Kunzwisisa Maumbirwo uye Mashandiro eZvipfuyo
Kunzwisisa maumbirwo emhuka nemuviri wayo ihwaro hwakakosha hwekurimwa kwemhuka dzemazuva ano. Anatomy inodzidza maumbirwo emuviri nehurongwa hwenhengo, ukuwo physiology ichiongorora mashandiro anoita nhengo idzi nemaitiro ayo kuita mabasa ehupenyu. Ruzivo urwu runokosha pakuwedzera kubereka, kuchengetedza hutano hwemhuka, kudzivirira zvirwere, uye kuona kuti mhuka dzinogara zvakanaka. Mukuita, kunzwisisa maumbirwo emhuka nemuviri wayo kunobatsira varimi nevashandi vehunyanzvi kuita sarudzo dzine ruzivo maererano nechikafu, kutarisira dzimba, kubereka, uye kunyange kutarisira zvipfuwo zvinorwara.
Kunzwisisa Maumbirwo emuviri nePhysiology
Magadzirirwo emuviri wemhuka anosanganisira chimiro nenzvimbo yenhengo dzemuviri, kubva mudumbu, kufema, kufamba kweropa, kusvika pakubereka. Magadzirirwo emuviri anogona kukamurwa kuita macroscopic anatomy (zvinoonekwa nemaziso asina kusimba, zvakaita semapfupa, tsandanyama, uye nhengo) uye ma microscopic anatomy (senge matishu nemasero).
Panguva iyi, physiology inodzidza mashandiro enhengo idzi. Semuenzaniso, kuti kuviriswa kunoitika sei mudumbu remombe, kuti mapapu anochinjana sei magasi, kana kuti mahormone anotonga sei kutenderera kwe estrus mumbudzi nemombe. Maumbirwo emuviri ne physiology zvakabatana: maumbirwo akasiyana anosarudza mabasa akasiyana.
Masisitimu eSkeletal neTsvasuru: Rutsigiro uye Kufamba
Sisitimu yemapfupa muzvipfuyo inoshanda sekutsigira muviri, kudzivirira nhengo dzinokosha, uye kubatana kwetsandanyama. Musana unodzivirira musana, mbabvu dzinodzivirira moyo nemapapu, uye mapfupa emakumbo anoita basa guru mukufamba uye kugona kwezvipfuyo kumira kwenguva refu.
Tsandanyama inhengo dzinoshanda dzekufamba dzinoshanda pamwe chete nehurongwa hwemapfupa. Zvipfuyo zvinorerwa kuti zvigadzirwe nyama, zvakaita semombe dzemombe, makwai, nehuku dzenyama, zvinotsamira zvakanyanya pakukura kwetsandanyama. Kukura kwetsandanyama kunokonzerwa nezvinhu zvakaita semajini, kudya (kunyanya mapuroteni nesimba), uye kushanda. Kuneta, kukuvara, kana matambudziko emakumbo zvinogona kuderedza kushanda zvakanaka kwemhuka nekuti zvipfuwo hazvikwanise kufamba zvakanaka, zvinonetseka kudya, uye zvinogona kushushikana.
Sisitimu Yekugaya Zvokudya: Chinhu Chinokosha Pakubatsira Kudya Zvakakwana
Sisitimu yekugaya chikafu ndiyo inonyanya kukosha pakugadzirwa kwezvipfuyo nekuti inokanganisa zvakananga kushandiswa kwechikafu. Zvipfuyo zvinogona kupatsanurwa muzvikamu zviviri: mhuka dzinodya nyama dzinochera nedzisingadye nyama.
Mumhuka dzinodya nyama dzakadai semombe, nyati, mbudzi, nemakwai, dumbu rine zvikamu zvina: rumen, reticulum, omasum, uye abomasum. Rumen inoshanda se "fermenter" huru apo tupukanana (mabhakitiriya neprotozoa) tinopwanya shinda dzakakora se cellulose kuita volatile fatty acids, iyo inoshanda senzvimbo huru yesimba. Reticulum inobatsira mukusanganiswa nekuumbwa kwebolus kuti iwedzere kugaya (kuruma). Omasum inonwisa mvura nemaminerari, nepo abomasum iri dumbu chairo, richigadzira ma enzymes ekugaya.
Mhuka dzisingadye nyama dzakadai senguruve nehuku dzine matumbu akareruka. Huku dzine goho rekuchengetedza chikafu kwenguva pfupi, prontriculus yekugaya matumbu, uye gizzard yekukuya chikafu. Nekuti hadzina nzira yekuvirisa rumen, mhuka dzisingadye nyama dzinowanzoda chikafu chine hutano huri nyore kugaya.
Kunzwisisa mashandiro ekugaya chikafu kunobatsira varimi kugadzirisa kudya kwavo kuti kuenderane nezvavanoda. Kusaenzana kwekudya kunogona kukonzera matambudziko akadai sekuzvimba kwemhuka dzinodya nyama, manyoka mumhuru, kana kudzikira kwekugadzirwa kwemazai muhuku.
Sisitimu Yekufema: Kupa Okisijeni Kwemetabolism
Sisitimu yekufema inoshanda kuti itore okisijeni uye ibudise kabhoni dhayokisaidhi. Okisijeni inodiwa kuti mashandiro emuviri agadzire simba. Mumombe, mbudzi, nemakwai, mhepo inopinda nemumhino, pahuro, padundundu, patrachea, pabronchi, uye paalveoli mumapapu. Kuchinjana kwemagasi kunoitika mualveoli, uye okisijeni inotakurwa neropa kuenda kunhengo dzemuviri.
Mamiriro ekunze ane hunyoro, mhepo isina kufefetera zvakanaka, uye vanhu vakawanda vanogona kuwedzera njodzi yezvirwere zvekufema zvakaita sepneumonia. Panyaya yemuviri, zvipfuwo zvinoshaya simba rekufema zvinowedzera mwero wekufema kuti zvibatsire kutonhora, asi izvi zvinogona kuderedza kudya uye kubereka. Nokudaro, mhepo inofefetera, mvura, uye mumvuri zvakakosha kuti kufema kushande zvakanaka.
Sisitimu Yekutenderera Kweropa: Kutakurwa Kwezvinovaka Muviri Uye Kudzivirira Muviri
Mwoyo unopomba ropa kuti riparadzire okisijeni, zvinovaka muviri, nemahormone, pamwe nekubvisa tsvina yemuropa. Sisitimu yeropa inoumbwa nemoyo, mitsipa yeropa, neropa pacharo. Ropa rinoitawo basa guru mukudzivirira muviri kuburikidza nemasero machena eropa anorwisa hutachiona.
Zvirwere zveropa zvinogona kuva nemigumisiro yakakura, yakadai sekushaya ropa nekuda kwekushomeka kwesimbi kana tupukanana tweropa, izvo zvinogona kukonzera kushaya simba uye kusakura zvakanaka kwezvipfuyo. Panguva imwe chete, hutachiona hwemuviri hunogona kuwedzera tembiricha yemuviri uye kurova kwemoyo. Kuongorora kuri nyore kwakadai sekutarisa ruvara rwe retina, kuyera tembiricha, uye kuongorora kurova kwemoyo kunogona kubatsira kuona hutano hwezvipfuyo nekukurumidza.
Sisitimu Yetsinga Nepfungwa: Zvinodzora Mhinduro uye Maitiro
Sisitimu yetsinga inodzora kufamba zvakanaka, mhinduro dzezvakatipoteredza, uye mashandiro enhengo dzemukati. Uropi nemusana ndizvo zvinonyanya kukosha, nepo sisitimu yetsinga yekunze ichibatanidza nzvimbo idzi kunhengo netsandanyama. Pfungwa dzakadai sekuona, kunhuwidza, kunzwa, uye kubata dzinoita basa guru mukuita kudya, kuziva njodzi, uye kudyidzana nevamwe.
Panyaya yemuviri, kushushikana kwenguva refu—semuenzaniso, kubva mukubatwa zvisina kunaka, kutakurwa zvisina kunaka, kana nzvimbo dzakanyanya kuipa—kunogona kumutsa mahormone ekushushikana akadai se cortisol. Mhedzisiro yacho inogona kusanganisira kudzikira kwechido chekudya, matambudziko ekubereka, uye kudzikira kwesimba rekudzivirira muviri. Nokudaro, nzira yekuchengetedza mhuka haisi nyaya yetsika chete, asiwo ine chekuita zvakananga nemuviri uye kubereka.
Sisitimu Yekubereka: Hwaro hweKugadzirwa Kunogara Kwenguva Refu
Sisitimu yekubereka ndiyo kiyi yekubereka nekugadzira mukaka nenyama. Muvakadzi, nhengo huru dzekubereka dzinosanganisira maovari, maoviducts, chibereko, uye vagina. Maovari anoburitsa mazai nemahormone akadai seestrogen neprogesterone, izvo zvinodzora kutenderera kwe estrus (kupisa). Muvarume, matestes anoburitsa urume nehormone ye testosterone.
Kunzwisisa mashandiro ekubereka kunobatsira pakuona estrus, nguva yekuberekesa mwana, kutarisira pamuviri, uye kupa rubatsiro rwekurapa mushure mekusununguka. Matambudziko akadai se anestrus (kushaya estrus), placenta yakachengetwa, kana hutachiona hwechibereko zvinogona kuderedza huwandu hwepamuviri uye kuwedzera kurasikirwa. Kudya kunovaka muviri, mamiriro emuviri (huwandu hwemamiriro emuviri), uye hutano hwese zvinopesvedzera zvakanyanya kubudirira kwekubereka.
Sisitimu yeEndocrine: Mutongi weHormone uye Metabolism
Sisitimu yeendocrine inogadzira mahormone anodzora kukura, kugadzirwa kwemukaka, kubereka, uye kushandiswa kwemuviri. Mahormone akakosha anosanganisira pituitary, thyroid, pancreas, uye adrenal glands. Semuenzaniso, hormone inonzi insulin inobva mupancreas inodzora huwandu hweshuga muropa, ukuwo mahormone ethyroid achibatsira mukushandiswa kwemuviri.
Mahormone eprolactin neoxytocin akakosha pakugadzirwa kwemukaka. Prolactin inotsigira kugadzirwa kwemukaka, ukuwo oxytocin ichibatsira kubuda kwemukaka panguva yekukama. Mombe dzine dambudziko remukaka dzinogona kudzivirira kuburitswa kweoxytocin, zvichikonzera kudzikira kwekugadzirwa kwemukaka. Nekunzwisisa mashandiro aya emuviri, varimi vanogona kuvandudza nzira dzekukama mukaka, kuchengetedza runyararo, uye kuderedza kushushikana mumombe dzavo.
Penutup
Kunzwisisa hunhu hwemhuka uye mashandiro emuviri wayo kunopa hwaro hwakasimba hwekuwedzera kugona kwekugadzira uye kuchengetedza hutano hwemhuka. Hurongwa hwese huri mumuviri—hwekugaya chikafu, hwekufema, hweropa, hwetsinga, hwekubereka, uye hwema endocrine—hwakabatana uye hunotungamirirwa nezvinhu zvakaita sekudya, nharaunda, manejimendi, uye kugara zvakanaka kwemhuka. Kana munhu akanzwisisa zviri nani chimiro nekushanda kwemhuka, ndipo panogona kushandiswa matanho ekudzivirira nekurapa akakodzera. Izvi zvinoita kuti kurima kwemhuka kuve nezvibereko zvakawanda, kugare kwenguva refu, uye zvichienderana nepfungwa dzehutano hwemhuka.
