Uroscopy - Uroscopi

Japanese: ウロスコピー - うろすこぴー

…Unnecessary substances contained in an animal's body fluids are excreted from the body along with water through the excretory organs. Vertebrates have kidneys that are developed as excretory organs. In mammals, urine produced in the kidneys is collected in the bladder through the ureters and is excreted intermittently through the ureters. The types and amounts of substances reabsorbed and secreted are regulated mainly by hormones (aldosterone, vasopressin, etc.) in relation to the osmotic pressure and ion regulation of the body fluids, resulting in urine of an appropriate concentration. Animals that live in environments that are more hypertonic than the body fluids, such as saltwater fish, produce relatively concentrated urine, while freshwater animals produce urine that is paler than the body fluids. …
