Why does the hematocrit rise when a person isdehydrated?
| A. | An increase in plasma electrolyte concentration is recorded onthe hematocrit. |
| B. | Edema occurs, meaning water moves from the circulation into theinterstitial fluid. |
| C. | Sweat is mainly water and when the water content of blooddecreases the hematocrit is increased. |
| D. | Sweat is mainly water and when the water content of blooddecreases the hematocrit is decreased. |
2.  What values are correct for cation concentrationsin plasma?
| A. | Protein = 7% |
| B. | Cl- = 140 mM |
| C. | Ca2+ 1 µM |
| D. | Na+ 139 mM |
3. Albumins:
| | A. Account for ~30% of the plasma proteins. They function asimmunoglobulins which attack foreign proteins, and also transporthormones. |
| | B. Account for ~70% of the plasma proteins. They function asimmunoglobulins which attack foreign proteins, and also transportapolipoproteins. |
| | C. Account for ~70% of the plasma proteins and are majorcontributors of plasma osmolarity. |
| | D. Are the most abundant plasma protein and are the majorcontributor of the osmotic pressure of formed elements. |
