A common passageway for feces, urine and reproduction. At one point in the development of the human embryo, there is a cloaca. It is the far end of a structure called the hindgut. This structure then divides to form a rectum, a bladder, and genitalia. The presence of a cloaca is normal in many adult animals (birds, reptiles, amphibians, some fish, [..]

An expanded, tubular structure that serves as the common opening of the digestive, reproductive and urinary systems in many vertebrates, including birds.

waste passage (pop)

The posterior opening that serves as the only opening for the intestinal, reproductive, and urinary tract of certain animals such as birds, reptiles, and amphibians.

A body opening that serves both for excretion and for the reproductive organs in reptiles, amphibians, and birds, as well as many fish and some invertebrates.

The external opening to expel fecal matter. In birds there is a single opening for intestinal (fecal matter), urinal (urine and urates), and genital tracts. Commissure

The common chamber into which the intestinal, urinary and genital tracts discharge in birds, reptiles, amphibians and many fishes; also a phylogenetically related embryonic structure in mammals.

In amphibians, fish, birds, and reptiles, an opening through which the digestive, urinary, and reproductive tracts exit the body.

common chamber at end of digestive and urogenital systems

The opening in the rear of chickens through which the intestinal, urinary and reproductive tracts empty.

common duct for the passage of feces, urine and reproductive products in birds and reptiles. Also called a vent.

The single excretory cavity in some animals.

The common chamber into which the reproductive and excretory ducts open.

The posterior opening of an animal, such as a Newt, from which they excrete both urine and faeces.

Shared chamber into which gut, urinary and reproductive ducts open; found in birds, reptiles, amphibia, and many fish.

A dilated cavity extended caudally from the hindgut. In Adult Birds, Reptiles, Amphibians, and many Fishes but few Mammals, cloaca is a common chamber into which the digestive, urinary and reproductiv [..]
