Assessing Renal System Flashcards
(30 cards)
Regulate body fluids (water, electrolytes, blood, pH)
Renal System Function
2 Hormones produced by the kidney
Vitamin D and Erythropoietin
Releases renin
Vitamin D
a hormone that increases BP
Renin
increases RBC production
Erythropoietin
Three regions of the kidney
Cortex, medulla, Pelvis
middle layer of the kidney
Medulla
Outermost layer of the kidney
Cortex
Innermost layer of the kidney
Pelvis
Normal GFR in adults
120-125 mL/minute
Formation of Urine
Glomerular Filtration, Tubular reabsorption, Tubular secretion
Influenced by number of functional nephrons, permeability of filtration membrane, net filtration pressure
Glomerular Filtration
Can be active or passive. Fluid moves from renal tubules into the capillaries
Tubular reabsorption
Reabsorption in reverse. Fluid moves from the capillaries into the renal tubules
Tubular secretion
Composition of urine
95% water and 5% solutes
Bilateral tubes that transport urine from the kidney to the bladder
Ureters
storage of urine
Bladder
Bladder
Found anteriorly in females, superior to the prostate in men
3 layers of bladder
Inner mucosa, detrusor muscle, outer membrane
It channels urine outside of the body
Urethra
Sympathetic Nervous System
Sphincter is constricted, bladder is relaxed
Parasympathetic Nervous System
Sphincter is relaxed, bladder is contracted
Other term for urination
Micturition/Voiding
