Study Notes
Kidney Function and Elimination
- Kidneys maintain body fluid volume and composition
- Filter waste products
- Regulate blood pressure and acid-base balance
- Produce erythropoietin (RBC production)
- Convert vitamin D to its active form
- Ureters, bladder, and urethra are the drainage routes for urine excretion
Kidney Anatomy and Physiology in Adults
- Located retroperitoneally, behind the peritoneal cavity
- In adults, 4-5 inches long, 2-3 inches wide, 1 inch thick
- Weighs about 8 oz (250 g)
- Left kidney is slightly longer than the right
Kidney Functions
- Glomerular filtration is the first step in urine formation
- Filtration rate is about 180 liters/day.
- The average normal glomerular filtration rate (GFR) is 125 mL/minute
- About 1 to 3 liters of urine is excreted daily
Tubular Reabsorption
- Second process in urine formation
- Reabsorption maintains normal urine output (1-3 L/day)
- Prevents dehydration
- Influenced by hormones such as ADH and aldosterone
Other Important Kidney Functions
- Regulation of blood pressure and fluid volume
- Removal of waste products
- Maintaining electrolyte homeostasis and acid-base balance
- Erythropoietin production for red blood cell synthesis
- Vitamin D activation
Hormonal Influences
- Antidiuretic hormone (ADH) and aldosterone regulate urine concentration and volume.
- They affect fluid and electrolyte balance.
Changes in Kidney Function with Age
- Cortical tissue loss reduces kidney size
- Reduced renal blood flow impacts filtration ability
- Glomerular filtration rate (GFR) decreases with age, more drastically after age 45, impacting waste removal and fluid balance.
- Urinary concentration capacity declines, increasing risk of dehydration and hypernatremia.
- Changes in hormone levels (renin, aldosterone, vitamin D) can impact kidney function
Renal/Urinary System Changes Associated with Aging
- Decreased renal blood flow
- Thickening of blood vessels
- Reduced kidney size impacting filtration process
- Urinary concentration ability is reduced, leading to nocturia (increased urination at night)
