An organ of the urinary

system whose primary

function is transport of

urine is:

The cone shaped regions

of tissue in the renal

medulla of the kidney

are called:

renal pyramids

The blood supply to the

glomerulus is via the

afferent arterioles

Blood leaves the capillary

cluster of the renal capsule

via the

efferent arteriole

The relatively high pressure

in the glomerulus is due to:

smaller diameter of the efferent arteriole compared to the afferent arteriole

The end product of

kidney function is:

Urine

Sympathetic nerve impulses

will likely _____ glomerular

filtration

decrease

Approximately how much fluid

filters through the glomerulus

in 24 hours?

decrease

Which of the following

substances is present in

glomeruluar filtrate but

not urine in a healthy individual?

Glucose

Which hormone increases

the reabsorption of Na+ in

the distal convoluted tubule

and collecting duct?

Aldosterone

Which of the following

substances is transported

by osmosis through the

renal tubule?

Water

The step in urine formation

where blood is filtered is:

glomerular filtration

The process that acts to

continue sodium reabsorption

from tubular fluid in the loop

of Henle and at the same time

causes the fluid to become

hypotonic to its surroundings is:

countercurrent mechanism

Urea is a by-product of

_________ catabolism

Protein

Which allows greater amounts

of a substance to be excreted

in the urine than was filtered

from the plasma in the glomerulus?

tubular absorption

Urine is conveyed from

the kidney to the bladder

via the _______.

Ureter

The urethra travels through

which structure in males?

Penis

The organ that stores urine

until it is eliminated from

the body is the:

urinary bladder

The smooth muscle covering

the urinary bladder is the ____

detrusor muscle

The part of the nephron

involved in filtration of

the blood plasma is ___.

Glomerulus

Which of the following

structures is under

conscious control?

external urethral sphincter

The four main organs of the urinary

systemare the _______, _______,

_______, and ______________.

The ________ gland superior to

the kidney secretes the hormone

aldosterone which affects the

kidney in retaining sodium (Na+)

and secreting potassium (K+).
