A research on the morphometry of the skin of flying membranes in bats Nyctalus noctula and
Eptesicus serotinus (Chiroptera, Vespertilionidae) is carried out, that gives an opportunity to
estimate the aero-hematic barrier between atmospheric air and blood in the capillary tubes
of membranes and to compare it with that in lungs. The obtained morphometric results are
analyzed by allometric analysis. It is established that the value of the aero-hematic barrier of
a bat membrane satisfies the conditions for realizing the gas diffusion, that, in view of a high
degree of the vascularization of the membrane skin, gives the basis for arguing the possible
participation of the skin of membranes in gas exchange.
