an acid-base imbalance characterized by an increase in H+ concentration (decreased blood pH).

a low arterial pH due to reduced bicarbonate concentration

a low arterial pH due to increased PCO₂

psysiologic pump that moves fluid from an area of lower concentration to an area of higher concentration; requires adenosine triphosphate (ATP) for energy

an acid-base imbalance characterized by a reduction in H+ concentration (increased blood pH).

a high arterial pH with increased bicarbonate concentration

a high arterial pH due to reduced PCO₂

the process by which solutes move from an area of higher concentration to an area of lower concentration; does not require expenditure of energy

the pressure created by the weight of fluid against the wall that contains it.  in the body, hydrostatic pressure in blood vessels results from the weight of fluid itself and the force resulting from cardiac contraction.

the process by which fluid moves across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration; the process continues until the solute concentrations are equal on both sides of the membrane
