Nephrons

Question 1

each nephron consists of 2 main structures

Answer 1

renal corpuscle

renal tubule

Question 2

each renal corpuscle consists of (2)

Answer 2

1) glomerulus

2) glomerulus capsule or brownmans capsule

Question 3

glomerulus

Answer 3

knot of capillaries
cup shaped hollow structure
completly surrounds the glomerulus
eg a worn baseball glove

Question 4

glomerular capsule or brownmans capsule

Answer 4

os a cup like sack at the beginning of the tubular component of a nephron
performs the first step in filtration of blood to form urine

Question 5

podocytes

Answer 5

long branching processes called foot processes that intervine with one another and cling to its glomerulus

Question 6

define renal tubule (5)

Answer 6

makes up the rest of the nephron 
3 cm long 
extends from glomerous capsul 
coils and twists 
forming a haipin loop
enters a collecting duct

Question 7

regions of the tubule names in order from gloerular capsule

Answer 7

proximal convoluter capsule (pct)
nephron loop (loop of henle)
distal convoluted tubule (dct)

Question 8

most nephrons are called and why

Answer 8

cortical nephrons - because they are located almost entirely within the cortex

Question 9

collecting ducts are

Answer 9

receives urine from many nephrons that run downwards theough the medullary pyramids

gives them a stripped appearance

Question 10

collecting ducts deliver

Answer 10

final urine into the calyces and renal pevis

Question 11

afferent arteriole are called and it arise from

Answer 11

feeder vessel

cortical radiate artery

Question 12

efferent arteriole receives blood

Answer 12

that passes thru the glomerulus
