Digestive system
The digestive tract, which consists of two contiguous organs: the esophagus and the stomach. The anterior end of the stomach is J-shaped and saclike, and tapers into the posterior part of the stomach known as the pyloric stomach, which bends anteriorly. The stomach terminates at a constriction called the pylorus, which leads to the short duodenum and then to the larger spiral valve intestine, which is highly coiled and twisted internally. The function of the spiral valve intestine is to increase the surface area for digestion and absorption of food, while also conserving space in the body cavity for the large liver and for the development of embryos. The spiral valve, in turn, leads to the rectum and the anus, which opens into the cloaca, a cavity where the digestive, urinary, and genital glands open to the outside.
