Indlela i‑Epididymis ne‑Vas Deferens ezisebenzisana ngayo ekuthuthweni kwesidoda nasekukhiqizeni inzalo

Manje, ake sikhulume nge-epididymis ne-vas deferens. Lawa womabili afana neqembu elizithintayo ohlelweni lokuzala lwesilisa. Zombili zibaluleke kakhulu ekuthuthweni kwesidoda futhi, ngokwethembeka, ngaphandle kwazo, ukuzala kowesilisa bekungeke kwenzeke nhlobo. Kungesinye salezo zinto ezenzeka ngemuva kwezindonga, kodwa esingakucabangi ngazo kaningi.

Yini i-epididymis futhi isebenza kanjani?

Ngakho-ke, okokuqala nje, yini i-epididymis? Uyishubhu elide eligobile elisemuva kwesende. Cabanga ngayo njengenkambu yokuqeqeshwa yesidoda. Umsebenzi we-epididymis uwukugcina nokuvuthisa isidoda. Zifika lapho zisanda kuphuma emasendeni, kodwa azikakulungeli ukusebenza. Zid necesita isikhathi sokuthuthuka. Futhi yilokho okuwumsebenzi we-epididymis. Konke kumayelana nokwenza leso sidoda silungele “umdlalo omkhulu”. Ngaphandle komsebenzi we-epididymis, isidoda besingeke sibe namandla noma ikhono lokubhukuda ngendlela efanele. Ukungabhukudi kusho ukungabikho kokufukamela [1].

Kodwa ungabuza ukuthi, yini umsebenzi we-epididymis? Hhayi-ke, okuwukuthintelwa kokugcina ekuthuthukisweni kwesidoda. Isidoda sivuthwa kulokhu kwakheka, sithola amandla asidingayo ukuze sifukamele iqanda. Ngakho-ke yebo, umsebenzi we-epididymis ubalulekile kakhulu ekuzaleni [2].

I-epididymis ikuphi?

Abantu bavame ukuzibuza, i-epididymis ikuphi? Isemuva kwamadoda, ifihlwe kahle. Indlela engcono kakhulu yokuyicabanga iwukubuka umdwebo we-epididymis. Isidoda sichitha isikhathi esithile sibakhona ngaphambi kokuba silungele ukusebenza, sivuthwa ezinsukwini ezimbalwa.

Lapho isidoda sesivuthiwe, sihamba sisuka ku-epididymis singena ku-vas deferens. Kufana nomjaho wokudluliselana, lapho ilungu elilodwa leqembu (i-epididymis) lidlulisa ibhathoni (isidoda) kwelandelayo (i-vas deferens) [3].

Yini i-vas deferens futhi yenzani?

I-vas deferens yindawo elandelayo. Uhlobo lweshubhu elude, oluvame ukubizwa ngokuthi ishuba le-spem, olubhekele ukuhambisa isidoda sisuka ku-epididymis siye ku-urethra. Kodwa ngempela, siyini isizathu sokuba khona kwe-vas deferens? Hhayi-ke, liyindlela enkulu yesidoda. Umsebenzi we-vas deferens uwukuqinisekisa ukuthi isidoda sifinyelela lapho kufanele siye khona ngesikhathi sokuchama ngesidoda [4].

Umsebenzi we-vas deferens ubalulekile ngendlela efanayo nomsebenzi owenziwa yi-epididymis. Ibhuloho, iyithuthi. Cabanga ngayo njengenkonzo yokuletha, eqinisekisa ukuthi isidoda sifinyelela lapho siya khona. Umsebenzi we-vas deferens wenza isiqiniseko sokuthi isidoda sikhishwa ngesikhathi sokuchama okunezidoda futhi sixutshwe noketshezi lwe-seminal [5].

Uthakazelela ukwazi ukuthi kuyini i-vas deferens? Iyona msele efanayo eqhubeka isuka ku-epididymis iye ku-urethra, futhi ibaluleke kakhulu ekuthuthweni kwesidoda. Umdwebo we-vas deferens ungakusiza ukubona kahle ukuthi idlula kuphi, ifihlwe ngaphakathi emzimbeni, yenze umsebenzi wayo ngasese [6].

Indlela i-epididymis ne-vas deferens ezisebenzisana ngayo

I-epididymis ne-vas deferens zifana nabalingani. Omunye ugcina futhi uvundulula isidoda, omunye usithutha ukuze kuphume isidoda. Uma kungekho oyedwa, omunye ngeke asebenze kahle. Umsebenzi we-epididymis ukwenza isiqiniseko sokuthi isidoda sivuthwa futhi sithole ikhono lokubhukuda. Ngesikhathi esifanayo, i-vas deferens ixhuma ku-urethra, lapho isidoda sixubana khona noketshezi lwe-seminal. Ngakho-ke, ngesikhathi sokuchama okunezidoda, i-epididymis ne-vas deferens basebenza ndawonye ukwenza isiqiniseko sokuthi isidoda sesilungele ukukhishwa [7].

Futhi umbuzo obalulekile: yini umsebenzi we-vas deferens? Umsebenzi wayo nje ukwenza isiqiniseko sokuthi isidoda sihanjiswa, ngaphandle kokuphazamiseka, siye ku-urethra, lapho sikhishwa khona emzimbeni. Zonke lezi zinhlelo zithembele kulokhu kusebenza ngokushelelayo, futhi noma yikuphi ukuvinjwa noma ukulimala ku-vas deferens kungasho izinkinga [8].

Kwenzekani uma kukhona ukulimala?

Uma kukhona ukulimala ku-epididymis noma ku-vas deferens, kungaholela ezinkingeni ezinkulu zokungazali. Ukuvuvukala, njenge-epididymitis, kungabangela ukuvuvuka ku-epididymis, okuthi kuvimbe ukugeleza kwesidoda. Ngokufanayo, ukuvinjwa ku-vas deferens kungavimbela isidoda ekufinyeleleni ku-urethra, kuthinte ukuchama okunezidoda, futhi ekugcineni, ukukhulelwa [9].

Odokotela bavame ukuxilonga izinkinga ezinjalo ngokubheka isithombe (diagram) se-epididymis noma isithombe se-vas deferens. Lokhu kungabasiza ukuba babone noma imaphi amabhlogo noma izinkinga zesakhiwo ezivimbela isidoda ekuthatheni uhambo kahle ku-vas deferens. Baphinde bahlolisiswe nezingxenye zesikhwama sezende, okuhlanganisa izende, i-epididymis, ne-vas deferens, ukuze babheke noma yiziphi izingqinamba zesakhiwo [10].

Yiziphi amapayipi ahambisa i-sperm ngqo aya ku-epididymis?

Ngaphambi kokuba isidoda sifinyelele ku-epididymis, sidinga ukuhamba ngemigudu emincane. Pho, yiziphi izintshingo ezithwala isidoda ngqo liye ku-epididymis? Lezi yiziteshi ezikhiphayo (efferent ducts), ezihambisa isidoda zisuka ezindeni ziye ku-epididymis ukuze sigcinwe futhi sivuthwe. Lapha yilapho isidoda sivuthwa khona futhi silungele ukuya esigabeni esilandelayo: i-vas deferens [11].

Okubalulekile Ekugcineni

Ngamafuphi, i-epididymis ne-vas deferens izingxenye ezibalulekile ekuzaleni kwabesilisa. Ukugcina izende zibanda kubonisiwe ukuthi kusekela ukukhiqizwa kwesidoda okungcono kanye nempilo yezende iyonke. Zisebenzisana ukuqinisekisa ukuthi isidoda sivuthwa futhi sithuthwa ngendlela efanele ngesikhathi sokuchama. Umsebenzi we-epididymis umayelana nokuvuthwa kwesidoda, kanti umsebenzi we-vas deferens uqinisekisa ukuthi isidoda sithuthwa siya ku-urethra. Ukugcina lezi zakhiwo ziphilile kubalulekile kunoma ubani ofuna ukukhulelwa [12]. Izithasiselo zokuzala kwabesilisa ezinezithako ezifana ne-Zinc, i-Folate, ne-L-Carnitine zingasiza ukusekela ikhwalithi yesidoda nempilo yokuzala.

Imibuzo ejwayelekile

Iyini umsebenzi we-vas deferens?

Umsebenzi we-vas deferens ukuhambisa i-sperm evuthiwe isuka ku-epididymis iye ku-urethra.

Uyini umsebenzi we-epididymis?

Umsebenzi we-epididymis ubalulekile ukuqinisekisa ukuthi i-sperm ivuthwa kahle. Uma seyivuthiwe, ithuthunyiselwa nge-vas deferens, kuqinisekiswe ukuthi i-sperm ikhishwa ngempumelelo ngesikhathi se-ejaculation. Ngakho-ke, uyini umsebenzi we-epididymis? Ngokufingqiwe, iqinisekisa ukuthi i-sperm isilungile ukuze ichumise ngesikhathi esiphuma ngawo emzimbeni.

Yiziphi amapayipi ahambisa i-sperm ngqo aya ku-epididymis?

Ama-efferent ducts ahambisa i-sperm ngqo aya ku-epididymis esuka ezendeni.

Ingabe ukuvinjelwa ku-vas deferens kungadala ukungazali?

Yebo, ukuvinjelwa ku-vas defrens noma ku-vas deference kungavimba i-sperm ekufinyeleleni ku-urethra, okubangela izinkinga zokuzala.

Iyini inhloso ye-vas deferens?

Inhloso ye-vas deferens ukuhambisa i-sperm isuka ku-epididymis iye ku-urethra ngesikhathi sokuchama okuhlangene (i-ejaculation).
