|
renal tubule collects fluid lost from the glomerulus and processes it to form urine
|
|
|
What is the process of tubular reabsorption?
|
It is the process of returning material to the blood from the the renal tubule
|
|
|
What doe the glomerular filtrate contain?
|
Cl-, K+, Ca++, Na+
- organic material (amino acid, glucose, carbs) |
|
|
Where does most of the re-absorbtion occur?
|
At the PCT
|
|
|
What do the cells of the PCT produce to increase efficiency of re-absorbtion?
|
microvilli
|
|
|
What regulate the (some) re-absorbtion at the DCT
|
-ADH for water re-absorbtion
-Aldosterone for Na+ and water re-absorbtion |
|
|
What % of water & Na+ is re-absorbed?
|
65%
|
|
|
What % of K+ and Cl- are re-absorbed?
|
50%
|
|
|
What are the PCT & DCT are mostly used for?
|
re-absorbion & secretion
|
|
|
Where is most secretion done?
|
PCT but significant at DCT
|
|
|
