In zoological anatomy, a cloaca is the posterior opening that serves as the only such opening for the intestinal, reproductive, and urinary tracts of certain animal species. The word comes from Latin, and means sewer. All birds, reptiles, and amphibians possess this orifice, from which they excrete both urine and feces, unlike placental mammals, which possess two separate orifices for evacuation.
A cloaca is the posterior opening in birds, reptiles, fish and monotremes (egg-laying mammals) which is the single opening for the reproductive, intestinal and urinal tracts. These animals pass their urine, faeces and eggs as well as live young through this opening. The word actually means sewer.
In a frog, the oviduct is the tube that allows eggs to come out of the cloaca. The cloaca is a common opening for the reproductive, digestive, and urinary systems in amphibians, and the oviduct is responsible for transporting eggs from the ovary to the external environment through the cloaca.
Waste empties into the cloaca, which is a multi-functional opening in frogs used for excretion, reproduction, and digestion. From the cloaca, waste is expelled out of the frog's body through the vent.
A pig does not have a cloaca because they have both reproductive organs and an anus. Only animals with 1 opening have a cloaca.
It is called a cloaca, pronounced klo-a-ka
all of them except for mammals(amphibians,birds,fishes,reptiles)PS. anyone can edit this question.
No. Mammals do not have cloaca's.
Cloaca.
No ,male dogs do not possess cloaca but placental mammals have cloaca in their embryonic stage.
A cloaca is an opening in the posterior of an animal. It is used to eliminate body waste such as urine. An inverted cloaca means that the cloaca is turned inside and is not opening properly.
Yes. A cloaca is present in marsupials and monotremes, as well as in birds, amhibians and reptiles. Placental mammals do not have a cloaca.
Cloaca is pronounced as kloh-AY-kuh.
Cloaca - film - was created in 2003.
Monotremes, the echidna and platypus, have a cloaca. Monotreme means one hole, and is a reference to the cloaca.
Cloaca Maxima II was created in 1998.
Monotremes, which include just the echidna and platypus, have a cloaca.
No, humans do not have a cloaca. A cloaca is a single multipurpose opening for the urinary, reproductive, and digestive systems found in some animals like birds and reptiles. Humans have separate openings for these systems.
