THE LIVER.
This organ is also essential to digestion; it furnishes the bile; it is the largest gland in the body, and its office seems to be to gather from and carry out of the system substances which, if retained, might prove hurtful. When the liver is inactive, we have what is called the jaundice; the liver failing to take up from the system that substance which forms the bile. When this is the case, a yellow substance is found diffused throughout the whole body, and it exhibits a yellow tinge. The bile, when properly secreted and discharged, meets the contents of the stomach as discharged into that part of the bowels nearest the stomach, and is there supposed to assist in the process of separating the nutritious part of the contents from the refuse, which is to pass off by the bowels; but its more important office is, doubtless, to rid the passage of the refuse, or the fæces, by evacuation. The bile seems to be nature’s appropriate stimulus to the bowels, without which costiveness, and other irregularities, are likely to ensue.
