cloaca

The combined urinary and faecal opening in the embryo before the two become separated. The term derives from the Latin cloaca a sewer.

cloaca

the terminal part of the gut system of most vertebrates (except higher mammals) into which the ducts from the kidney and reproductive system open. In these types there is thus only one posterior aperture to the body as compared with two in mammals, the anus and the opening of the urinogenital system. In some vertebrates, such as birds, the cloaca is reversible and forms a penis-like structure in the males during copulation.

cloaca

pl. cloacae [L.]
1. a common passage for fecal, urinary and reproductive discharge in most lower vertebrates.
2. the terminal end of the hindgut before division into rectum, bladder and genital primordia in mammalian embryos.
3. an opening in the involucrum of a necrosed bone.

avian cloaca
in birds the cloaca is divided into three poorly defined compartments: a coprodeum or a continuation of the rectum, a urodeum into which the urogenital ducts open (in the female the left genital duct is the oviduct) and the proctodeum which carries the cloacal bursa and the proctodeal glands.
common cloaca
the urorectal septum fails to develop; defecation and urination share a common cavity. Seen in Manx cat.
