Cloacal aperture can be defined as the posterior opening on the body surface of the cloaca in vertebrates such as in birds, reptiles, fish, and amphibians.
Tortoises defecate through their cloaca, which functions as their anus.
all of them except for mammals(amphibians,birds,fishes,reptiles)PS. anyone can edit this question.
The function of the cloaca is: urinary, intestinal, and genitalia.All of the urine/sperm is held here, then to the bladder.A frog's cloaca allows a frog to deliver eggs and sperm to get them ready for fertilization. The cloaca also allows the frog to pass waste products out of its system.To expell wast and spermerects.The function of a frog's cloaca opening is how it excretes wastes. both liquid and nonliquid exit the frog from this is opening.all of the urine and sperms/eggs go through here and to the bladderThe cloaca receives urine, and digestive wastes, and also it holds reproductive cells (eggs or SPERM).-KATTHHHAYYY(;hehe monkey butts!Cloaca is an aperture that is the outlet of digestive, excrertory, and reproductive systems.
Digestive, urinary and reproduction
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.
The cloaca is the chicken's equivalent of a rectum and genitals. The anus of a hen is at one end of the cloaca, at the posterior end of the animal. It functions in reproduction, as the site of mating and egg-laying. It also has an intestinal function and is part of the urinary tract, as both urine and faeces are excreted through it.
The reproductive system of a monotreme (such as the platypus or echidna) empties into a cloaca, which is a single opening for excretory, digestive, and reproductive functions. The cloaca is found in both male and female monotremes, serving as the common exit point for waste and reproductive fluids.
No. Mammals do not have cloaca's.
The role of diaphragm is to vary the amount of light passing through the aperture.
To produce sex cells and hormones specific to the gender.. Then this is released through the cloaca. Hope this helps :)
