Urinary System Test Questions with
Verified Answers
kidney function - Ans -produces urine, removes wastes while retaining water,
nutrients, and ions
urinary system functions - Ans -regulation of blood ionic composition (Na, K, Ca, Cl,
phosphate)
regulation of blood pH
regulation of blood volume/blood pressure
regulation of blood glucose levels
excretion of wastes and foreign substances
Nephron function - Ans -glomerular filtration, tubular reabsorption, tubular secretion
Ureter function - Ans -Tubes that transport urine from kidneys to the bladder through
peristalsis
Bladder function - Ans -reservoir for urine before it leaves the body
aided by the urethra, it expels urine from the body
Urethra function - Ans -carries urine from the bladder to the outside of the body

What makes up the trigone? - Ans -three layers of smooth muscle called detrusor

What makes up the Renal Corpuscle? - Ans -glomerulus, bowman's capsule,
bowman's space

the glomerular capillaries
What is the approximate capacity of the bladder? - Ans -700-800 ml
What are renal calculi? - Ans -Kidney stones form in renal pelvis
Glomerular filtration rate - Ans -180 L/day
Glomerular filtration - Ans -pressure forces blood in the glomerulus and into
Bowman's space/capsule. This causes a separation based on size
