Net movements of water, Na, Cl, K, Ca, Mg and Pi were measured in the stripped and everted intestine of the carp. A high concentrative absorbtion of Pi was observed, whereas Na and Cl were absorbed almost isotonically. The rate of Pi absorption was greater in the middle part than in the anterior or posterior part of the intestine.
