kidney are located 
 
behind parietal peritoneum (retroperitoneal) against the deep muscles of back on either side...
14
overall function of kidney

15
specific function of the kidneys are to

16
renal arteries arise from
 
abdominal aorta
17
renal arteries carry from ____% to _____% of cardiac output at rest by several ____arteries
 
15 30interlobar
18
interlobar arteries pass between 
 
renal pyramids
19
when interlobar arteries reach the junction between the____and ____, they branch to form a...
 
medullacortexincomplete arteries 
20
final branches of interlobular arteries are 
 
afferent arterioles
21
afferent arterioles lead to
 
nephrons
22
venous blood is returned through 
 
a series of veins that generally correspond to arterial pathways and that join the renal vein,...
23
efferent arteriole is _______than afferent arteriole
 
smaller than
24
________is important in regulating the secretion of renin
 
juxtaglomerular apparatus
25
functional unit of kidney
 
nephron
26
each nephron consists of ______and _____
 
renal corpuscle renal tubule
27
renal corpuscle is ________unit of nephron
 
filtering
28
renal corpuscle consists of 
 
cluster of capillaries (gloemrulus)surrounding glomerular capsule
29
cluster of capillaries in renal corpuscle 
 
glomerulus 
30
afferent arterioles give rise to 
 
glomerulus 
31
glomerulus leads to 
 
efferent arterioles
32
first step in urine formation
 
filtration of renal corpuscle
33
glomerular capsule is an ______at the end of renal tubule and receives _____
 
expansionglomerular filtrate
34
renal tubule consists of 
 
two layers of squamous epithelial cells1. visceral layer2. outer parietal layer
35
visceral layer of renal tubule
 
covers glomerulus 
36
outer parietal layer of renal tubule
 
continuous with visceral layer and with wall of renal tubule 
37
renal tubule leads away from 
 
glomerular capsule and becomes very coiled, forming proximal convoluted tubule. 
38
renal tubule becomes
 
proximal convoluted tubule 
39
following convoluted tubule is 
 
nephron loop (loop of Henle)
40
after nephron loop of henle is 
 
distal convoluted tubule and ascending limb of tubule
41
distal convoluted tubule is ____and ______than proximal tubule and converges with other tubules...
 
shorter straighter collecting duct
42
____is formed by tightly packed epithelial cells in the region where tubule passes between...
 
macula densa 
43
juxtaglomerular cells
 
large vascular smooth muscle cells 
44
juxtaglomerular cells form _____along the cells of macula densa
 
juxtaglomerular apparatus 
45
juxtaglomerular apparatus is important in 
 
regulation of renin secretion 
46
Glomerulonephritis
 
immune reaction triggered by antigens of beta hemolytic streptococcus 
47
body reacts to beta hemolytic streptococcus antigens by 
 
forming antibodies that join with the antigens to form insoluble complex that block the glomerulus.white...
48
most patients of glomerulonephritis
 
regain normal function some renal function fails and dialysis is required 
49
afferent arteriole is ______than efferent arteriole which causes increased ________to blood...
 
larger resistance
50
increased resistance to blood flow in the efferent arteriole causes blood to 
 
back up into the glomerulus 
51
back up of blood in glomerulus results in
 
relatively higher pressure in the glomerulus capillaries than in nonglomerular capillaries
