Urinary System Review Flashcards
Functions of the urinary system
regulatory- mainly things in blood
hormone production
waste excretion
What is the functional unit of the kidney?
nephron
The ____ kidney is lower than the ____ kidney
right, left
A layer of fat, called what cushions, protects, and supports each kidney?
adipose capsule
the regions of the kidney include the outer region ___, inner region ___, and inner collecting area ___.
renal cortex
renal medulla
renal pelvis
Kidney structures : triangular regions of tissue in the medulla
renal pyraminds
Kidney structures : extensions of cortex-like material inward
renal columns
Kidney structures : cup shaped structures that funnel urine into renal pelvis
calyces
blood flow to the kidneys arts in the ___ artery to the entire kidney
renal
blood flow to each nephron is through the ___ ___.
interlobular artery
afferent arteriole
the ball of capillaries in the nephron is the ___
glomerulus
the ___ arteriole drains the nephron
efferent
the ___ ___ drains blood from the kidney
renal vein
the main parts of a nephron are : ___ captures filtrate from glomerulus
glomerular capsule (bowman’s capsule)
the main parts of a nephron are : ___ reabsorbs most materials
proximal convoluted tubules
the main parts of a nephron are : ___ reabsorbs water & salt making urine more dilute
convoluted tubules (proximal and distal)
the main parts of a nephron are : __ balances electrolytes
nephron
the 3 urine formation processes are: ______ formation of fluid by the glomerulus
glomerular fitration
the 3 urine formation processes are: ____ return of needed substances to blood
tubular reabsorption
the 3 urine formation processes are: ____ active removal of wastes from blood into tubules
tubular secretion
Normal output rate of urine?
1-2 Liters/day
inner wall folds of the bladder is also called?
rugae
What are some symptoms of one experiencing renal failure?
nausea, extreme bloating, yellow eyeballs, lack of urine produced
maintains water and electrolyte balance of blood
kidnet
serves as a storage area for urine
urinary bladder
transports urine to the body exterior
urethra
transports arterial blood to the kidney
renal artery
produces urine
kidney
smooth membrane clinging tightly to kidney surface
renal capsule
portion of kidney containing mostly collecting ducts
renal medulla
portion of kidney containing bulk of the nephron structures
renal cortex
basinlike area of the kidney, continuous with ureter
renal pelvis
