Title: Structure and Function of the Calcium Cells of the Freshwater Pulmonate Snail Lymnaea Stagnalis
Abstract: The morphology and function of the calcium cells of Lymnaea stagnalis were studied. These cells contain concretions consisting of an organic matrix in which inorganic material, mainly CaCO 3 , is deposited. The organic matrix consists of protein, carbohydrate and lipid, synthesized by the Golgi apparatus. It appeared that deposition of CaCO 3 is an active process; CaCO 3 is released from the concretions into the haemolymph via pores in the plasma membrane of the calcium cells. Experiments on snails exposed to water equilibrated with 10% CO 2 in air strongly suggest that calcium cells function in pH homeostasis.
