An apparatus for exchanging gases in a liquid is provided. Preferably, the apparatus comprises a housing, a first inlet, a gas exchange medium, a separator, a first outlet, and a second inlet and outlet. The apparatus may further comprise a circumferential collection gap that collects liquid from the gas exchange medium and directs it toward the first outlet. Also, the apparatus may further comprise a compliant chamber positioned near the first inlet. The compliant chamber reduces the overall impedance of the apparatus. The apparatus is particularly well-suited for use as an implantable, artificial lung. In this embodiment, the liquid comprises blood and the apparatus exchanges supplied oxygen for waste carbon dioxide.
