Since the blood does not return to the heart after flowing
through the gills, pressure is not regenerated within the system before it
flows to the systemic circulation (the rest of the body). A single circulation
would experience a loss of pressure after flowing through the gas change organs
(gills of a fish) due to the high cross-sectional area presented by the

it had an open circulatory system. However, the most common would be the fish
