.... The ADF is greatest for the lining of the atrium and for the skin covering the segmental muscles. Calculation of the diffusing capacities for O 2 revealed that the lining of the atrium makes up nearly 83 % of the entire diffusing capacity (8.86×10 −3 μl min −1 mg −1 kPa −1 ) while the skin over...
