Just another reference: The lungs take the shape of the pleural cavities, and are conical structures having an apex which projects above the level of the first rib for about half an inch, and a concave base which is adapted to the cupola of the diaphragm, on which it rests. The outer surface is smooth and convex, except for shallow grooves made by the ribs, and the inner surface has the impressions of the organs against which it lies. The lower border of the outer surface of the lung is thin and reaches down between the diaphragm and the ribs to the level of the lower border of the sixth rib in front; the eighth rib in the mid-axillary line; then passes horizontally inwards, reaching the vertebral column at the level of the tenth rib. The bases of the lungs are in relation with some of the abdominal organs, the diaphragm intervening. Thus, the base of the right lung rests upon the right lobe of the liver, whilst the base of the left lung is in relation with the left lobe of the liver, the fundus of the stomach, and the spleen. http://chestofbooks.com/health/body/massage/Handbook-Of-Anatomy-For-Students-Of-Massage/Lungs.html "
