Urinary System 224 Flashcards
A major part of homeostasis is maintaining
the composition, pH, and volume of body fluids within normal limits
The urinary system removes
metabolic wastes and substances in excess, including foreign substances like drugs and their metabolites that may be toxic
Urinary consists of:
a pair of kidneys
a pair of ureters
a urinary bladder
A urethra
Three Functions of the Urinary System
1-EXCRETION (Removal of organic wastes from body fluid)
2-ELIMINATION (Discharge of waste products)
3: Homeostatic regulation
(Of blood plasma volume and solute concentration)
Function of kidney
Organ that produces urine
Urinary tract are organs that eliminate urine through
•Ureters (paired tubes)
•Urinary bladder (muscular sac)
•Urethra (exit tube)
Urination or micturition is
process of eliminating urine
-Contraction of muscular urinary bladder forces urine through urethra, and out of body
Ureter function
Transports urine towards the urinary bladder
Urinary bladder function
Temporarily stores urine prior to elimination
Urethra function
Conducts urine to exterior; in males, transports semen as well as
Hormone that decreases sodium reabsorption in the kidneys is called
ANP
Movement of bonfires substances from the blood to the filtrate is called tubular
Secretion
Several minor calyces merge to form the
Major calyx
What are functions of the distal convoluted tubule and collecting duct
-transport of sodium and chloride ions
-reabsorption of water
Within renal corpuscle, is the BCOP an inward pressure drawing fluid into the capillaries or an outward pressure forcing fluid out of the capillaries into the glomerular capsule?
Inward
