Only one side of paired repro- ductive ducts is shown. The egg moves from the ovary in- to the body cavity, where it comes in contact with cilia. The cilia move the egg toward the heart, where the opening of the oviduct—the ostium— is located. Eggs are taken in by the ostium and propelled through the oviduct by means of the cilia which line the oviduct. A jellylike substance secreted by the oviduct is de- posited on the eggs.
