    The origin of the veins is in the capillary system. portae are readily detected, by the expanded state ol their orifices. The vena portae arises from that division of the abdominal capillary system, connected with the gastric apparatus, commencing between the coats of the stomach, intestines, &c. and terminating by inosculation with the capillaries of the hepatic veins. The blood, therefore, is conveyed from all the chylopoietic viscera by numerous veins, which unite to form one large trunk, the vena portae ; which after a course of about two or three inches, arrives at the transverse fissure of the liver, (where it divides into a right and left branch,) and then enters the corresponding lobes, spreading out into branches, and ramifying in their structure. But the veins from the kidneys, and the pelvic viscera, are totally excluded from any commu- nication with this vein, which preserves its inte- grity and independence- throughout its course. The blood, distributed by these vessels in the liver, is collected again, and carried into the vena cava inferior, by the hepatic veins. Thus then it has been made to appear, that the veins take their origin in the general capillary system; of which nothing can be stated posi- tively, as the result of observation and experiment, by reason of their extreme tenuity; but it is probable, that as they are so intimately interwoven with the structure of organs, they partake, in some measure, of their respective textures.
