With this new supply of nutritious matter, theblood goes to the heart and lungs to be oxygenized by contactwith the air, and thus be continued through the heart and arteriesas before explained. The system takes up its material for its wearand tear through the capillaries or hair-like tubes, which are inter-posed between the two great divisions of the vascular system, ar-teries and veins. These little tubes are so small that they arefrom looo to 4 0^0 0 of an inch in diameter. The smaller are foundin the retina of the eye and brain, the larger in the liver and.
