What is ICF and ECF?
|
intracellular fluid- in the cell
extracellular fluid- outside the cell Water moves btw across the cell membrane |
|
___= Passive transport system, where water moves across the cell membrane from LOW to HIGH solute concentration
EX: swimming in a pool/ocean, and your fingers pruning -curing meat - frogs dont drink water, they absorb it thru their skin |
osmosis
|
|
___= passive transport where substances move from area of HIGH to LOW solute concentrations
EX: perfume spreading throughout the room -alcohol crossing the BBB -gases - dye in water spreading |
diffusion
|

What is normal physiological saline?
Is it isotonic, hypertonic, hypotonic? |
.9% NaCl
isotonic- same pressure |
|
___= solution has lower concentration of the solute, lower pressure than the cell
-to create, you dilute the water ___- when the cell swells in this solution as water enters the cell, going from area of low solute concentration to higher solute concentration |
hypotonic
hemolysis |
|
___= solution has higher pressure, higher solute concentration in the ECF than the ICF
- to create, you add salt ___= occurs in this solution, causes the cell the shrink as water leaves the ( low to high solute concentration) |
hypertonic
crenation |
|
___= how water moves in and out of the cell
|
aquaporins
|
|
___= made of lipid bi-layer of polar heads and non-pokar tails, transmembrane proteins, and is selectively permeable to water
- transport is either passive or active |
cell membrane
|
|
___= solution has the same osmotic pressure as the cell, .9% NaCl
-Normal physiological saline |
isotonic
|
|
___= polymer used in experiment that has a large number of glucose
___= monosaccharide, simple sugar ( source of energy for the cell) ___= indicator of starch (deep blue/dark purple when in the present of starch) ___= permeable to glucose, not starch Think of experiment |
starch
glucose iodine dialysis tubing |
|
___= the constituent of a solution that is dissolved in the solvent
___= the constituent of a solution that dissolves the solute ___= The ratio of the mass or volume of a solute to the mass or volume of the solvent |
solute
solution concentration |
