Their chief office, however, is to retard the flow of blood, andthus give time for the tissues to select from the blood the nutrimentmost suited for them. There were no valves in the arteries, whichhad thick and strong walls, and were not liable to distension. Thatvalves are absent in some great veins connected with importantorgans is to allow free access of blood to these organs. The figurewe have reproduced shows the arm bound with a fillet, as forbleeding; the veins are swollen, and the position of the valvesindicated by slight bulgings, exactly as was figured by Harvey. Theother figure shows an everted vein, with its valves. In the originalthere is a sprig of verbena. How different the uses made of the same.
