| 1 |
hydrophilic
|
A molecule that is polar and attracts water and easily dissolves in water.
|
|
| 2 |
hydrophobic
|
molecule that don't dissolve in water because they are nonpolar (lipids)
|
|
| 3 |
Phospholipid
|
part of plasma membrane with hydrophilic heads and hydrophobic tails facing inward, sandwich...
|
|
| 4 |
ICF2
|
2/3 of our fulids in ICF. chemical reactions for metabolism happen here, overall negative charge....
|
|
| 5 |
ECF
|
all body fluid outside of the cells. 1/3 of our fluid. Major molecules: **NA+**, NACO3-, Cl-
|
|
| 6 |
interstital fluid
|
Fluid outside of the 80% of our ECF is interstitial.
|
|
| 7 |
Hydrostatic pressure
|
forces fluid out of a space due to pressure.
|
|
| 8 |
osmotic pressure
|
fluid flows into a space via osmosis (presence of solutes)
|
|
| 9 |
osmosis
|
movement of water from an area of lower solute concentration to an area of higher concentration
|
|
| 10 |
Osmolarity
|
unit of concentration, measured in Osmoles per Liter (think moles from chemistry)
|
|
| 11 |
water balance
|
daily water intake must equal output. water gain vs. water loss.
|
|
| 12 |
water gain
|
in hypothalmus monitor ECF osmolarity and when it gets too high, it stimulates the cortex to...
|
|
| 13 |
water loss
|
negative feedback loop between hypothalmus and kidneys. kidneys reabsorb water if too much...
|
|
| 14 |
sensible/insensible water loss
|
sensible - noticeable, sweat, urine, feces, etc. insensible - light perspiration, and respiration.
