Urinary EliminationScientific Knowledge BaseUrinary elimination is the last step in the removal and elimination of excess water and by products of body metabolism. Adequate elimination depends on the coordinated function of _________________________, __________________, ___________________, and _________. The kidneys filter waste products of metabolism from the blood. The ______________________________________ from the kidneys to the bladder. The bladder holds urine until the volume in the bladder triggers a sensation of urge indicating the need to pass urine. Micturition occurs when the brain gives the bladder permission to empty, the bladder contracts, the urinary sphincter relaxes, and urine leaves the body through the urethra.KidneyThe kidneys lie on either side of the vertebral column behind the peritoneum and against the deep muscles of the back. Normally the left kidney is higher than the right because of the anatomical position of the liver.Nephrons, the functional unit of the kidneys, remove waste products from the blood and play a major role in the regulation of fluid and electrolyte balance. The normal range of urine production is ______________________________. Please convert to CC/day. Erythropoietin, produced by the kidneys, stimulates red blood cell (RBC) production and maturation in bone marrow. The kidneys play a major role in blood pressure control via the renin-angiotensin system, release of aldosterone and prostacyclin. The kidneys also affect calcium and phosphate regulation by producing a substance that converts vitamin D into its active form.UretersA ureter is attached to each kidney pelvis and carries urinary wastes to the bladder.BladderThe urinary bladder is a hollow, distensible, muscular organ that holds urine. The bladder has two portions, a fixed base called the trigone and a distensible body called the detrusor. The bladder expands as it fills with urine. How much urine can the bladder hold?UrethraUrine travels from the bladder through the urethra and passes to the outside of the body through the urethral meatus. The urethra passes through a thick layer of skeletal muscles called the pelvic floor muscles. These muscles stabilize the urethra and contribute to urinary continence. The external urethral sphincter, made up of striated muscles, contributes to voluntary control over the flow of urine. The female urethra is approximately 3 to 4 cm (1 to 1.5 in) long and the male urethra is about 18 to 20 cm (7 to 8 in) long. The shorter length of the female urethra increases risk for urinary tract infection due to close access to the bacteria contaminated perineal area.Act of UrinationBrain structures influence bladder function.Voiding: Bladder contraction + urethral sphincter and pelvic floor muscle relaxationBladder wall stretching signals micturition center.Impulses from the micturition center in the brain respond to or ignore this urge, thus making urination under voluntary control.When a person is ready to void, the central nervous system sends a message to the micturition centers, the external sphincter relaxes and the bladder empties.Factors Influencing Urination (See Box 46-1)Growth and development_________________________________________________________Sociocultural factors_________________________________________________________Psychological factors_________________________________________________________Personal habits_________________________________________________________Fluid intake_________________________________________________________Pathological conditions_________________________________________________________Surgical procedures_________________________________________________________Medications_________________________________________________________Diagnostic Examinations_________________________________________________________Common Urinary Elimination ProblemsThe most common problems involve _____________________________________________ or ________________________________________.
