The document discusses the human excretory system, which removes waste from the body through urine and sweat. It describes the key organs - kidneys, ureters, urinary bladder, urethra, liver, skin and lungs - and their functions. The kidneys balance salt levels in the body and produce urine, while the ureters and bladder store urine before it passes through the urethra. The liver converts ammonia to urine and the skin and lungs also remove waste, through sweat and exhaled carbon dioxide respectively.
