.
