CP 5 Flashcards
1
Q
If a solution has the SAME osmolarity it is…?
A
Isosmotic
preferred resting state in intra/extracellular fluid so osmosis does not occur
2
Q
If a solution has a LOWER osmolarity it is…?
A
Hyposmotic
3
Q
If a solution has a higher osmolarity it is…?
A
Hyperosmotic
4
Q
What is tonicity?
A
The effect a solution has on cell volume, dependent on permeability of the solute (not always the same as osmolarity)
5
Q
What is an isotonic solution? How does it affect cells?
A
No change in cell volume (no affect on cell)
6
Q
What is a hypotonic solution? How does it affect cells?
A
- Net gain of water
- Causes swelling and lysis (hemolysis)
7
Q
What is a hypertonic solution? How does it affect cells?
A
- Net loss of water
- Causes cell shrinkage (crenation)
