arterye hathe hys beginnynge from the hearte, so hathe
the veyne his beginnynge from the lyuer: and it bryn∣geth
from thence nutrityue bloude, vnto all the mem∣bers
of the bodye, to nourishe them wyth. And I vnder∣stande
as well by experyence, as by that whiche I reade,
that there is no more difference betwene the veyne and
the arterye, but that one (hauynge two coates, and com∣mynge
from the hearte,) is the vessell of vitall and spiri∣tuall
bloude, and the other (hauynge but one coate, com∣mynge
from the lyuer,) is the vessell of nutritiue bloud.
And thys is generally in all veines, except only the arteri∣all
veyn•• whych (as in the seuenth Chapiter I sayd) pro∣cedeth
immediatlye from the hearte.
And amonge all the veines there are two moste pryn∣cipalle,
from whyche the braunches of all the reast procede:
that is to saye, Vena porta, and Vena Coele, whiche some calle
Vena Caua, ••r Magna, and these two haue their beginnings
in the lyuer. I fynde ••n Regi••ine sanitatis salerni, the num∣ber
of veines in mannes bodye to be three hundreth, thre
score, and fyue wyth these woordes. (Ex tricentenis decies
〈…〉〈…〉 But I thyncke thys number to be
mente of ••••tay••e notable veynes, whyche by order of
Anatomye, maye be made open to the senses, and not
precyselye of all: for they braunche oute into innumera∣ble
braunches, tyll they come to the verye smalnesse of
heares, as it maye be perceyued in the pannicles, and
some thyn skynnes, as the eye lyddes, and the skyn of the
yarde, and diuers other places, and are therefore called
Venae Capillares.
