1

functions of kidney

regulate water and minerals

hormonal regulation

maintain blood volume and pressure via H2O secretion/reabsorption

2

structures of urinary system

kidneys

ureters

urinary bladder

urethra

3

neprhon

functional unit of kidney

smallest unit that can perfom basic kidney function

1 million per kidney

4

2 components of nephrons

vascular

tubular

5

2 regions of nephron

medulla

cortex

6

renal corpuscle of neprhon

initial filtering component-form filtrate

7

tubule component of kidney

extends from corpuscle-adds or removes particles to filtrate

8

4 parts of renal corpuscle

afferent arteriole

glomerulus-capillary bed

efferent arteriole

bowman's capsule- "cup"

9

basic renal process

amount excreted=amount filtered+amount secreted-amount reabsorbed

10

filtration of plasma from glomerular capillaries yields what?

filtrate-not urine et

same as plasma but no proteins present

11

glomerular capillary endothelium

single layer of endothelial cells with large fenestrae

12

basement membrane

collagen framework

13

podocytes

encircle the gomerulus

slit diaphragm between foot processes

14

4 forces involved in glomerular filtration

capillary hydrostatic pressure

hydrostatic pressure in bowmans space

osmotic force of protein capillary

osmotic force of boman's space
