I-Anatomy yeebhokhwe: Ukuphonononga injongo yeendlebe zabo ezinkulu

Intshayelelo: IAnatomy yeebhokhwe

Iibhokhwe zizilwanyana ezanyisayo ezikusapho lwe Bovidae. Zitya utyani kwaye zigcinwe ngezizathu ezahlukeneyo ezifana nobisi, inyama, kunye noboya. I-anatomy yeebhokhwe sisihloko esinomdla, ngakumbi xa sifika ezindlebeni zabo. Iindlebe zeebhokhwe zinkulu kwaye zine-floppy; zezinye zezona mpawu zibalaseleyo zesilwanyana. Kodwa kutheni iibhokhwe zineendlebe ezinkulu kangaka?

Injongo yokuzivelela kweendlebe ezinkulu

Iibhokhwe, njengezinye izilwanyana, ziye zavela ukuze ziqhelane nendawo yazo. Iindlebe zazo ezinkulu ziye zaphuhliswa ngenxa yokufuna kwazo ukuphila endle. Iibhokhwe zizilwanyana ezizixhoba, kwaye iindlebe zazo ezinkulu zinceda ukuba zibone nayiphi na ingozi enokubakho. Iindlebe zabo zisebenza njenge radar, zicholachola ezona zandi zincinci, ezinokuthi zibe lirhamncwa elisondelayo. Ukuba zinkulu iindlebe, ngcono uluhlu lokuva. Oku kunika iibhokhwe ithuba elihle endle, njengoko ziyakwazi ukubona izilwanyana ezizingela kude kwaye zikwazi ukuphepha.

Ubume beendlebe zebhokhwe

Iindlebe zeebhokhwe zenziwe ngamalungu amathathu: indlebe engaphandle, indlebe ephakathi, kunye nendlebe yangaphakathi. Indlebe engaphandle yinxalenye ebonakalayo yendlebe kwaye yenziwe nge-cartilage egqunywe lusu. Indlebe ephakathi iqulethe i-eardrum, amathambo amancinci amathathu, kunye ne-Eustachian tube. Indlebe yangaphakathi inoxanduva lokulinganisela kwaye iqulethe i-cochlea, ejongene nokuva. Indlela indlebe yebhokhwe eyakhiwe ngayo ivumela ukuba ive izandi kumgama omde.

Indima yeNdlela yeNdlebe kunye neGubu leNdlebe

Umjelo wendlebe ngumbhobho odibanisa indlebe yangaphandle kwindlebe ephakathi. Inoxanduva lokuhambisa amaza esandi kwi-eardrum. Xa amaza esandi engena kumjelo wendlebe, enza ukuba umbhobho wendlebe ungcangcazele. Emva koko indlebe idlulisela ezi ntshukumo kumathambo akumbindi wendlebe, aze wona athumele imiqondiso kumbindi wendlebe.

Isandi sasekhaya kwiibhokhwe

Iibhokhwe ziyakwazi ukufumana izandi ngokuchanekileyo. Iindlebe zazo ezinkulu zizinceda ukuba ziphakamise izandi ezivela kumacala ahlukeneyo, nto leyo ezenza zikwazi ukuqonda icala esiya ngakulo isandi. Oku kubalulekile xa kuziwa ekubhaqweni amarhamncwa. Iibhokhwe ziyakwazi ukubona icala lerhamncwa kwaye zikwazi ukuliphepha.

Uvakalelo Lweendlebe Zebhokhwe

Iindlebe zeebhokhwe zibukhali kakhulu. Ziyakwazi ukuva izandi eziphakamileyo kakhulu ukuba abantu bangaziva. Iibhokhwe zisenakho ukucholaza izandi kumgama omde. Obu buntununtunu bubalulekile ekuphileni kwazo endle.

Iindlebe njenge-Heat Regulators

Iindlebe zeebhokhwe zikwadlala indima ekulawuleni ubushushu bomzimba wazo. Xa kushushu, imithambo yegazi ezindlebeni zabo iyavuleka, nto leyo evumela ubushushu buphume emizimbeni yabo. Xa kubanda, imithambo yegazi iyaqina, inceda ukugcina ubushushu.

Iindlebe njengeMiqondiso yoBundlongondlongo

Iibhokhwe nazo zisebenzisa iindlebe zazo njengemiqondiso yohlaselo. Xa ibhokhwe inomsindo okanye inoburhalarhume, iya kuthoba iindlebe zayo entlokweni yayo. Esi sisilumkiso kwezinye izilwanyana ukuba zingahambi.

Ubudlelwane phakathi kweendlebe neempondo

Iimpondo zeebhokhwe zikwahlobene neendlebe zazo. Iimpondo zisetyenziselwa ukuzikhusela, kwaye iibhokhwe zisebenzisa iindlebe zazo ukubona ingozi enokwenzeka. Oku kubavumela ukuba basebenzise iimpondo zabo ngokufanelekileyo ukuze bazikhusele.

Iindlebe zebhokhwe kunye nokufunyanwa kwe-Predator

Iindlebe ezinkulu zeebhokhwe zibalulekile ekuboneni amarhamncwa. Ziyakwazi ukuva amarhamncwa kumgama omde, oko kubanika ixesha elininzi lokuziphepha. Oku kubaluleke ngakumbi endle, apho iibhokhwe zingamaxhoba.

Ukubaluleka kweendlebe ezinkulu kwiibhokhwe zaseKhaya

Iindlebe ezinkulu zisabalulekile kwiibhokhwe ezifuywayo. Iibhokhwe ezifuywayo zisenethuku elifanayo neleentaka zazo zasendle, kwaye iindlebe zazo ezinkulu zinceda ukuba zibone nayiphi na ingozi enokubakho. Oku kubalulekile kukhuseleko kunye nokuphila kakuhle.

Isiphelo: Ukubaluleka Kweendlebe Zebhokhwe

Iindlebe ezinkulu zebhokhwe luphawu olwahlulayo esi silwanyana. Zidlala indima ebalulekileyo ekusindeni kwesilwanyana endle kwaye zisabalulekile kwiibhokhwe ezifuywayo. Uvakalelo lweendlebe zabo, ukukwazi kwabo ukuva isandi sasekhaya, kunye nokusetyenziswa kwazo njengezilawuli zobushushu kunye nemiqondiso yohlaselo zonke zibalulekile ukuze ziphile. Iindlebe zeebhokhwe zibubungqina bokuvela kwesilwanyana kunye nokuqhelana nendalo yazo.
