1. Kidneys
2. Ureters
3. Bladder
,4. Urethra
5. Pelvic floor
How do medications affect urination?
1. Meds affecting ANS cause retention
2. Diuretics increase urine formation by preventing reabsorption of water & electrolytes
How does muscle tone affect urination?
Muscle tone is needed to maintain the stretch & contractility of the detrusor muscle so the
bladder can fill & empty completely
What is the difference between stress & urge incontinence?
Stress: loss of urine control during activities that increase intra-abdominal pressure
(coughing, sneezing, laughing, or exercise)
Urge: a sudden strong urge to void, followed by a rapid bladder contraction

What is insensible fluid loss?
The amount of fluid lost on a daily basis from the lungs, skin, respiratory tract, and water
excreted in the feces; the exact amount cannot be measured

Fluid loss that is required to maintain normal body function; necessary for temp regulation
and elimination of waste products

6-8 times a day
How does ADH increase water reabsorption into the blood? (5)
1. Blood osmolality increases
2. Osmoreceptors in hypothalamus stimulate posterior pituitary to secrete ADH
3. ADH increases distal tubule permeability
4. Increase of water reabsorption of H2O
5. Urine output decreases
