29
What is Diffusion?
Movement of molecules through a semipermeable membrane from a higher concentration area to a lower concentration.
30
What is Active Transport?
The process in which molecules move against the concentration gradient. External energy is needed for this process.
31
What is Omosis?

32
What is osmotic pressure?
The pressure needed to prevent osmosis?
33
What is hydrostatic pressure?
The force of fluid in a compartment pushing against a cell membrane or vessel wall.
34
What is oncotic pressure?
The osmotic pressure caused by plasma colloids in solution.
35
What major colloids contribute to oncotic pressure?
Proteins such as albumin.
36
What is a normal sodium level?

37
What is a normal Potassium level?
3.5-5 “I only really want to buy 3.5-5 bananas at time”
38
What is a normal Calcium level?
9-10.5mg/dL “Call 911!” - this worked better with the range being 9-11 but these are Hajari’s numbers
39
What is a normal Phosphorus level?
3-4.5mg/dL
40
What is a normal Chloride level?
95-105mEq/L “95-105 degrees is perfect swimming pool (chlorine sounds like chloride) weather”
41
What is a normal Magnesium level?
1.3-2.1mEq/L “You should stop drinking after 1.3-2.1 beers” because hypomagnesemia can occur with excessive drinking

46
What is fluid spacing?
The term used to describe the distribution of body water.
47
What does first spacing mean?
Normal distribution of fluid in ICF and ECF compartments.
48
What does second spacing mean?
Refers to an abnormal accumulation of interstitial fluid.
