1 EXCRETORY SYSTEM By: Chayla, Chloe, Meagan, and Rhys

2 What is the excretory system? And The main function  Removes excess unnecessary materials from an organism  The removal of excess materials helps maintain homeostasis (an organism that prevents damage to the body)  Most healthy organs produce waste for the body to excrete  The main function is it removes waste products of the metabolism from body tissues to prevent damage

3 Organs, Tissues Affected  Kidneys- removes nitrogenous wastes from the blood, salts and extra water is removed and excreted in the form of urine  Liver- breaks down poisons and toxins, the liver can produce urea which is sent to the kidneys to be made into urine and the liver can make bile  Bile- after being produced in the liver its stored in the gall bladder where it is sent to the small intestine

4 Organs, Tissues Affected (continued) Which breaks down into harmless substances  Large Intestine- collects waste from throughout the body and transports it through 5 feet of intestine and then goes to tubes to be excreted  Skin- moves sweat through glands to rid your body of extra wastes

5 How the Excretory System Works Together The digestive system digests food which are broken down into things like glucose. The glucose is circulated through the blood into the muscular system and then is used for aerobic respiration. For aerobic respiration your muscles need oxygen. The oxygen is carried to other parts of the body to certain cells. The cells give off carbon dioxide which is then taken back to the lungs and the excretory system gets rid of the carbon dioxide.

6 Problems and Dysfunctions If the excretory system doesn’t work properly the toxins won’t be released and eventually this will lead to death. If only one part of the system fails, the toxins won’t be able to filter and after the toxins get stored in the blood, the blood will circulate around the body bringing diseases with it and around the body, eventually this will lead to death. Another problem about this system is if the person can’t perspire, when exercising there won’t be sweat to cool the person down, which can make the person tire quickly. As the sweat releases the excess sodium from the body, the body will eventually have too much sodium which will lead to high blood pressure and other problems in the body.

7 Common Diseases  Kidney Stones are hard masses that form in the urinary system from crystals that separated from the urine. Symptoms of kidney stones include extreme pain, cramping in the back and lower abdomen, nausea and vomiting.  Pyelonephritis is a type of urinary tract infection that travels to the kidneys from the urethra or bladder. The infection occurs when bacteria enters the body through the urinary tract. Symptoms include fever, pain in the groin, abdominal pain, and blood in urine.  Urethritis is an inflammation of the urethra caused by the same microbes that cause urinary tract infections. Symptoms vary between genders. Symptoms in men include blood in the urine or burning during urination, frequent urination. Symptoms for women include abdominal pain, fever, chills, frequent urination, and pain in the pelvis.
