Body fluid compartments Flashcards
1
Q
What does ECF consist of
A
Plasma and interstitial fluid
2
Q
How do plasma and interstitial fluid exchange substances
A
Through highly permeable capillary membranes however most proteins too big to permeate so maintained in higher conc in plasma than in interstitial spaces
3
Q
How is ICF fluid separated from ECF
A
By membranes highly permeable to water but not permeable to most electrolytes
4
Q
What are spingolipids
A
They contain amino alcohols and have hydrophilic-hydrophobic characters
5
Q
What is the difference between primary and secondary active transport
A
Primary uses the energy source directly whereas secondary uses it indirectly
6
Q
What influences rate of transport
A
- Concentration
- Electrical potential
- Pressure
7
Q
What is the permeability co-efficient of a solute
A
It is the rate of movement calculated in cm/sec
