as venous blood is drained from the kidney, which path does it follow?

cortical radiate veins, arcuate veins, interlobar veins, renal vein

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
