Clams suck in water through an inhaling tube or siphon and expell the water through an exhaling siphon. The water passes over the clam's gill which absorbs oxygen and traps small food particles suspended in the water. The water is moved through the clam by the movement of many tiny hairs or cilia that cover the gill and beat in unison to create a current through the siphons.
