Q

How Blood Travel through Kidney

A

) Renal Artery -> Segmental Art -> interlobar art -> arcuate art -> interlobular art -> afferent arteriole -> Glomerulus -> efferent arteriole -> Peritubular OR vasa recta -> interlobular VEINS -> arcuate Veins -> interlobar veins -> Renal Veins

16
Q

Char of Proximal Convoluted tubule

A

Simple cuboidal; Microvilli; Cell reabsorbs nutrients and water

17
Q

Loop of Henle

A

Reabsorbs water and Ions; Has Descending Limb and Ascending limb

18
Q

Char of Descending Limb of Loop of Henle

A

(top)Thick; simple cuboidal Thin; simple squamous

19
Q

Ascending

A

Goes from Thin to thick. Thick; simple cuboidal while thin is simple squamous

20
Q

Distal convoluted tubule

A

1) Simple cuboidal 2) Microvilli 3) Water & Sodium reabsorption 4) Aldosterone and ADH act here(water retention)

21
Q

Collection Duct

A

1) Simple cuboidal 2) Merge to form Papillary Duct -> minor Calyx 3) ADH acts here

22
Q

Juxtaglomerular apparatus

A

1) Juxtaglomerular cells 2) Macula densa cells 3) regulates blood Pressure

23
Q

1) Juxtaglomerular cells

A

Smooth muscle of afferent arteriole

24
Q

Macula densa cells of Juxtaglomerular apparatus

A

In the Distal Convoluted Tubule(DCT) 2) Monitor electrolyte concentration and stimulate Juxtaglomerular cells to release RENIN

25
Q

RENIN (hormone)

A

Act to release Aldosterone and ADH(water retention in the Macula densa in the Juxtaglomerular apparatus

26
Q

Ureter

A

Connects Kidneys to Urinary bladder 2) Retroperitoneal 3) 2 Layers

27
Q

Layer so of Ureters

A

1) Mucosa (transitional Tissue) 2) Muscularis ( inner longitudinal. Outer circular Smooth muscle)

28
Q

Urinary Bladder Location

A

Posterior to pubic symphysis and Retroperitoneal

29
Q

Function of Urinary Bladder

A

Holds Urine

30
Q

Urinary Bladder Shape and Layers

A

Triangular shaped(trigone) 2) Mucosa (transitional with rugae) 3) Muscularis with detrusor muscle

31
Q

Detrusor Muscle

A

Smooth muscle in the Bladder; make you pee

32
Q

Urethra Connects

A

Bladder to exterior

33
Q

2 sphincters of the Urethra

A

Internal Urethral; part of detrusor 2) external Urethral (SKELETAL MUS)

34
Q

Female urethra

A

Urinary function and stratified squamous

35
Q

Male Urethra Function

A

Urinary and reproductive

36
Q

Parts of Meal urethra

A

Prostatic; transitional 2) Membranous; pseudostrat and Columnar 3) Spongy pseudo strat & strat squamous
