Such are the properties of
the windpipe, and it takes in and throws out air only, and takes in
nothing else either dry or liquid, or else it causes you pain until
you shall have coughed up whatever may have gone down.
The oesophagus communicates at the top with the mouth, close to
the windpipe, and is attached to the backbone and the windpipe by
membranous ligaments, and at last finds its way through the midriff
into the belly. It is composed of flesh-like substance, and is elastic
both lengthways and breadthways.
The stomach of man resembles that of a dog; for it is not much
bigger than the bowel, but is somewhat like a bowel of more than usual
width; then comes the bowel, single, convoluted, moderately wide.
The lower part of the gut is like that of a pig; for it is broad,
and the part from it to the buttocks is thick and short. The caul,
or great omentum, is attached to the middle of the stomach, and
consists of a fatty membrane, as is the case with all other animals
whose stomachs are single and which have teeth in both jaws.
The mesentery is over the bowels; this also is membranous and
broad, and turns to fat. It is attached to the great vein and the
aorta, and there run through it a number of veins closely packed
together, extending towards the region of the bowels, beginning
above and ending below.
