Unjani ilungu lomntu? Ubonakala njani ipenisi enempilo?Isini sesini somntu senza umsebenzi obaluleke kakhulu ebomini ngamnye umntu. Ungomnye wezitho zenkqubo yokuzala kunye nenye yezinto ezibini apho abantu bazalwa khona. I-anatomy, i-genitalia yangaphandle neyangaphakathi ibizwa ngokuba: i-penis, i-scrotum, i-testicles, i-epididymis, vas deferens, i-prostate gland kunye ne-vesicles vesicles.
Unjani ilungu lomntu?
Kuyaziwa ukuba izitho zesini zesini zihlukaniswe ngaphakathi nangaphandle. Masiqwalasele ngakumbi indlela ipensi yomntu isebenza ngayo.
Izitho zangasese zangaphandle ziquka:
I-penis inamalungu amabini: isiseko (ingcambu) kunye nomzimba (trunk). I-trunk isakhiwe ngoncedo lwemizimba ye-cavernous ne-spongy, i-indentations ezaliswe ngegazi. Efihliweyo ngentloko epholileyo yecenis, iqukethe inani elikhulu leengqungquthela ezivelisa isilisa. Intloko ibuhlungu kakhulu ngenxa yexinaniso enkulu yokupheliswa kwentsholongwane kuyo, ekukhokelela ekukholweni. Ukuvula ngentloko yentloko kuthiwa ukuphuma kwi-urethra kwaye usebenzela ukucoca umchamo kunye neenja.
I-scrotum yintlobo yesitoreji se-testicles esinezihlunu kunye nekhumba elinesigqabha elihlanganiswe ubuncinane beenwele.
Izitho zangasese zangaphakathi ziquka:
Amaqanda adlala indima enkulu kwenye yeyona misebenzi ebalulekileyo yomzimba wesilisa - ukwakheka kwe-spermatozoa. Ziyaziwa ngumbutho okhethekileyo obonelela ngeqondo elifanelekileyo lokubaluleka ekudalweni nasekugcinweni komsebenzi obalulekileyo we-spermatozoa. Ngokomyinge, ukushisa okulungileyo kubo ngama-degrees angama-34, ukuze ekushiseni kungabikho ukufudumala emzimbeni, i-scrotum iyahla, kwaye kubanda, ngokuchaseneyo, ithotshelwe kuyo. Khumbula ukuba ukushisa okuphezulu kwamathambo kungakhokelela ekubeni ubuchule bendoda yokuqhelisa buza buthathaka kwiinyanga ezintandathu.
I-vas deferens yi-conductor, apho, ngoncedo lwee-contractions ezifana ne-orgasm nge-canalinal canal kunye ne-prostate gland, i-sperm iyaxutywa emzimbeni.
Inomdla! Ukunyakaza kwe-spermatozoa kutyhafa imfihlo ekhethekileyo, eyinxalenye yesidoda, eveliswa yi-prostate gland.
Esinye seziqendu zesambulo siyimfihlo eyenziwa ngama-vesicles, okubandakanya i-fructose, ezalisa isibalo ngamandla kunye nokwandisa ukunyanzelisa.
Ubonakala njani ipenisi enempilo?
Ngokumalunga nobukhulu bepenisi, ngoko akukho mgangatho oqhelekileyo, ubude kunye nobukhulu bomntu ngamnye ngabanye. Nangona kunjalo, i-statistic yesiganeko ilungu elikhulu lokuphumla lilisentimitha ezilishumi. Ngenxa yenani elikhulu lokuphela kwezigulane eziphezu kwayo, linakho ukukhula ngobukhulu kwaye lifikelela kuma-16 okanye ngaphezulu kwamentimitha. Oku kuthiwa ukulungiswa.
Yiloo nto igqirha lesini elibukeka ngathi lisuka ngaphakathi. Kuya kubonakala kulula kwaye kungabonakali ngaphandle, kunesakhiwo esiyinkimbinkimbi ngaphakathi. Ngokuqinisekileyo lidlala indima ebalulekileyo ekuqhubekeni koluntu.
