 * The excretory system is the system in the body that collects wastes produced by cell and removes the wastes.The removal process is excretion. **


 * The four parts of the excretory system that break down and eliminate waste are the Kidneys, Ureters, Urinary Bladder, and the Urethra.**


 * Urine flows from the kidneys through two narrow tubes called ureters. The ureters carry the urine to the urinary bladder, a sacklike muscular organ that store **
 * urine. Urine flows from the body through a small tube called the urethra. Each kidney contains about a million nephrons. Nephrons are tiny structures that remove wastes from blood and produce urine. The nephrons filter wastes in stages. **


 * Blood enters the kidneys and then flows through branching arteries into a cluster of capillaries in a nephron. The capillaries are surrounded by a hollow capsule that is connected to a tube. In the capillary cluster, urea, water, and glucose move out of the blood and into the capsule. Blood cwells and most protein molecules do not move into the capsule. Instead, they remain in the capillaries. From the capsule, the filtered substances pass into a long, twisting tube. As the filtered material moves through the tube, most of the water and glucose are reabsorbed into the blood. Most of the urea remains in the tube. **


 * Some medical problems can be detected by analyzing the chemicals in urine. Glucose in the urine may indicate that a person has diabetes. Protein in urine can be a sign that the kidneys are not functioning properly. **
