17. 3 The Urinary System Nutritional Unit

Functions Filter liquid waste and extra fluid from the blood.

Urine Liquid waste excreted from the body in the process known as urination. -Consists of water, nitrogenous waste, and salts. - Nitrogenous waste contains nitrogen from the break down of PROTEINS. Nitrogen will kill cells even in small amounts.

Structures Kidneys: two bean shaped organs the size of a fist. Located near the middle of the back just below the rib cage. Kidneys are in charge of filtering out the liquid waste from the blood.

Structures Kidneys: two bean shaped organs the size of a fist.

Structures Ureters- Tubes that connect the kidney to the bladder. Muscle contractions continuously send urine from the kidney through the ureters to the bladder.

Structures Bladder: Hollow muscular organ that acts as a reservoir (storage unit) for urine.

Structures Urethra: The tube that leads from the bladder to the outside of the body. A sphincter will open when ready to urinate. Girls: only about 2 inches in length. Boys: a few inches longer than the length of the penis.

Structures Urethra: The tube that leads from the bladder to the outside of the body.

Healthy Behaviors Drink at least _____ oz of water per day. Eat a well balanced meal. Too much protein will place extra effort on the kidneys Practice good hygiene and personal health care Wipe from front to back. Extra bacteria around the Urethra can cause an infection.

Healthy Behaviors Tell your doctor about any changes in frequency, color, or smell.

Problems Cystitis (bladder infection): inflammation the bladder. Usually due to a bacterial infection Urethritis (Urinary Tract Infection-UTI) inflammation of the urethra Usually due to a bacterial infection Burning pain during urination Fever Presence of blood in urine

Problems Kidney Problems: Nephritis- Inflammation of the Nephrons (working part of the kidney) Kidney Stones- Salts in the urine crystalizes. Painful when passed Sometimes high- intensity waves are used to break stones down. Surgery may be needed.

Problems Kidney Problems:

Problems Kidney Problems: Uremia: decrease in blood filtration and an increase in Nitrogenous waste in the body causing wide spread tissue damage.

Problems Kidney FAILURE: Acute: Sudden Onset Chronic: Kidneys slowly lose ability to filter blood. Dialysis: a machine takes out your blood and filters it. Transplant: A third kidney is introduced to the front of your abdomen to take over filtration.
