(klÅÄ`kÉ), in biology, enlarged posterior end of the digestive tract of some animals. The cloaca, from the Latin word for sewer, is a single chamber into which pass solid and liquid waste materials as well as the products of the reproductive organs, the gametes. Cloacas are found in amphibians, reptiles, birds, and lower mammals; higher mammals have a separate rectal outlet, the anus.
It also occurs in birds that have a habit of holding in the stool for long periods of time, like overnight, instead of dropping it as it is comes to cloaca. Any combination of the above reasons can lead to straining, dilating and stretching of the vent, making the bird an ideal candidate for cloacal prolapse. 1  1.he cloaca is the part of the birdâs body which stores urates, feces, urine and egg. The cloacal lips (or vent) are used to control the passage and frequency of droppings and other eliminations.
