the voluntarily controlled sphincter fashioned by skeletal muscle at the point where the urethra passed through the pelvic floor is called the?
external urethral sphincter
which of these must you consciously relax for micturition to occur?
external urethral sphincter
urine moves down the ureters into the urinary bladder due to gravitational pull alone.
false
the inability to voluntarily control the external urethral sphincter is known as?
incontinence
which blood vessels are found in the renal columns?
interlobar artery and vein
the involuntary sphincter that keeps the urethra closed when urine is not being passed is called the?
internal uthrethral sphincter
the capillary bed surrounding the renal tubule is the?
peritubular capillaries
the blood vessel carrying blood from the aorta into the kidney is the?
renal artery
There are three regions of the kidney; the outermost region is known as the?
renal cortex
outer, lighter region of the kidney.
renal cortex
the smooth triangular region of the urinary bladder base that is outlined by the openings of the two ureters and the urethra is called the?
trigone
the kidneys are situated in a retroperitoneal position and found between the T12 and L3 vertebrae.
true
the tube connecting each kidney to the urinary bladder is the?
ureter
tube that drains urine from the kidney to the urinary bladder.
ureter
transports urine and sperm in males.
urethra
urine is transported from the urinary bladder to the outside of the body by the?
urethra
inflammation of the urethra is called?
urethritis
of the capillary beds associated with each nephron, the one that is both fed and drained by arterioles is the?
glomerulus
the blood vessel directly feeding the glomerulus with blood from the cortical radiate artery is the?
afferent arteriole
cup shaped-extensions of the pelvis that enclose the tips of the renal pyramids.
calyces
most nephrons are located within the renal?
cortex
the involuntary internal urethral sphincter is composed of skeletal muscle.
false
the peritubular capillary bed arises from the afferent arteriole.
false
the region of the renal tubule closest to the glomerular capsule is the distal convoluted tubule.
false
the structural and functional units of the kidney are the renal pyramids.
false
the uretha, which carries urine exiting the urinary bladder by peristalsis, is typically shorter in female than is males.
false
why is the trigone of the urinary bladder clinically important?
infections tend to persist in the trigone
which organ filters blood, regulates blood volume and chemical makeup?
kidney
the process of emptying the urinary bladder is known as voiding or?
micturition
the functional unit of the kidney that filters blood and forms urine is the?
nephron
what region if the kidney is deep into renal cortex?
renal medulla
flat, basinlike cavity medial to the renal hilum of the kidney.
renal pelvis
what part of the kidney attaches to the ureter?
renal pelvis
triangular regions with a striped appearance.
renal pyramids
blood is transported away from the kidney in this vessel.
renal vein
in males, the urethra is part of both the urinary system and?
reproductive system
which one of the following terms describes the location of the kidneys?
retroperitoneal
which of the following is NOT a correct description of the hilum of the kidney?
the hilum is in the most superior surface of the kidney
the urinary bladder is able to expand as urine acculumates within it due to the presence of?
transitional epithelium
micturition reflex causes this organ to go into contractions.
urinalysis bladder
muscular sac suitable for temporary urine storage.
urinalysis bladder
contains an area called the tribune formed by the openings of the ureters and urethra.
urinary bladder
contains three layers of smooth muscle known as the detrusor muscle.
urinary bladder
what causes the internal urethral sphincter to open?
pressure from the contracting bladder
which of the following is NOT one of the functions of the kidneys?
produce hormones that assist in digestion
starting from the glomerular capsule, the correct order of the renal tubule regions is?
proximal convoluted tubule, nephron loop (look if Henle), distal convoluted tubule
cortex-like extensions that separate the renal pyramids.
renal columns
There are three ferguson's of the kidney; the outermost region is known as the?
renal cortex
the medial indentation where the ureter, blood vessels, and nerves are connected to the kidney is called the?
renal hilum
darker, reddish-brown internal area of the kidney.
renal medulla
which bones provide some protection for the kidneys?
11th and 12th ribs
the average adult urinary bladder is moderately full with _____________ of urine within it.
500 mL
