Frog Dissection 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. Those of the female system are the ovaries, oviducts, uteri, and cloaca. The testes produce sperm, or male sex cells, which move through sperm ducts, tubes that carry sperm into the cloaca, from which the sperm move outside the body. The ovaries produce eggs, or female sex cells, which move through oviducts into the uteri, then through the cloaca outside the body.

- The semen carries sperm cells through the vaginal canal to the uterus where the sperm seek out the female egg for fertilization. Also, when a man urinates, the flow leaves his body through the urethral opening. Urethra. The urethra is a duct, or tube, that transports fluids from the inside of the body to the outside. In both men and women, the urethra is connected to the bladder and is used to pass urine out of the body. In males, however, the urethra is also connected to the “accessory glands,” which produce semen, and to the vas deferens, the duct that brings the sperm from the epididymis.

Fertilization Sperm transport. sperm flagellum assist, channels in the cervical mucus help direct the sperm, muscular contractions of the uterine channel assist, sperm have 50% chance of making it into the correct tube, Eddy currents created by the cilia movements assist the sperm through the uterine and uterine tube.vulation steps. Follicle wall breaks down (enzymatic breakdown that causes the follicle to collapse), oocyte is expelled into perotoneal cavity (with zona pellucida, corona radiata, and cumulus cells), oocyte complex is picked up by uterine tube (cilia).

Chapter 31 - Urinary Elimination Is the exit passageway for urine from the bladder. -In women, it is short 3 to 5 cm, a factor that increases the opportunity for bacteria to enter the urinary system. -In men, the urethra is longer, about 20 cm and serves to transport both semen and urine.

EXCRETION IN AMOEBA EXCRETION IN AMOEBA. Amoeba is a unicellular organism found in fresh water. In amoeba carbon dioxide and ammonia are the main waster materials. These waste materials are excreted out by the process of diffusion through general body surface. In amoeba, contractile vacuoles also play some role in the removal of waste materials. The waste materials present in the cytoplasm of amoeba enters the contractile vacuole.

Avian Reproductive SystemâMale Each vas deferens opens into a small bump, or papilla, on the back wall of the cloaca. The papillae (plural of papilla) serve as the mating organs. (The rudimentary copulatory organ located on the middle and front portion of the cloaca is inaccurately named because the chicken does not use it for copulation, or mating.

Fertility Education & Training In this mucus, sperm can swim up into the cervix and survive for 3-6 days. 1  The “mesh” mucus blocks the passage of sperm, preventing pregnancy from occurring.  The “motorway” mucus prolongs the life of sperm and enables them to swim through the cervix and womb and into the fallopian tubes, in search of the egg.

Fallopian Tube Anatomy Sperm enter the fallopian tube through the uterus, and eggs enter from the ovarian or fimbrial end of the tube. When the fallopian tubes are blocked, sperm and eggs are kept apart and fertilization is prevented. Ligation means to apply a ligature or tie, and tubal ligation is often called “tying” the tubes.

How do birds mate? Pictures of dove (pigeon family) mating How do birds mate? Which organs do the male bird use to mate? Do female birds have organs? Birds mate by joining at their cloaca so that the sperm of the male bird can go from his cloaca to the female's. Confused? Here's a quick overview on how birds reproduce, have sex or mate with some amateur pictures.

- Millions of sperms are deposited into the vagina during sexual intercourse. The sperms make their way through the cervix into the uterus and then on to the fallopian tubes. As they swim along this way their numbers decline. Only a few hundred sperm will get close to the egg. During the trip, sperm prepare themselves to meet the egg by subtle alterations of their heads and movement patterns.

Fertility Education & Training The oestrogen also stimulates the glands in the cervix to disperse the mesh mucus and produce instead a wet slippery mucus with swimming lanes along which sperm can move easily, as if on a “motorway”. This new mucus is alkaline and contains glucose and other nutrients vital to sperm survival.
