What separates plasma from interstitial fluid?
Highly permeable
capillary membranes
View source
What is the main difference between plasma and interstitial fluid?
Higher concentration of
protein
in plasma
View source
Why do only small amounts of proteins leak into interstitial spaces?
Capillaries
have low permeability to proteins
View source
What effect increases cation concentration in plasma?
Donnan effect
View source
How much greater is the cation concentration in plasma compared to interstitial fluid?
About 2
percent
greater
View source
Why do plasma proteins hold extra cations in plasma?
They have a
net negative charge
View source
Where is the concentration of anions slightly higher?
In the
interstitial fluid
View source
What ions are found in large amounts in extracellular fluid?
Sodium
and
chloride
ions
View source
What regulates the composition of extracellular fluid?
The
kidneys
View source
Why is the regulation of extracellular fluid important?
To maintain proper
electrolyte
and
nutrient
concentration
View source
What separates intracellular fluid from extracellular fluid?
A
cell membrane
View source
What is the permeability of the cell membrane to water?

View source
What ions are found in large amounts in intracellular fluid?
Potassium
and
phosphate
ions
View source
