Water Balance Flashcards
1
Q
Factors that disrupt water balance
A
Illness
Too much salt
Sweating
Exhalation
2
Q
Why do water levels have to stay constant
A
order to control the amount of water and ions diffusing in and out of cells.
3
Q
Hypertonic
A
A hypertonic solution has a lower water concentration and a higher ion concentration than cells.
If the blood becomes hypertonic, cells lose water by osmosis and shrink.
4
Q
Hypotonic
A
A hypotonic solution has a higher water concentration and a lower ion concentration than cells.
If the blood becomes hypotonic, cells gain water by osmosis and burst.
5
Q
Isotonic
A
An isotonic solution has the same water and ion concentration as cells.
Homeostasis works to regulate the blood’s water and ion concentrations so that it remains isotonic.
