Capillary Dynamics Flashcards
1
Q
When is diffusion most rapid?
A
When ions and molecules involved are small
Distance is short
And concentration gradient is large
2
Q
What is filtration?
A
The removal of salutes from a solution flowing across a porous membrane
3
Q
What is filtration driven by?
A
A hydrostatic pressure (Capillary hydrostatic pressure)
(Push of water from a higher concentration to a lower concentration) area
4
Q
How does reabsorption occur?
A
Occurs through osmosis
5
Q
What does it mean a solutions concentration is higher?
A
It means that osmotic pressure is quite great
6
Q
What is the blood colloid osmotic pressure?
A
When capillary walls create pressure due to the suspended blood proteins that are too large to cross cap walls
(Precents osmosis)
