The atrial cavity in a lancelet serves as a space that facilitates the flow of water through the organism's body. It plays a crucial role in respiration and feeding by allowing water to pass over the gills, where gas exchange occurs and food particles can be filtered out. This cavity helps maintain the lancelet's simple body plan while supporting its basic physiological functions.
