Filtration Flashcards
1
Q
Where does filtration occur
A
At the renal corpuscle
2
Q
How does blood pressure help with Filtration?
A
- forces water and dissolved solutes out of glomerular capillaries into capsular space
-produces protein-free solution(filtrate) similar to blood plasma
3
Q
What are the 3 functions of the renal tubule?
A
- Reabsorb useful organic nutrients that enter filtrate
- Reabsorb more than 90 percent of water in filtrate
- Secrete waste products that failed to enter renal corpuscke through filtration at glomerulus
4
Q
Proximal convoluted tubule function
A
Reabsorption of water, ions, and all organic nutrients
5
Q
Distal convoluted tubule function
A
Secretion of ions, acids, drugs and toxins
Variable reabsorbptoon of water, sodium ions, calcium ions(under hormonal control)
6
Q
Renal corpiscle function
A
Production of filtrate
7
Q
This makes up 85 percent of all nephrons
A
Cortical nephrons
8
Q
Where are the cortical nephrons located?
A
Mostly within superficial cortex of kidney
9
Q
How long is the nephron loop?
A
It is relatively short
10
Q
The efferent atteriole in the cortical nephron delivers
A
A network of peritubular capillaries
