Bladder anatomy. Historical illustration of a section (at top) through a man's lower abdomen, showing the bladder (pale red) and other internal organs including the prostate gland (orange) and the rectum (dark red). The rectum stores faeces from the digestive system. The bladder stores urine excreted from the kidneys. The faeces and urine are expelled from the body via the anus and urethra respectively. Front (lower left) and rear (lower right) views of the bladder are at bottom. In the front view the urethra (brown) is seen leading out from the base of the bladder. Colour lithograph by Fairland from The Viscera of the Human Body, 1840. Based on drawings by Bagg.
