How do ducks mate? Both the male and female have an opening called a cloaca. The cloaca is an excretory and sexual opening. During mating, the male and female press their cloacas together (The cloaca is located underneath, near the tail feathers. See picture below.); this is how sperm is passed to the female. They do not have lengthy love making periods, but fast 1 to 3 second copulations that can happen hundreds of times a day. With birds, it’s generally not about quality, it’s about quantity. The male's sperm travels up the oviduct and to the female's eggs.

How on earth do chickens have babies!!!!!? The eggs are fertilised internally, before they have a shell. Like most birds, chickens do not have a penis - they mate simply by pressing their cloacas together in what is known as a 'cloacal kiss'. (The cloaca is the single opening birds use to excrete, mate and lay eggs, in case you didn't know).

Cloaca However, the tenrecs and golden moles, small placental mammals native to Africa, as well as some shrews retain a cloaca as adults. Being placental animals, humans only have an embryonic cloaca, which is split up into separate tracts during the development of the urinary and reproductive organs.

Birth Control Sponge What is the sponge? The birth control sponge (aka the contraceptive sponge or “the sponge” for short), is a small, round sponge made from soft, squishy plastic. You put it deep inside your vagina before sex. The sponge covers your cervix and contains spermicide to help prevent pregnancy. Each sponge has a fabric loop attached to it to make it easier to take out. The only brand of sponge sold in the U.S. is the Today Sponge. How does the sponge work? The sponge prevents pregnancy two ways: It fits snugly against your cervix, blocking the entrance to your uterus so sperm can’t get to your egg. The sponge also contains spermicide, which slows sperm down so it can’t reach your egg. The sponge can be used by itself, or with condoms.

Frog Dissection The urinary system consists of the frog s kidneys, ureters, bladder, and cloaca. The kidneys are organs that excrete urine. Connected to each kidney is a ureter, a tube through which urine passes into the urinary bladder, a sac that stores urine until it passes out of the body through the cloaca.The organs of the male reproductive system are the testes, sperm ducts, and cloaca.onnected to each kidney is a ureter, a tube through which urine passes into the urinary bladder, a sac that stores urine until it passes out of the body through the cloaca.

Trachea The trachea, colloquially called the windpipe, is a tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs.he epiglottis closes the opening to the larynx during swallowing. The trachea develops in the second month of development. It is lined with an epithelium that has goblet cells which produce protective mucins. An inflammatory condition, also involving the larynx and bronchi, called croup can result in a barking cough.

Cloacal disorders and diseases (Proceedings) The cloaca is comprised of three compartments: the proximal coprodeum, the middle urodeum, and the distal proctodeum.1-3 The coprodeum is the connection between the distal colon and the cloaca. The urodeum contains the openings of the ureters and the genital ducts. The coprodeal fold is a sphincter like ridge of tissue that separates the coprodeum from the urodeum. A second ridge within the cloacal lumen called the uroproctodeal fold separates the urodeum the proctodeum.

Picture of the Vagina The vagina is an elastic, muscular canal with a soft, flexible lining that provides lubrication and sensation. The vagina connects the uterus to the outside world. The vulva and labia form the entrance, and the cervix of the uterus protrudes into the vagina, forming the interior end. The vagina receives the penis during sexual intercourse and also serves as a conduit for menstrual flow from the uterus. During childbirth, the baby passes through the vagina (birth canal).

Frog The call or croak of a frog is unique to its species. Frogs create this sound by passing air through the larynx in the throat. In most calling frogs, the sound is amplified by one or more vocal sacs, membranes of skin under the throat or on the corner of the mouth, that distend during the amplification of the call.he use of the term frog in common names usually refers to species that are aquatic or semi-aquatic and have smooth, moist skins; the term toad generally refers to species that are terrestrial with dry, warty skins.

Enterobacter cloacae Enterobacter cloacae is a rod-shaped, gram-negative bacteria from the Enterobacteriaceae family. The size of this bacteria ranges from 0.3-0.6 x 0.8-2.0 μm. (13). Enterobacter cloacae lives in the mesophilic environment with its optimal temperature at 37 °C and uses its peritrichous flagella for movement.

Internal fertilization Via spermatophore, a sperm-containing cap placed by the male in the female's cloaca. Usually, the sperm is stored in spermathecae on the roof of the cloaca until it is needed at the time of oviposition. It is used by some salamander and newt species, by the arachnida, some insects and some mollusks.

cloaca The wall of the cloaca is covered with a many-layered epithelium. The ureter, the genital ducts (sperm ducts or oviducts), and the urinary bladder open into the cloaca. It is found in certain cyclostomes (hagfish) and fishes (sharks, skates, dipnoans and pipefish) and in all amphibians, reptiles, and birds.
