Excretory System

|| || The word excretion means the removal of waste substances from the body. Several organs are involved with the excretory system, including the kidneys, sweat glands, lungs . and rectum, The primary organs of excretions, however, are the kidney. Excretion is vital to the health of the body because the wastes are poisonous. If the wastes build up and are not eliminated, they can cause serious problems. As you know , carbon dioxide and water vapor are removed by the lungs. Other wastes , namely urea, uric acid, various salts, and assorted nitrogenous wastes , are removed by the kidneys and sweat glands.
Diseases and disorders that affect the excretory system include gout, kidney failure, urinary tract infections, diarrhea and constipation. Kidney failure occurs through the body's loss of kidney functions. When the kidneys fail, there is no filtering of the blood, which leads to a buildup of waste in the body
