Problem set: water and solute movement across membranes

Water and solute movement across membranes (Ch.5)

Differentiate between the terms osmole, osmolarity, osmolality and tonicity. List typical values and ranges for plasma osmolarity and osmolality

Use measurements with molecular weight, grams, mole, and osmole.

Define and convert between units used to describe concentration of a solution: percent, Eq/l, grams/l, molarity, osmolarity. (see text pp.35-36)

List the body water compartments of the body and describe their separation.

Differentiate between hyper-, hypo-, and isosmotic solutions and predict osmosis between solutions of these types.

List the normal value and range for plasma and interstitial Na+, K+, H+ (pH), HCO3-, Cl-, Ca2+ and glucose.

List the normal value and range for intracellular Na+, K+, H+ (pH), HCO3-, Cl-, Ca2+.

Differentiate between hyper-, hypo-, and isotonic solutions and predict solute movement and osmosis in and out of cells for each.

Describe the action of water and solutes in various solutions using penetrating (glucose, urea) and non-penetrating (NaCl) solutes (including Table 5-9 IV solutions).

6.

If a 2 liter solution with 10 osmoles of sucrose  (A) is separated from a 5 liter solution with 20 osmoles of sucrose (B) by a membrane impermeable to sucrose and permeable to water, in which direction will movement of water occur?

a.

from solution A to solution B

b.

from solution B to solution A
