Liver.
—The liver is the largest gland in the body, and is situated in the upper and right part of the abdominal cavity, occupying almost the whole of the right hypochondriac, the greater part of the epigastric, and extending almost to the middle of the left hypochondriac region.
In the male it weighs from fifty to sixty ounces, and in the female, from forty to fifty.
It is relatively much larger in the foetus, being about one-eighteenth of the body weight in the foetus, and in the adult, about one-thirty-sixth of the body weight.
Its greatest width is from seven to eight inches, is about twelve inches long, and in its greatest thickness about three inches.
The liver is very soft and is easily lacerated and friable; its color is a dark reddish brown. To obtain a correct idea of its shape, you might compare it to a wedge, the base of which is directed to the right, and thin edge toward the left.
The liver has five surfaces, superior, inferior, anterior, posterior and right lateral.
The liver has five lobes, right and left, caudate, quadrate, and lobus spigelii. It has five ligaments, right and left lateral or triangular, falciform, coronary and round. The liver has five fissures, the umbilical, the fissure of the ductus venosus, the transverse fissure, the fissure for the gall bladder, the fissure for the vena cava. These fissures can be represented by the letter H.
