The larger branches of all these Systems are called Trunks, yvhen viewed in relation to their (fwn particular ramifications; a sort of language which, although incorrect, creates no confusion. The principal Trunks of the arteries are two; one commencing at each ventricle of the heart. The one commencing at the right or pulmonic ventricle, is named the Pulmonic Artery, from being ramified through the Pulmones ox lungs. It receives the blood upon its return from all different parts of the body, and which is then generally of a dark and livid colour, but on being exposed to the action of the air, in its passage through the lungs, assumes a colour that is florid red. The other, commencing at the left or systemic ventricle, is named the Aorta or Systemic Artery. It receives tlirough the course of its auricle and ventricle the florid blood return- ing from the numerous veins of the lungs, and af- terwards transmits it, through the medium of its branches, to the system at larg-e.
