Isakhiwo umthondo kanye nezinye izitho besilisa zangasese

Izitho zangasese (owesilisa) zihlukaniswe zangaphakathi nezangaphandle. I yangaphandle zihlanganisa scrotum futhi umthondo, futhi yangaphakathi - efihlekile emehlweni iso - the testes, epididymis, intambo spermatic kanye tubercle, umdlavuza (bulbar, urethral futhi wendlala) kanye le vesicles kwesidoda. Isakhiwo izitho besilisa subordinated umsebenzi wabo oyinhloko - ukuzala futhi ukudluliswa kwe-zofuzo Imininingwane umlingani.

Ngazo zonke izikhathi, ukunakwa kakhulu sakhokhwa umthondo. Ezinye izinhlaka undeservedly ukhohliwe futhi wakhumbula kuphela esimweni isifo, kodwa iwuphawu ngobudoda - Ilungu - nakanjani waba isihloko isithakazelo abesilisa isigamu besifazane emphakathini. Ngisho abantu basendulo bakhuleka ilungu, njengoba unkulunkulu othile, ngisho owazenza ngabo zonke izinhlobo amasiko. Futhi amalungu itshe bancishwa ubumsulwa ...

Sekuyisikhathi eside ilungu isakhiwo kwaba zingakwazi ukufunda ngokuqonda. Ngokwesibonelo, abantu basendulo babekholelwa ukuthi ngesikhathi ukwakhiwa ligcwele umoya - manje lezi izibikezelo ngokuphelele ziyadalulwa. Kuphela ukuthuthukiswa anatomy Ephakathi, ngaphansi yobuhlungu kobufundisi isijeziso odokotela aseqalile ukufunda umzimba womuntu, futhi nalo - kanye nesakhiwo wenduku.

I umthondo siqukethe umzimba, inhloko, ijwabu futhi umlomo urethra. ilungu lomzimba obuphelele - kusukela amasentimitha ayisithupha kwabayishumi ngesikhathi ukuphumula futhi girth - eziyisithupha ngamasentimitha. Shona wenduku kufihliwe ngaphansi ijwabu, esivikela ke ekulimaleni lokukhanda. Ekupheleni ikhanda umlomo urethra, okuyinto ukhululeka isidoda kanye nomchamo. izingxenye ezinjalo kungaba zibukeke ukwehlukana umthondo. I kwangaphakathi ilungu isakhiwo luyindida kakhulu. Yonke umzimba wenduku siqukethe cavernosa corpora. Ngesikhathi ukwakhiwa e le cavernosa corpora luyanda blood pressure, lelo okuthi lapho voltage namandla ngokukhethekile ingavuthi ilingane Imininingwane blood pressure. Ngokwe Ukuklanywa komzimba ukukhumbuza amasilinda sizungezwe ijazi amaprotheni, okwenzeka nhlangothi zombili wenduku. imikhawulo yabo Abut futhi unamathele ithambo pubic, kanjalo zakha impande. Urethra yedlula izidumbu, ngawo umchamo ohamba ngayo phandle nangaphakathi ngokusebenzisa orifice (ukuvulwa ekhanda wenduku). Ilungu kulesakhiwo ngakho wahlela ukuba isidoda kanye nomchamo ngokuvamile ungalokothi uhlanganise - uyena owenza lokhu idolo ekhethekile zigcwala ngesikhathi sokuya ocansini futhi ukucindezela efana urethra.

Esikhathini scrotum, udonga engaphakathi ihlukaniswe yaba izingxenye ezimbili, kukhona testes nentambo spermatic. Emasendeni banesibopho imisebenzi esemqoka - ukukhiqizwa kwesidoda futhi androgens. Isici esivelele sesimiso emasendeni wukuthi lokushisa yabo ayihambisani izinga lokushisa emzimbeni jikelele - ku testes kuyinto degrees ezimbili aphansi. Okunjalo "ifriji umphumela" ngokuqondile uhlinzeka ngokuphepha spermatozoa.

Epididymis - lokhu okukhethekile emizimbeni, okuyinto kulawulwa androgens. Bazi ukuthi banesibophezelo umjikelezo ogcwele kwesidoda, ozobakhona amasonto amabili - kwaba phakathi nalesi sikhathi ukuthi isidoda finyelela khula lapho bayakwazi zalisa insikazi lwegciwane cell. Ukuze spermatozoa zadluliselwa ukuba iqanda, zingabantu ixutshwe intambo spermatic imfihlo, ecebile izakhamzimba. Kulesi spermatozoa liquid amandla ukusekela umzimba wabo, kanye lula ukunyakaza kwabo. Kuncike zonke yalo msebenzi ukuze igazi eligciniwe. Imithambo kanye emithanjeni abazondla iqanda ebiyelwe intambo spermatic.

Enye umzimba obalulekile - endlaleni engasesinyeni. Kuyinto unesibopho ejaculate ivolumu, okwandisa ke ngenxa liquefaction kwesidoda, isidoda amaseli ukumelana namagciwane akuzona bondability.

ilungu isakhiwo kungase bachezuke kuyinsakavukela. Phezu ukuthola zokugula njengoba isidingo sokuya kudokotela ngokushesha ngangokunokwenzeka ukulondoloza umsebenzi nocansi obengeziwe amadoda.
