Histology Urinary System

Front 1

Filtrate includes...

Back 1

water,nitrogenous wastes, amino acids, glucose, ions

Front 2

* Functions of mesangial cells:

Back 2

* Structural support to the glomerulus
* Phagocytosis of protein components

Secretion of substances needed for defense and repair in glomerulus

Front 3

* Forms bulk of cortex
* Lined with simple cuboidal epithelium
* Cells have microvilli (brush border) therefore luminal border is irregular
* Reabsorbs 60-65% of water, 85% of NaCl, and 99% of glucose and amino acids present in filtrate
* Reabsorbed to peritubular capilaries
* PCT is continuous with the descending limb of the loop of Henle

Back 3

proximal convoluted tubule

Front 4

* Located largely in the medulla
* Thin descending portion is lined by simple squamous epithelium
* Thick ascending portion is lined by simple cuboidal epithelium

Back 4

Loop of Henle

Front 5

* cuboidal epithelial cells are smaller and lumen is wider and more distinct (no brush border) than PCT
* is shorter than PCT therefore find fewer DCT in section
* a few short microvilli might be present
*

Back 5

distal convoluted tubules

Front 6

* Kidneys also have endocrine function:

Back 6

secrete

* erythropoietinrenin

Front 7

organs involved in this system

Back 7

2 kidneys, 2 ureters, urinary bladder and urethra

Front 8

blood vessels involved in blood supply to kidney

Back 8

renal artery, afferent & efferent arterioles, peritubular capillaries & vasa recta, renal vein

Front 9

layers of the bowman's capsule

Back 9

visceral and pareital layers

Front 10

what type of cells are located between the capillaries of the bowman's capsule

Back 10

mesengial cells

Front 11

Back 11

Renal Corpuscle:

-Bowman's capsule

-glomerulus

*distal convoluted tubules

*macula densa

*afferent arteriole

*

Front 12

function of proximal convoluted tubule

Back 12

* Reabsorbs 60-65% of water, 85% of NaCl, and 99% of glucose and amino acids present in filtrate

Front 15

what is the outer layer of urinary bladder

Back 15

serosa

Front 16

difference between male and female urethra

Back 16

* In female, there is no stratified columnar epith. or pseudostratified
* portion
