Sexual nhengo yemhuka. Animal kubereka. The Kudeuka uye mhuka duku

Vakawanda vanofarira mhuka mamiriro ayo. Hazvina aripo pose chete pakona pose. Munyaya ino unogona kuwana ruzivo kwete chete pamusoro kupfuura guru uye zviduku fauna of, asi uzive kuti zvinhu kurara nhengo dzemhuka uye muitiro wokuberekana.

General ruzivo pamusoro pemhuka

Animals - ndivo vamiririri umambo zvipenyu. Ndivo chikuru chinhu kudzidza Zoologie. In masero mhuka chipo tsentrosfera. Chikonzero ichi vari kunzi eukaryotes. The zvinokosha mhuka zvinhu zvinotevera zvinogona kusanganisira:

• Food yakagadzirwa Organic zvinhu.
• Active kufamba.

Vazhinji vanodavira kuti mhuka umambo zvinosanganisira chete mhuka. maonero Izvi ndakanganisa. Kutaura zvazviri, mhuka zvinosanganisirawo hove, shiri, tumbuyu uye nevamwe vakawanda. Kare ichi umambo zvoutachiona kwaisanganisira uyewo tusingaoneki iyo vane sero rimwe chete. Zvino izwi "mhuka" hunongotaura zvipuka zvine masero akawanda zvinenge.

To musi, masayendisiti vanopfuura miriyoni imwe akarondedzera-siyana kwemarudzi ezvinhu mhuka. Pakutanga inogarwa nokuwanda arthropods. Nyanzvi dzinoti zvose mhuka umambo kunobva flagellated tusingaoneki. Vazhinji anozivikanwa mhando fauna of akazviratidza anenge mamiriyoni 500 apfuura. Zvisinei, masayendisiti akawanda vanodavira kuti zvakaitika ipapa.
Mhuka dzose Tidzidze nezvimwe zvinhu zvipenyu. Chikonzero ichi, vari heterotrophic. fauna of All of nzira romugove vari akakamurwa inotevera mapoka:

• Herbivores.
• Mbeswa.
• Tupukanana.
• Omnivores.

mhuka dzose dziri kwakasiyana mumwe muupenyu, nzira zvokudya uye kubereka. Chikonzero ichi kuti vamiririri vose mhuka vakabatwa voga.

Nemamiriro dzokubereka nadzo dziri makwai nembudzi. Zvakakurukurwa dzokubereka nadzo varume

Dzokubereka nadzo nhengo iri chokuita nokushanda kwenhengo muviri wose. chinangwa chavo chikuru - ndiye kuenderera mhando.

The sikarudzi makwai nhongo nembudzi zvinosanganisira:

• Testes.
• Seed waya netambo.
• Sex mumasero.
• Scrotum.
• Genitourinary gwara.
• Yekuberekesa.

The nhengo dzokubereka nadzo mbudzi namakwai kubereka milliliters shoma urume.

Testis - Nde nhengo ngakuite pamuviri basa. Ndicho paumbwe dzisingaoneki kukura. Uyewo kucherechedza ndechokuti testis unobereka makono mahormone. At gondohwe muviri ichi ane uremu 300 magiramu uye mbudzi nehafu.

Testis iri denderedzwa mu chimiro. Kurutivi chiri manda. Pane vakura dzisingaoneki kwenguva yakawanda nguva.

Testis iri muna scrotum. In makwai nhongo nembudzi riri pakati pazvidya. The tembiricha iri scrotum dererei zvikuru kupfuura dzimwe nhengo dzomuviri. chinhu ichi ndiyo akanakira pokumuka zvinoumba urume.

scrotal neganda kenza. pamusoro rinofukidzwa romusoro. Pasi paganda romuviri chinhu jira anonzwisisa. Anoumba chipingamupinyi uye testis rinokamukana muzvikamu zviviri.

The chikuru kushanda genitourinary ino ndiyo voga kubva muviri urume weti uye. Muviri kuchibva tunica muscularis mucosa uye, uyewo cancellous rukoko.

Features dzokubereka nadzo makwai munhukadzi uye nembudzi

mhuka dzakasiyana mhando nhengo dzakavandika zvinosiyana zvikuru pakati pavo. Chikonzero ichi kuti mumwe boka fauna of vanofanira kunzi yoga.
By pabonde nhengo dzokubereka nadzo zviduku nyanga mombe zvechikadzi dzinosanganisira:

• Ovaries.
• Fallopian chubhu.
• Vagina.
• Dumbu.
• External nhengo dzokubereka nadzo.

Ovaries - simba denderedzwa. Ivo dziri munzvimbo dzakaderera seri nzvimbo. Zviri mumuviri uyu akaumba mukadzi bonde masero uye mahormone. Zvinenge penyika yose ovaries rinosanganisira germinal epithelium. Pasi ndicho follicular nharaunda umo zai aumbwa, uye follicle.

Fallopian sepombi - rakamanikana chubhu unobatanidza dumbu. Kureba kunosiyana-siyana pakati 12 uye 16 masendimita. Zviri pano kuti muchangosangana kunoitika.
Dumbu - muviri umo kukura mudumbu. Panguva basa rikurumidze nayo achisunda mwana kunze kuburikidza pakuberekwa Canal. The dumbu ine nyanga, muviri uye mutsipa.

Kubereka mombe. Muchangosangana uye pamuviri

Kubereka - inofanira kuti tinoberekwa dzavamwe vapenyu muviri. Chinangwa chikuru kubereka - ndiwo kubereka dzavo mutsa kuberekana. Propagation yemhuka vertebrate imhaka kubatana vaviri masero - urume uye ovum. inotungamirwa wavo zvinogoneka chete pashure pakuyaruka. In makwai nembudzi toreva 7-8 mwedzi upenyu. Chipotera zvingaitika paya. It zvinoenderana zvinoitwa rudzi uye mumuviri ezvinhu.
Mugore, makwai nembudzi vakabata zvinogara akawanda pabonde. Mumwe nomumwe wavo anotora avhareji vhiki mbiri mazuva 20. Panguva yose kutenderera kuitika mumuviri akasiyana-siyana kuchinja, kureva kugadzirira pakusangana uye pamuviri.

Kana mushure muchangosangana pamuviri kumboitika, ipapo nenhunzvi zviduku ruminants kunoitika vakadengezera pachikuva. The bonde nhengo emhuka havachakwanisi kuumba zai upenyu 8-10 gore.

Kana wekusangana mumuviri gwai munhukadzi uye nembudzi -wedzera muviri. Pamuviri anotora avhareji pamusoro 5 months.

Tsinga harinzwi vari nhengo dzakavandika wemhuka umambo

The bonde nhengo emhuka kukonzera gakava zvikuru pakati zoologists. Kuburikidza navo muri harinzwi tsinga. Vamwe zoologists vanodavira kuti yakazvimirira tsinga centre aripo ari munhukadzi sikarudzi. Zvisinei, kutsvakurudza zvimwe nyanzvi regai kuzosimbisa ichi.

Dumbu inosanganisira yokuwanda harinzwi tsinga zvine chokuita nedzimwe nhengo inokosha. Izvi zvinobatsira kutsanangura panowanikwa marwadzo anopona.

Dzokubereka nadzo mune mabhiza. muchangosangana Features

Kubereka uye pabonde bhiza miviri vane akawanda zvinhu. Izvi uye zvakawanda unogona kuwana nyaya yedu.

By mukono kwokunze sikarudzi zvinosanganisira yemukomana uye testes. The munhukadzi nhengo dzokubereka nadzo dzinosanganisira ovaries, dumbu, nyinyo uye vulva. Nguva apo Bhiza vagadzirira pakusangana inonzi kundovhima. Rinotora kubva 3 kusvika 10 mazuva. Pashure pakuguma kuvhima nguva nehadzi havagoni kubereka hwepedyo mukono pamberi mumwedzi. Kazhinji izvi kunoitika muzhizha kana matsutso mwaka. Pakadaro, kana pamuviri kumboitika, ari kuvhima nguva inodzokororwa.
Kana ruminant mabhiza vanowanzoshandisa chakagadzirwa insemination. Izvi zvinobvumira kuti kubvisa matambudziko zvokufambisa uye kusada kuti vakadzi ruchikonzera. A pamuviri anogona chete hwokugadza murapi wemhuka. Kuti aite izvi, iye anoongorora dumbu kuburikidza mugaranhoko. Sikarudzi chemhuka panguva yepamuviri kuzvimba zvinooneka.

Pamuviri kunogara kwemwedzi 11. Ya iyi kunoenderana zvokudya, kugutsikana uye zera hwemhuka. Ya zvounzenza kutenderera ari vakadzi ndiyo 20 kusvika 24 mazuva.

Nhengo dzokubereka nadzo mune tsoko. Kusiyana

Vazhinji vanodavira kuti murume hwakabva netsoko. Izvi inodzivisa zoologists. Izvi imhaka Misiyano iri marongerwo uye zviri rudzi. Chakatishamisa mukono tsoko vanokwanisa kuziva kana munhukadzi inopfuura nguva ovulation. Hazvina chakavanzika vanhu vane chikamu ichi iripo. tsoko dzakasiyana uye kushaya kubereka. Nyaya iyi aripo chete rimwe marudzi.

Sikarudzi tsoko vavo ezvirevo vaivawo yakasiyana yevanhu. Nhunzvi havana hymen. Male pabonde nhengo kunosanganisira kwayo maumbirwo mapfupa shwashwa.

Kusiyanisa hadzi kubva hono chihwenga

Kazhinji vanoda mhuka kushamisika sei kusiyanisa varume mukadzi chihwenga. kuzviita pachako zvisingabviri pakutanga kuaona. Munyaya ino, unogona kudzidza pamusoro nyaya dzebonde kutsunga.
