    Note:
    Total @CT01101@ is the sum of the clearances of each eliminating organ or tissue for a given substance.
  2. in in pulmonary toxicology: Volume or mass of lung cleared divided by time of @E02038@; used qualitatively to describe removal of any inhaled substance which deposits on the lining surface of the lung.
