An organism can minimize the potential damage of absorbed toxins by excreting the chemical or by changing the chemical into a different chemical biotransformation , or by both methods. The body can excrete exogenous chemicals in the urine, bile, sweat, or milk; the lungs can….
The blood carries the waste products of cellular metabolism to the excretory organs. The removal of carbon dioxide via the lungs has been described above. Water produced by the oxidation of foods or available from other sources in excess of needs is excreted by…. The main route of drug excretion is through the kidneys; however, volatile and gaseous agents are excreted by the lungs. Small quantities of drugs may pass into sweat, saliva, and breast milk, the latter being potentially important in breast-feeding mothers.
Some chemicals, rapidly excreted in the urine, must act quickly while they remain transiently in the body. Others are poorly eliminated, and, because of this, a chronic ingestion of nontoxic amounts leads to a buildup in the body that can reach toxic….

The urine is moved with peristaltic movements which force the urine away from the kidneys. The ureters also have ureterovesical valves which ensure the waste fluid does not travel back into the kidney. The urethra runs through the penis in males, and serves as a carrier of semen as well as urine for their ultimate discharge out of the body.
The urethra tube is shorter in females and is just above the vaginal opening. Food particles are absorbed into the blood stream via the small intestine. The undigested substances are transferred to the large intestine which essentially serves as a storage organ for the excretory products.
The descending, ascending and transverse colons also facilitate the absorption of leftover vitamins, water and salt. The distal straight section known as the rectum is used for the storage of waste products feces before they are excreted from the body via the anal canal with the help of internal and external sphincters.
Kidney stones are believed to form from crystals that have separated from urine, forming hard masses in the urinary tract, though the exact cause is unknown. Symptoms for kidney stones include extreme pain, cramping in the lower abdominals and back, nausea, and vomiting.
Most kidney stones can be passed by increasing your intake of water to flush them out, although surgery may be needed in some cases. Urethritis is a viral or bacterial infection that causes inflammation of the urethra. Symptoms for urethritis vary between the sexes. Pyelonephritis is a type of urinary tract infection that travels from the urethra or bladder and to the kidneys. This infection occurs when bacteria enter the body through the urinary tract.
Symptoms include frequent urination, burning during urination, blood in the urine, pain in the groin and abdominal pain. Pyelonephritis is usually treated with oral anti-biotics, although the anti-biotics are sometimes administered intravenously in cases of severe infections. Cystitis is the medical term for inflammation of the bladder and it is one of the most common disease that affects excretory system organs.
As the bladder stores urine before it is excreted from the body, bacteria can build up in the bladder and cause cystitis. Urinary tract infection UTI is the infection of the urethra or the bladder. Proper nutrition supports all of these advancements. As your little one becomes a toddler, he can still get these immune-nourishing benefits.
