Elementary anatomy and physiology : for colleges, academies, and other schools . elementaryanato00hitc Year: 1869 AND PHYSIOLOGY. 247 are of a conical shape, the apex pointing upwards, the base resting on the Diaphragm, of a pinkish gray color, frequently clotted with black spots, and divided by a deep fissure into two lobes. The right lung is shorter in its Ions; diameter than the left, on account of the liver which raises the right side of the diaphragm higher than the left. The right lung is subdivided again, so that it is really made up of three lobes instead of two. It has also a larger capacity than the left, since the position of the heart, considerably upon the left side of the median line of the body, occupies a portion of the left thorax. Each of the lung3 ordinarily contains a pint of blood. 437. Lobules of tlie Lungs,—A closer examination of the lungs shows them to be made up of small bodies called Lung- lets. These are from th to j^th. of an inch in diameter, and of a conical or pyramidal shape. They are much more clearly denned in small children than in adults.
