the glomerular capillary bed is __-pressure
incorrect

name the 3 processes that urine results from
incorrect
4.
during tubular reabosorption
incorrect
5.
what does the JGA consist of
incorrect
6.
b.c of this the two major resulting factors are
incorrect
7.
explain the performance functions of the kidneys
incorrect
8.
the glomerulus produces the ___ & the peritubular capillaries __ most of that filtrate
incorrect
9.
the tissue in the loop of Henle is
incorrect
10.
what type of pressure is the peritubular capillaries
incorrect
11.
tubular secretion
incorrect
12.
name the substances that move either fm the blood of the peritubular capillaries through the tubular cells or from the tubular cells into the filtrate to be disposed of in the urine
incorrect
13.
trigone
incorrect
14.
what does this cause?
incorrect
15.
what are they?
incorrect
16.
vessels leading to & from the glomerulus, the 1st capillary bed are both __
incorrect
17.
what is filtration
incorrect
18.
voiding is also known as
incorrect
19.
what does the urinary system consist of?
incorrect
20.
name the substaces that are almost entirely reabsorbed from teh filtrate
A.
micturition; urine empties from the bladder
B.
hydrogen, potassium ions & creatinine
C.
low-pressure
D.
arterioles
E.
a passive process in which a portion of the blood passes from the blomerular bed into the glomerular capsule; filtrate enters the proximal convoluted tubule where tubular reabsorption & secretionb begin
F.
filtrate, reclaim
G.
(1) bed is fed & drained by arterioles (arterioles are high-resistance vessels) (2) the afferent feeder arteriole is larger in diameter than the efferent arteriole draning the bed
H.
the reverse process of tubular reabsorption; important for the disposal of substances not already in the filtrate (drug metabolites) controlling device for blood pH
I.
(1) it is a urine conduit to the body exterior (2) provides a passageway for the ejaculation of semen
J.
water, glucose & amino acids
K.
(1) act as a blood "filter" (2) a blood "processor"; allows toxins, metabolic wastes & excess ions to leave the body in the urine while simultaneously retaing needed substances & returning them to the blood
L.
(1) juxtaglomerular (JG) cells (2) pressure sensors in the walls of the arterioles near the glomerulus (3) macula densa, a specialized group of columnar cells in the distal convoluted tubule abuting the JG cells
M.
triangular region of the bladder which is delineated by three openings (2 ureteral & 1 urethral orifice)
N.
paired kidneys & ureters & the urinary bladder & urethra
O.
filtration, reabsorption & secretion
P.
the proximal convoluted tubule, loop of Henle (descending & ascending limbs) & the distal convoluted tubule
Q.
the filtrate components move through the tubule cells & return to the blood in the peritubular capillaries
R.
high
S.
simple squamous epithelium
T.
cery prous capillaries adapted for absorption rather than filteration & redily take up the solutes & water reabsorbed from the filtrate by the tubule cells

21.
what is another name for the glomerulus-capsule complex?
incorrect
22.

incorrect
27.
when the kidneys are less securely anchored to the body wall due to reduced or rapid weight loss (very thin individuals); may cause kidneys to drop to a lower position
incorrect
28.
present in each kidney; the indented medial region where the renal arteries enter
incorrect
29.
receives urine via the ureters & discharges it via the urethra, stores it temporarily
incorrect

anterior to the vaginal opeing, the external opening
