Sphincter
urine is stored here until you're ready to urinate
bladder
which of the following should not be in urine
blood
The renal system does not play a direct role in regulating which of the following
blood temperature
what is a nephron
combination of glomerulus and renal tubule where filtration reabsorption and secretion take place in the kidney
healthiest habit for the urinary system is to
drink lots of water
sodium and potassium are
electrolytes regulated by kidneys so that a proper concentration is maintained within blood
what is the glomerular/Bowmans capsule
enclosing structure surrounding each Glomerulus
Urine is formed in a three-step process. which of the following gives the correct order in which these steps take place in the nephron
glomerular filtration, tubular reabsorption, tubular secretion
where does filtration of blood take place in the kidney
glomeruli
The presence of which of the following in urine even in small amounts is indicative of a possible problem in the renal system of a patient
glucose
where is the Madella located (loop of henle found here)
inner region of the kidney
in homeostasis the kidney regulates the
levels of electrolytes amount of water in the body ph
The functional unit of the kidney is the
nephron
water reabsorption as possible in the proximal tubule due to
osmosis
what is the kidney cortex
outer region of an organ
what best describes filtration
process were some substances but not all passed through a filter
The collecting duct is _____ takes place
reabsorption
the Glomerulus and renal tubule are found in
renal corpuscle
The blood vessel carry blood away from the aorta into the kidney is the
rental artery
kidney function is accomplished by all of these mechanisms
secretion filtration reabsorption
The renal sinus is
the entrance of the kidney
what is the glomerulus
tiny ball of blood vessel/capillaries located between the afferent and efferent arteries
The afferent arterial supplies blood to the capillaries of the glomerulus
true
The blood vessel that carries blood away from the kidney and toward the heart is a renal vein
true
each kidney has approximately 1 million nephrons
true
the kidneys function in filtering blood and releasing urine
true
urine flows from the kidneys to the ureters to the bladder in out the urethra
true
urine moves down the ureters of the urinary system through a process called peristalsis
true
the tube connecting each kidney to the urinary bladder is the
ureter
_____ is responsible for storing urine temporarily
urinary bladder
identify each system that would be found in the excretory system
urinary respiratory digestive integumentary
to maintain a healthy urinary system you must follow all of the following except
urinating in irrigation canals
