Theribs are numbered. Fig. 37 that the lungs extend up above the clavicles and overlapthe liver and the heart—facts of considerable importance in thephysical examination of these organs, as will be later seen. Itis also to be noticed how small a portion of the stomach isdirectly accessible to physical examination, the larger part of itlying behind the ribs and covered by the liver. The normal pan-creas and kidneys are practically inaccessible to physical examina-tion.
