Q

DCT

A 
Excrete H2O
Reg. blood from renal cap. 
Histo.
-simp. Cubo. 
-decre. eosin b/c decre. mitoch./BB
18
Q

Collecting duct

A

W/ in cortex and medulla

-ie medullary rays

19
Q

Duct of berlin

A

Medullary duct
In the area of cabrosa
Lrg duct

20
Q

BP reg. By

A

Elevate arteriole P by incre. eff. P

Decre. arteriole P by decre. Aff. P

21
Q

Inctre. Afferent arteriole P

A

Incre. Eff. P=incre. Cap.=incre. GFR
-change iconic conc. and decre. Na/Cl recovery
Macula densa detects an incre. Na/Cl
-release vasoactive to constrict aff. arteriole
-decre. GFR
-decre. Na/Cl

22
Q

Decre. Aff. arteriole P

A 
\+ juxtaglom. cells =modified sm. Muscle 
-release renin (asparty protease) cleaves angiotensinogen form angiotensin I
Lung cap. ACE convert I-->amigo. II
Incre. BP stop renin release 
-temp not chronic
23
Q

Anigo.II

A

Vasoconstrict.= incre. BP
+ adrenal glands release aldosterone
-+ Na/H2O absorb.
-incre. Vol. /incre. P by sm. Muscle BV

24
Q

Urinary exit

A

Urine collected= area cribrosa
Ureters
Bladder
Urethra

25
Q

Urine collection

A 
From tubules= area cabrosa
Collecting tubules join=duct
Lrg. Duct enter renal papilla
Empty-->minor calyx 
-lined w/ urothelium 
-pore w/ lrg collecting duct minot calyx 
  :pore=ducts of Berlin
26
Q

Ureters

A 
Muscle tubules lined with urothelium 
Urine drains from urothelium 
Info. 
-2
-exit renal pelvis (@hilum)
-enters bladder @oblique angle 
  :post surface 
  : Adv. Not urine back flow liq. Press on ureters 
  :orientation/seal tubes 
-wall
  :urothelium 
  :loose CT
  :muscularis (sm. Muscle)
    *inner longitudinal 
    *middle circular 
    *outer longitudinal/distal end 
  :adventitia
27
Q

Bladder

A 
Muscle sac-like organ lined w/ urothelium 
Store urine in pelvis 
2 uretic orifices w/ 1 internal urethric orifices 
-posterior 
Wall
-urothelium 
-loose CT
-dense irreg. CT
-muscularis 
  :3 sm. Muscle layers 
  :irreg. Arrange 
-seroa/adventitia
28
Q

Urethra

A 
Male
-terminal duct for urinary/reproductive 
-3 set. 
  :prostatic (bladder neck through prostate) 
  :memb.(to penis bulb)
  :spongy(penile)
    *glands in wall 
-epith.
  :urothelium(prostatic) 
  :psedostr. (memb.)
  :SSE(spongy)
Female 
-shorter than male 
-urothelium=SSE
29
Q

Urothelium

A 
Ie: Transitional epith. 
Only in urinary tract 
Stretches=cells move pass each other during destention 
-few layers 
-umbrella cellmappear smaller/flatter
