The document discusses the human excretory system. It explains that the excretory system removes cellular waste from the body through various organs. It identifies the liver, lungs, skin, and kidneys as major excretory organs. The liver excretes bile and converts nitrogenous waste to urea. The lungs excrete carbon dioxide and water. The skin excretes waste through sweat glands. The kidneys are identified as the primary excretory organ and the major component of the urinary system, which also includes the ureters, bladder, and urethra.

fails the other organs cannot take over and
compensate adequately.
