|
Ureter

|
|
Nephron is where?

|
|
How does filtrate flow through the nephron?
|
(glomerulus) then STARTS AT BOWMANS capsule...-->PCT-->Loop of Henle-->DCT-->Collecting Duct-->Renal Pelvis-->(then Ureter, Bladder, Urethra)
|
|
|
What are the things that surround the nephron?
|
Peritubular Capillaries
|
|
|
Filtration
|
OUT of the glomular capillaries INTO the nephron
|
|

DCT
|
|
|
Secretion
|
OUT of peritubular capillaries INTO the nephron
|
|
|
Excretion
|
Collecting duct to the renal pelvis then the urinary tract (ureter, bladder, urethra)
**Only subs. that were not reabsorbed or were secreted into the tubule! |
|
|
Sweat Glands
