Riolanus speaks of the region outside the liver, to which the branches of the portal vein are distributed, as the "first region." The "second and third regions" appear to comprise all the rest of the body. See Harvey: Exercise to Riolanus, I, Syd. 90, l. 30 to 91, l. 23; Op. Omn. 92, l. 21 to 93, l. 18.
