1272 THE UKINO-GENITAL SYSTEM. The urethra, or canal by which the urine reaches the surface, leads from the bladder, its aperture lying in the median plane, not far from the openings of the ureters,'but on a lower and anterior plane. The size and shape of the bladder, the thickness of its wall, and also to a great extent its relations, vary with the amount of distension, or contraction, of the organ. When the bladder is empty, or only slightly distended, it lies within the pelvic cavity; as it becomes filled with urine it rises above the pubis, and crossing the pelvic brim, enters the Ductus deferen Inferior epigastric artery Superior peritoneal li of bladder --' Urinary bladder Sacro-genital fold Kecto-vesical pouch Ductus deferens Retro-pubic pad of fat Prostatic urethra Dorsal vein of penis Corpus cavernosnm penis Corpus cavernosum urethra

The coils of small intestine have been removed to afford a view of the lateral wall of the pelvic cavity. abdominal cavity. These changes affect chiefly the upper part of the bladder, which becomes altered in shape and size, and acquires new connexions and relations; the lower portion varies but slightly with the amount of distension of the organ (see Figs. 989 and 990). The upper part of the bladder is covered by peritoneum, which is reflected on to it from the anterior abdominal wall in front, from the sides of the pelvis laterally, and, in the male, across the seminal vesicles and terminal parts of the ductus deferentes from the rectum behind. In the female the peritoneum passes on to the bladder posteriorly from the anterior surface of the uterus. The peritoneum dips down posteriorly for a certain distance between the bladder and
