The Urinary System
NWTC
Medical Terminology
1
Function




Maintaining Homeostasis
Constantly filtering blood to remove
urea and other waste products
Maintaining the proper balance of
water, salts, and other substances by
removing or reabsorbing them as
needed
Excreting the waste products via the
urine
NWTC

Anatomy & Physiology
 Urine is formed in the kidneys
 Ureters carry the urine to the
bladder
 Bladder is a temporary
reservoir for the urine
 Urine is excreted through the
urethra

Anatomy & Physiology
Function of the Kidneys







Maintain the chemical composition of the blood by
selective secretion of solutes
Maintain blood pH, thus contributing to acid base
balance
Excretion of nitrogenous waste products of protein
metabolism, mainly urea, uric acid, and creatinine
Degrade insulin
Metabolize Vitamin D to its active form
Production of renin, erythropoietin, and
prostaglandins
Maintain plasma volume by varying the
excretion of water

Nephr(o)
Kidney
Nephron
Functional unit of kidney comprised of a
glomerulus and tubules.
Glomerulus is a cluster of blood vessels
surrounded by Bowman's capsule
NWTC
Medical Terminology

Anatomy & Physiology





NWTC
Glomerulus
Filter for the blood
Bowman’s capsule collects the substances
that filter through the glomerular walls and
passes them through a long twisting tube.
The renal tubule is a long twisting tubule that
consists of a proximal tubule, a loop of Henle,
and a distal tubule that opens into a collecting
duct.
The function of the nephron is to filter blood
and reabsorption of the substances that the
body conserves.
Medical Terminology
9
Anatomy & Physiology




NWTC
Waste products and some of remaining
water in the tubules after reabsorption
combine to become urine
This urine passes through the collecting
duct to the renal pelvis
From renal pelvis urine passes through
the ureters to the bladder
Bladder – collapsible muscular bag that
serves as a reservoir for urine
Medical Terminology
10
Anatomy & Physiology



NWTC
Healthy bladder can hold 500 ml ( 1
pint) or more
Micturition, voiding, urination –
expelling urine form the bladder
Glomerular filtration rate (GFR)
calculates the volume of fluid filtered by
the glomeruli

Case Study
Last week, my neighbor Mrs. O. was
complaining of back pain, blood in her
urine, and painful urination. She went to
see the physician who specializes in
urinary problems. The physician ordered
a urine test. It was found that she had
albumin in her urine. The physician then
ordered a ultrasonic scanning of the
kidney. She was diagnosed with kidney
stones and an enlarged left kidney.

Case Study
The physician spoke with Mrs. O. and
decided she needed to have the kidney
stones surgically crushed. Mrs.. O. had to
have a tube inserted into her bladder to
drain urine. Mrs. O. is now home and
happy to be with her family.
