Tolerance can be described in two ways: (1) Chronic tolerance is observed as a decrease in the magnitude of an effect of alcohol with repeated exposures; and (2) acute tolerance is observed within the course of the elimination of a single exposure and is characterized by a reduced alcohol effect on the descending limb of the breath alcohol concentration curve (BAC) when compared to the ascending limb.

The terms 'descending limb' of the filament (also descending portion of the filament, i.e., that part of the filament connected to the gill base) and 'ascending limb" (the other part of the filament dorsally unattached or fused with foot or mantle) will be circumvented as far as possible because of developmental and functional connotations.
