In each sac, the outer wall of the tube has grown inward and carried with it a very tiny artery. This artery breaks up into a mass of capillaries. These capillaries, in turn, unite to form a small vein as they leave the little sac. Each of these sacs with its contained blood vessels is called a glomerulus.

In the fishes it appears in the embryo but is replaced by the second devel- opment, the MESONEPHRos (Fig. 130). This consists of a considerable number of collecting ducts, each with a special excretory organ, the GLOMERULUS. The collecting ducts open into a mesonephric duct, which is in reality the reorganized pronephric duct; it delivers the wastes into the common receptacle, the cloaca. In vertebrates high

In the region of the CONVOLUTED TUBULE Certain important salts and water are resorbed back into the blood. The remainder of the contents are carried along, and the duct joins with other ducts. These pass through the medullary portion of the kidney and empty into a re- ceptacle, termed the renal pelvis. From the renal pelvis a tube, the URETER, leads downward to enter the base of the urinary bladder. ARTERY AND VEIN

The efferent vessel leaves the glomerulus and breaks up again into capillaries which supply the walls of the convoluted tubules. Thus the arrangement of the portal system of vessels is repeated in the kidney on a microscopic scale—the vessel taking the blood from the glomerulus breaks up again into a system of capillaries, just as the portal vein does in the liver. The pyramids are supplied by branches of the vasa recta which pass inwards from the arteries in the boundary zo
