Special Topic Flashcards
1
Q
What does the height of the box mean?
A
The osmolarity (ECF)
2
Q
What does the width of the box mean?
A
The volume. (ICF)
3
Q
Aldosterone
A
-regulates ECF volume by controlling sodium.
- a lack = sodium loss
-excess = sodium retention
4
Q
vasopressin
A
-regulates extracellular osmolarity; water reabsorption
-lack = increase urine output
-excess = decrease urine output & urine retention
5
Q
If the height increases
A
The cell loses water & shrinks
6
Q
If the height decreases
A
the cell gains water & swells
7
Q
If the cell’s width shrinks,
A
the volume decreases, there is a fluid loss
8
Q
if the cell’s width increases,
A
The volume increases, water gain
9
Q
If the width moves, but the height doesn’t , what does that mean?
A
Isotonic fluid does not affect the cell osmolarity.
