Kwilizwe lanamhlanje leengubo-yintoni na?

Akunakwenzeka ukuseka iminyaka yeendlela zokuqala zokuhambisa amanzi emhlabathini. I-cloacas endala yeRoma yakudala-uClaaca Maxima, okukhankanywe okokuqala, nokuba yi-IIV, okanye kwi-IV leminyaka ye-BC, abaphandi abakhokelayo kwi-Etruscan masters, kwimeko ethile ngaphambili. Okokuthi, umntu akayena isilwanyana, kwaye, kunye nokwakhiwa kwezindlu, ngoko nangoko waqala ukumisa iziza.

I-Cloaca njengenxalenye yenkqubo yokuthuthwa kwamanzi

Ngohlobo lwangaphambili lwezakhiwo zokwakha, amagama abo aseLatin ayamangalisi. Cloaca - yintoni le nto? Ukuba uguqulela isenzi esithi "i-cloacare" ngesiRashiya, iyavela - ibe yinqambi, ibe yinqambi. Ngenxa yoko i-cloaca ngumzila onento engcolileyo, kunye nokuthuthwa kwamanzi okanye indawo yokuqokelela kwabo, okanye isakhiwo sokubakhupha. Kukho imizi yakudala yaseYurophu apho le mijelo yamatye ifumaneka ngaphandle kwezitrato, kodwa, njengomthetho, iindawo zokuthuthwa kwamanzi ziphantsi komhlaba, ngamanye amaxesha zimelela imizi epheleleyo. Ubunzulu beParis, obuchazwe kwiincwadana ezininzi, ziye zatshatyalaliswa ngokuthandana. Lapha ubulungisa bulawulwa (nangona bukhulu kakhulu), ukufumana isiphephelo esitshutshisayo safunyanwa. Ngoko ingubo - yintoni na? KwiRoma yanamhlanje-indawo evelele kakhulu yokutyelela.

Cloaca nje ngomzobo

Indima ekhethekileyo yeli gama kwincwadi. Ukususela kwixesha elidlulileyo i-cloaca lalibizwa ngokuba yiyo yonke into engcolileyo, engcolileyo, engafanelekiyo, enyanyekayo njengokwenyama (kwindawo enganakuxhaswa), nangengqondo engokomoya - iingcamango ezingathandekiyo neminqweno. Yonke into evela kwisimo esingokoqobo kunye nomfuziselo ongaphezu kokuthunga kakubi, iprintwe negama. Kwaye ku futshane kufuneka ubeke izicingo.

Ixesha kwi-biology

Kodwa oku akukona nje ubunjineli kunye nekota yokubhala. Udibana ne-ornithology - isayensi ehlola iintaka. I-Cloacas kwiintaka, njengezinye iintlanzi kunye ne-cyclostomes (i-vertebrates engaphantsi), kuzo zonke izilwanyana ezihlambulukileyo kunye nama-amphibians (echidna, platypus, njl njl.) Yintlambo ethile, eyona nxalenye ephakanyisiweyo yokuphela kwesondlo sokutya. Kwiintaka, i-urethra kunye ne-oviduct ephuma kuyo. Ngoko ke, ubuso beeqanda zeentaka eziza kumashishini kufuneka zicutshungulwe. Kunzima ukugqithisa ukubaluleka kweli candelo kwiintaka, kuba insemination (kwaye, ngokwemvelo, ukuvelisa) yenziwa yiinyoni ngenxa yenkqubo ebizwa ngokuthi "kiss of the cloaca".

Ukuchazwa ngonyango

Kwimichiza, kwakhona, eli gama likhoyo. I-Cloaca ebantwini ikhona kwinqanaba lombungu, ngoko kwinkqubo yophuhliso liguqulwa libe zimbini, ezihlukeneyo-i-genitourinary ne-rectal. Zomibini zokuqala (urogenital) kunye neyesibini (ii-rectal) zineendawo zokufikelela ezizimeleyo kumgangatho womzimba womntu. Bahlukene phakathi kwabo nge-perineum. Oku, ngoko kuthetha, ukuphilisa umzimba. Kodwa kwiyeza, eli gama lifunyenwe nangona egameni lesi sifo, esivela njengesiphumo esingaqhelekanga sokuphuhliswa kwe-intrauterine. Ukusetyenziswa kule meko, i-cloaca - yintoni na? Le yinto engabonakaliyo neyinkimbinkimbi yokuphuhliswa kommandla we- rectum. Ibizwa ngokuthi "congenital cloaca" yaye ifumaneka kuphela kumantombazana. Ingundoqo yesi sifo kukuba i-urethra, isondo kunye neengxenyana zixhunyaniswe kwisinye isiqhelo esifanayo, i-anus ayikho ngokupheleleyo. Kufunyanwa ngokukhawuleza emva kokuzalwa komntwana. Ukunyangwa kwesi sifo kubakho kuphela ngoncedo lwenkqubo yokucubungula kakhulu.

Ixesha kwihlabathi lanamhlanje

Kungekudala, igama elithi "ingubo" laqala ukuvela rhoqo. Kwaye kwenzeka kuba ukusuka kwinqanaba elincinci elithile lithe lafika kwindawo yokuphela kwimibala yekhompyutheni kunye neprose yamhlanje ("Cloaca" nguEdgar Doctorow). Yaye ukuba ayibonakali egameni lomdlalo, kuthatha inxalenye enkulu. Umzekelo unokusebenza njengengubo yeDalaren ukusuka kumdlalo ogqithiseleyo "World of Warcraft". Cloaca - yiyiphi into eWOW? Lo ngumzi wonke kunye namaqhawe akhe kunye nemibuzo. Ibala lezopolitiko liye lafaka isandla ekukhuthazeni eli gama.
