Kunzwisisa Sisitimu Yekubereka Mukati
Katsi, dzine hunhu hwadzo husinganzwisisike uye hwakazvimiririra, dzagara dzichifadza vanhu. Chimwe chezvinhu zvisinganyanyozivikanwa, asi zvinonakidza zvikuru nezvezvisikwa izvi inzira yadzo yekubereka. Kunzwisisa kuoma kwekubereka kwekatsi kunogona kupa ruzivo rwakakosha mumaitiro adzo, zvinodiwa pahutano, uye manejimendi yevanhu. Chinyorwa chino chinotarisa mumaumbirwo, mashandiro emuviri, uye maitiro ekubereka ekatsi, zvichijekesa zvinoitika panguva yekubereka uye zvazvinoreva kune varidzi vekatsi nevezvipfuyo.
Anatomical Overview
Maitiro ekubereka mumakati akasiyana mune ese ari maviri echirume neechikadzi, zvichienderana nemabasa avo mukubereka.
Katsi dzechikadzi (Mahosi)
Sisitimu yekubereka yevakadzi inosanganisira maovari, maoviducts, chibereko, cervix, vagina, uye vulva.
– Mazai: Ari pedyo neitsvo, mazai anoburitsa mazai (ova) nemahormone akadai seestrogen neprogesterone. Mahormone aya anodzora kutenderera kwekubereka nepamuviri.
– Matubhu emudumbu: Anozivikanwawo semachubhu emudumbu, machubhu aya matete anotakura ova kubva mumazai kuenda kuchibereko.
– Chizvaro: Nhengo ine chimiro cheY apo mazai akaberekeswa anodyarwa okura kuita katsi. Nyanga dzechibereko ndidzo dzinobatana uye dzinokura.
– Muromo wechibereko: Chikamu chidiki diki chechibereko chinotungamira kunhengo yechikadzi.
– Nhumbu: Mugero wetsandanyama unobatanidza muromo wechibereko nenhengo dzekunze dzepabonde (vulva).
– Kusviba: Chikamu chekunze chenhengo dzechikadzi.
Katsi dzechirume (Toms)
Sisitimu yekubereka yevarume ine matestes, epididymis, vas deferens, urethra, penis, uye magland anobatsira.
– Matende: Ari mudumbu, matende anoburitsa urume ne testosterone.
– Epididymis: Chubhu yakamonerwa inokura mbeu yemurume yochengetwa.
– Vas deferens: Inobvisa mbeu yemurume yakura kubva mu epididymis panguva yekubuda kwembeu.
– Urethra: Chubhu inotakura weti nembeu kubva mumuviri ichienda kunhengo yemurume.
– Nhengo yemurume: Ine tumababi tunomutsa mazai emukadzi panguva yekusangana kwemukadzi.
– Zvishongo zvekuwedzera: Zvinogadzira mvura inoyerera kuti ipe simba uye ifambise mbeu yemurume.
Kutenderera Kwenguva Dzepasi
Katsi dzechikadzi dzinosangana nedambudziko re "estrous cycle", rinowanzonzi "mukupisa." Kutenderera uku kune matanho akati wandei anogadzirira mambokadzi kusangana, kubereka, uye kubata pamuviri.
1. Proestrus: Danho rekutanga iri, rinotora mazuva 1-2, rinosanganisira kuwedzera kushanda uye hunhu hwerudo. Madzimai anogona kutanga kutaura zvakawanda uye kutsvaga kutariswa, asi haasati agamuchira kusangana.
2. Estrus: Danho rechokwadi rekupisa rinotora mazuva 4-10. Munguva iyi, mambokadzi anoratidza zviratidzo zvakajeka zvekugadzirira kurara nemukadzi, zvinosanganisira kuwedzera kwekurira, kusagadzikana, hunhu hwerudo, uye kutora nzvimbo ye lordosis (kusimudza chikamu chekumashure). Kana kurara nemukadzi kukaitika, ovulation inokonzerwa.
3. Interestrus (kana kuberekesana kusina kuitika): Kana mambokadzi akasaberekesana, anopinda munguva pfupi yekusagamuchira nhumbu kwenguva inosvika vhiki imwe kusvika mbiri asati adzokera kuproestrus.
4. Kubuda kwembeu: Kana ovulation ikaburitswa uye kubereka, mambokadzi anopinda mudiestrus, uko pamuviri unoitika. Kana ovulation ikaburitswa pasina kubereka, mambokadzi anogona kuita pamuviri wenhema kwemazuva angangoita 30-40.
5. Kusaita zvepabonde: Nguva iyi yekusaita zvepabonde inonyanya kuitika mumatsutso nemuchando apo nguva yemasikati inenge ipfupi, zvichikanganisa kugadzirwa kwemahormone.
Kusangana uye Kubata Pamuviri
Katsi dzinoonekwa sedzinoburitsa mazai anokonzerwa nekubereka, zvichireva kuti ovulation inongoitika chete mushure mekusangana kwemurume. Nhengo yemurume ine minzwa inosimudzira nzira yekubereka yemambokadzi, zvichikonzera kuburitswa kwemazai. Maitiro aya anowedzera mikana yekubereka zvakanaka.
Kusangana kwemhasuru kunoitika kwenguva pfupi, kunongotora masekondi mashoma kusvika kuminiti. Zvisinei, madzimambo anogona kusangana nemhasuru dzakawanda kwemazuva akati wandei, maitiro anozivikanwa se superfecundation, zvichikonzera kuti mombe dzibereke vanababa vakawanda.
Kubata pamuviri uye kubereka
Kubata pamuviri kwekatsi kunotora mazuva angangoita 63-65. Munguva iyi, mambokadzi anochinja zvinhu zvakawanda:
– Kuchinja Kwemaitiro: Mambokadzi vane pamuviri vanogona kuwedzera rudo kana, zvakasiyana, kuva vega.
– Kuchinja Kwemuviri: Paunenge uine pamuviri, dumbu ramambokadzi rinokura, uye mazamu anova pachena uye anopenya.
– Zvinodiwa Pakudya: Kudya kwakawedzerwa uye zvinodiwa pakudya zvinovaka muviri kuti zvitsigire maembryo ari kukura.
Sezvo nguva yekusununguka, kana kuti nzira yekubereka, yava kusvika, mambokadzi vanowanzotsvaga nzvimbo dzakanyarara, dzakavanda dzekuberekera. Maitiro ekusununguka, kana kuti kuva mambokadzi, anosanganisira kutevedzana kwekubata kwedumbu kunobatsira pakubereka katsi. Danho rekusununguka rine matanho matatu:
1. Danho rekutanga kusununguka: Mambokadzi anotadza kuzorora uye anogona kuramba chikafu. Maitiro ekuvata matendere anowedzera paanogadzirira nzvimbo yakachengeteka yekuzvarira.
2. Kushanda nesimba: Kubata kwakasimba kunoita kuti katsi dzibereke. Kazhinji, katsi imwe neimwe inoberekwa maminetsi gumi kusvika makumi matanhatu ega ega, kunyange zvazvo dzimwe nguva dzichigona kureba. Mambokadzi anochenesa katsi imwe neimwe ocheka rukuvhute.
3. Chikamu chekuzvarwa: Mambokadzi anoramba achichenesa vana vake vekatsi uye anogona kudya placenta kuti awane chikafu.
Kutarisirwa kweVana Vasati Vazvarwa uye Kuyamwisa
Mushure mekubereka, mambokadzi vanopinda munguva yekuyamwisa kuti vape vana vavo mukaka wakapfuma mune zvinovaka muviri zvakakosha uye masoja ekudzivirira chirwere. Zvakakosha kuti varidzi vembwa vave nechokwadi chekuti mambokadzi ane chikafu nemvura yakakwana kuti awane zvekudya zvakawanda panguva iyi.
Katsi dzinowanzoyamwisa kwemavhiki matanhatu kusvika masere dzisati dzatanga kudya chikafu chakasimba. Kubva pamavhiki mana, varidzi vanogona kuisa chikafu chekatsi nemvura kuti zvibatsire pakurumurwa.
Kunetsekana Kweutano hweKubereka
Kunzwisisa nzira dzekubereka kwakakosha pakuziva matambudziko ehutano anogona kuitika mukati. Zvinonyanya kushungurudza zvinosanganisira:
– Pyometra: Utachiona hwemudumbu hunogona kutyisidzira hupenyu hunowanzoonekwa mumadzishe akura asina kubereka.
– Dystocia: Kurwadziwa kana kuti kuvharika kwekusununguka, kunoda rubatsiro rwechiremba wemhuka.
– Matumbu emuzamu: Anowanzoonekwa mumadzimai asina kubereka, zvichiita kuti pave nekuongororwa hutano nguva nenguva.
Kune vane usimbe, zvinonetsa zvinowanzo sanganisira:
– Cryptorchidism: Kukundikana kwebvudzi rimwe chete kana ese ari maviri kudonha, zvichiwedzera njodzi yekenza yemazamu.
– Prostatitis: Kuzvimba kweprostate gland, kazhinji kunokonzerwa nehutachiona.
mhedziso
Kunzwisisa nzira yekubereka yekatsi kwakakosha pakuona hutano hwavo nekugara zvakanaka. Kubva padanho rekufamba kwemhuka kusvika pamatambudziko ekubereka, pamuviri, uye kutarisirwa mushure mekusununguka, chimwe nechimwe chinhu chinoita basa rakakosha pakuona mhando dzekatsi. Nekuwana ruzivo rwakadzama nezvemuviri wadzo wekubereka, varidzi vekatsi nevarapi vemhuka vanogona kubata zviri nani kubereka, kugadzirisa matambudziko ehutano, uye kubatsira mukutarisira kwakanaka uye kudzora huwandu hwekatsi dzedu.
