The intestines take origin from the stomach; of them, that which is called rectum and _longanon_[7] is the lowest of all the intestines and contains the dry burden of the bowel, and its head extends outward between the nates so that it may dispose of its burden. The colon is continuous with it and in its ascent goes around the left kidney, and at the sides of the stomach it falls away to the right.[8] What the Greeks call TYPHLON and MONOPHTHALMON, the Romans the blind intestine and one-eyed,[9] is attached to the colon, of which it is the only passage; for the other end is closed so that it may assist coction more suitably in the manner of the stomach. Hence the name for the thing. And such is the number of the thicker intestines. The caecum is continuous with the ileon,[10] an intestine twisted into numerous sinuses; from its shape the Greeks gave it the name PARA TOU EILEISTHAI, that is, from its involvement; and its disease is called _iliacus_. The jejunum follows it. Dissectors of bodies gave this name jejunum to the latter intestine because of the fact that it is always found empty and contains nothing. For the liver first snatches away whatever the jejunum might contain. Above all these intestines arises the duodenum which is continuous below with the jejunum and above with the pylorus. It is called DŌDEKA DAKTYLOM by the Greeks from the measure of twelve fingers. These three [intestines] by reason of their substance are called the slender intestines. The stomach is located under the diaphragm, of which the upper mouth ends in the oesophagus, properly called _stomachus_; the lower opening through which aliment is sent into the intestines is called PYLŌROS. The spleen is an organ of rare substance and lies at the left side of the stomach; the liver being in the right hypochondrium. The latter is rounded and to some degree lunate, the former longish and somewhat quadrate. The gibbous part[11] of each of these extends toward the lower ribs, because there is a concavity in each of them which is very close to the stomach. The liver gives rise to the blood.[12] The spleen purges it of black bile. The spleen increases with loss to the rest of the body. The size of the liver is useful to the whole bodily structure, because it provides copious blood and natural spirit. The liver has lobes which the Greeks call LOBOUS, sometimes three, sometimes more,[13] and in its hollow extends the gall bladder by which the blood is freed of bile and issues forth pure. It is especially by exhalation and transpiration of this bladder that the duodenum and jejunum are sometimes stained;[14] sometimes they are irritated if there is a very large transpiration of particularly corrosive bile.
