Add: Urethra 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.<http://m.newhealthadvisor.com/excretory-system-organs.html>

Add: Ureters The ureters tubes of smooth muscle fiber transfer liquid waste from the kidneys into the urinary bladder. 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.<http://m.newhealthadvisor.com/excretory-system-organs.html>

Add: Large Intestine 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.<http://m.newhealthadvisor.com/excretory-system-organs.html> Wondering woman (talk) 00:03, 23 July 2017 (UTC)

The undigested food comes out in the form of faeces but it could not be considered as excretion as excretion means passing out nitrogenous waste. ChetanpreetKaur (talk) 15:48, 14 December 2017 (UTC)

Not done: please provide reliable sources that support the change you want to be made. Specifically, provide sources that establish that "excretion" always refers to nitrogenous waste". Eggishorn (talk) (contrib) 16:26, 14 December 2017 (UTC)

Defaecation means passing out undigested food (faeces) from the intestine , so it cannot be considered as excretion because excretion means passing out nitrogenous waste. Similarily, passing out carbon dioxide through lungs is a part of respiration and not excretion. Excretion by sweat glands is incidental. These glands are primarily concerned with cooling(thermoregulation). The sweat secreted carries with it small amounts of nitrogenous wastes. Sweat Glands pass out sweat only when it is required, so truly they are not excretory. ChetanpreetKaur (talk) 15:58, 14 December 2017 (UTC)
