Introduction/pH Flashcards
Water makes up what % of the human body?
50-70% (~60%)
Do male or females have a higher water ratio? Why?
Men because females have more adipose tissue
Two major compartments of body water? What %?
- ICF (40% or 25 L)
2. ECF (20% or 15 L)
What two components make up ECF? What %?
- ISF (80% or 12 L)
2. Plasma (20% or 3 L)
What differentiates ISF and Plasma?
Plasma Proteins
What is the osmolarity of ICF and ECF?
Equal
3 methods for water intake?
- Food
- Water intake
- Metabolic (reactions)
3 methods for water output?
- Feces
- Respiration
- Sweating
Which 2 particles do the body act as a solvent for?
- Electrolytes
2. Nonelectrolytes
What constitutes an electrolyte?
Particles that can dissociate in solution from other particles
AND
exist as an electrically charged ion
What constitutes a nonelectrolyte?
Particles that cannot dissociate in a solution; they are mostly organic
Ways in which solutes can be expressed (3)?
- Moles (mol/L)
- Equivalents (Eq/L)
- Osmoles (Osm/L)
In biological solutions, concentrations of solutes are written how? Are they usually high or low?
millimoles/L, milliequivalents/L, and milliosmoles/L
AND
low
What is osmolarity? How is it expressed?
Concentration of particles in a solution
AND
osmole/L
What 2 things contribute to the osmolarity of a solution?
- Electrolytes
2. Nonelectrolytes
