Mienzaniso yeMibvunzo Inokurukura Hukama Huripo Pakati Pemagadzirirwo Enhengo MuSistimu Yekubereka
Sisitimu yekubereka ndeimwe yenhengo dzakaoma uye dzinonakidza muzvinhu zvipenyu, kunyanya vanhu. Ine zvimiro zvakasiyana-siyana uye nhengo dzinoshanda pamwe chete kuti dzizadzise chinangwa chikuru: kubereka. Kunzwisisa kuti chimiro chimwe nechimwe nenhengo iri mukati meiyi sisitimu zvinobatana uye zvinoshanda sei kwakakosha, mudzidzo uye mukurapa. Muchinyorwa chino, tichakurukura mimwe mienzaniso yezvinetso maererano nehukama hwenhengo dziri mukati meiyi sisitimu yekubereka, pamwe nekukurukura nezvedambudziko rega rega.
Mubvunzo 1: Mazai echibereko nechibereko zvine hukama hwakadii panguva yekuenda kumwedzi?
Kukurukurirana:
Mazai echibereko nechibereko inhengo mbiri huru munhengo dzekubereka dzevakadzi dzinoita basa rakakosha mumwedzi. Mazai echibereko anogadzira mazai (ova) nemahormone akadai seestrogen neprogesterone. Mwedzi wega wega, rimwe remazai maviri aya rinoburitsa zai nenzira inonzi ovulation.
Mushure mekubuda kwembeu, zai rinobuda rinofamba richidzika nemuchubhu yeFallopian richinopinda muchibereko. Panguva iyi, mahormone anogadzirwa nemaovari anogadzirira chibereko (endometrium) kuti chigamuchire zai rakabatanidzwa. Kana kusangana kwembeu kukasaitika, huwandu hwemahormone hunoderera, zvichiita kuti endometrium ibude sekuenda kumwedzi. Saka, hukama huripo pakati pemaovari nechibereko panguva yekuenda kumwedzi huri kunyanya mukushanda kwemahormone nezvirongwa kuti zvive nyore kubereka.
Mubvunzo 2: Tsanangura basa remachubhu eFallopian mukuita kwefeteraini uye hukama hwawo nezvimwe zvimiro.
Kukurukurirana:
Machubhu eFallopian, anozivikanwawo semachubhu efallopian, ndiwo machubhu anobatanidza maovari nechibereko. Basa rawo guru nderekubata zai rinoburitswa nechibereko uye kushanda senzvimbo inowanzo sangana. Mushure mekuvhurwa kwechibereko, fimbriae (zvimiro zvakaita seminwe zviri kumagumo kwechubhu yeFallopian) inobata zai roritungamirira kupinda muchubhu.
Panguva yekusangana kwembeu, mbeu inopinda nepanhengo yemukadzi nepachibereko inosangana nezai muchubhu yefallopian. Kana kusangana kwembeu kukabudirira, zai rakasangana nembeu (zygote) rinoenda kuchibereko kuti riiswe. Kufamba uku kunofambiswa ne cilia uye kusungwa kwetsandanyama kwakatsetseka muchubhu yefallopian, izvo zvinosundidzira zygote kuchibereko. Kubatana nezvimwe zvivako, zvakaita sechibereko, kwakakosha, sezvo zvichipa nzvimbo yakakodzera yekukura kwembeu.
Mubvunzo 3: Matende neprostate gland zvine hukama hwakadii nekugadzirwa nekuburitswa kwembeu?
Kukurukurirana:
Matestes neprostate gland zvikamu zvakakosha zvehurongwa hwekubereka hwevarume, zvichishanda pamwe chete kugadzira, kuchengeta, uye kuburitsa urume. Matestes ndiwo nzvimbo inogadzirwa urume netestosterone. Urume hunogadzirwa mumatestes hunozochengetwa kwenguva pfupi mu epididymis kuti hukure.
Panguva yekubuda kwembeu, mbeu yemurume inofamba kubva mu epididymis ichienda mu vas deferens kuenda ku ampulla, yozoenda ku duct inoburitsa manyoka. Prostate gland inobatsira pakuita izvi nekugadzira mvura yembeu, iyo inosanganiswa nembeu kuti igadzire urume. Mvura ye alkaline inogadzirwa neprostate gland inobatsira kuderedza acidity ye urethra ne vagina, zvichiita kuti mbeu yemurume irambe iripo. Saka, ma testes ne prostate gland zvinoshanda pamwe chete zvakanaka kuburikidza nekufamba kwembeu uye kusanganiswa kwemvura kuti zvitsigire kubereka.
Mubvunzo 4: Basa remuromo wechibereko nderei uye rinobatsira sei munhengo dzekubereka dzevakadzi?
Kukurukurirana:
Muromo wechibereko chikamu chepazasi chechibereko chinosanganisa chibereko nemukadzi. Muromo wechibereko une mabasa akawanda munhengo dzekubereka dzevakadzi. Munguva yekuenda kumwedzi, magadzirirwo uye kugara zvakanaka kwemukaka wechibereko zvinochinja, izvo zvinoita basa guru mukubatsira kana kudzivirira kupinda kwembeu muchibereko.
Munguva yekubuda kwembeu, manyoka emumuromo wechibereko anova matete uye ane alkaline yakawanda, zvichiita kuti zvive nyore kuti mbeu yemurume iende kuchibereko kunoberekeswa. Kusiyana neizvi, kunze kwehwindo rakaorera, manyoka emumuromo wechibereko anokora uye ane acid yakawanda, zvichitadzisa mbeu yemurume kupinda. Uyezve, muromo wechibereko unoshandawo sechidziviriro, uchidzivirira mabhakitiriya ane njodzi kuti asapinde muchibereko.
Munguva yekuzvitakura, muromo wechibereko unokora uye unofukidzwa nemadzihwa akakora, zvichidzivirira mwana ari kukura. Munguva yekusununguka, muromo wechibereko unokura, zvichiita kuti mwana aberekwe. Nemabasa awo akasiyana-siyana, muromo wechibereko chinhu chakakosha chakabatana nezvimwe zvinhu zviri muhurongwa hwekubereka.
Mubvunzo 5: Kurukurai hukama huripo pakati peguruva remuura neurethra munhengo dzekubereka dzevarume.
Kukurukurirana:
Babu remuuro chikamu chemukati memuuro chiri kutenderedza urethra yechirume uye chinoita basa mukuita kwekubuda kwembeu nekuburitsa mbeu. Chikamu ichi chinosanganisira matumbu anogadzira madzihwa, ayo anobatsira kunyorovesa urethra kuti mbeu yemurume ifambe zvakanaka panguva yekubuda kwembeu.
Urethra pachayo ichubhu inobatanidza dundira nenhengo dzekubereka nekunze kwemuviri, ichishanda kuburitsa weti nembeu. Panguva yekubuda kwembeu, sphincter yemukati inodzivirira weti kuti isapinde muurethra, uye girobhu reurethra rinopa mafuta echisikigo. Mafuta aya haangobatsiri chete kupfuura kwembeu asiwo anobatsira kuderedza kukuvara kwembeu kunokonzerwa nekukweshana.
Kushanda kwebhabhu remuuro neurethra munhengo dzekubereka dzevarume kunoratidza kubatana kwakanaka pakati pezvimiro zvemuviri nemabasa emuviri, izvo zvinoita kuti maitiro ekubereka afambe zvakanaka.
Mhedziso
Kunzwisisa kubatana kwenhengo dzakasiyana-siyana dziri mukati mehurongwa hwekubereka kunoita kuti tinzwisise kuti muviri wemunhu wakagadzirirwa sei basa rakaoma rekubereka. Kuburikidza nekubatanidza uye kushanda kwenhengo, hurongwa hwekubereka hunoratidza kushanda pamwe chete kwakaoma uye kwakabatana kwezvehupenyu. Nekunyatsoongorora kubatana uku, hatingowedzere kunzwisisa kwedu mashandiro emuviri chete asiwo tinovhura mukana wekuwana rubatsiro rwehutano rwunoshanda uye dzidzo yehutano.
