The veins and arteries proceed both from the hypogastric and the spermatic vessels, of which I shall speak by and by; all these are inserted and terminated in the proper membranes of the womb. The arteries supply it with food and nourishment, which being brought together in too great a quantity, sweats through the substance of it, and distils as it were a dew at the bottom of the cavity; from thence proceed the terms in ripe virgins, and the blood which nourisheth the embryo in breeding women. The branches which issue from the spermatic vessels, are inserted on each side of the bottom of the womb, and are much less than those which proceed from the hypogastrics, those being greater and bedewing the whole substance of it. There are some other small vessels, which arising the one from the other are conducted to the internal orifice, and by these, those that are pregnant purge away the superfluity of the terms when they happen to have more than is used in the nourishment of the infant: by which means nature has taken so much care of the womb, that during pregnancy it shall not be obliged to open itself for passing away those excrementitious humours, which, should it be forced to do, might often endanger abortion. As touching the nerves, they proceed from the brain, which furnishes all the inner parts of the lower belly in them, which is the true reason it hath so great a sympathy with the stomach, which is likewise very considerably furnished from the same part; so that the womb cannot be afflicted with any pain, but that the stomach is immediately sensible thereof, which is the cause of those loathings or frequent vomitings which happen to it.
