Isingeniso: Ingwane Enezinhliziyo Ezintathu
Ingwane yaziwa ngezici zayo eziyingqayizivele, kodwa enye yezinto ezithakazelisa kakhulu izinhliziyo zayo ezintathu. Ngokungafani nezilwane eziningi, ezinenhliziyo eyodwa noma ezimbili kuphela, ingwane inamaphampu amaningi azimele asebenza ndawonye ukuze agcine umzimba wayo usebenza. Lesi sihloko sizohlola i-anatomy kanye nomsebenzi wezinhliziyo zengwane, kanye nezinzuzo nomlando wokuziphendukela kwemvelo walesi simiso sezitho esihehayo.
I-Anatomy ye-Octopus: Ukubuka Kafushane
Ngaphambi kokuhlolisisa imininingwane yezinhliziyo ze-octopus, kubalulekile ukuqonda isimo somzimba wesilwane. Ama-octopus angama-cephalopods, ikilasi le-mollusk elihlanganisa ne-squid ne-cuttlefish. Zinomzimba othambile, onemisipha ohlukaniswe izingxenye ezimbili eziyinhloko: ikhanda nesigqoko. Ikhanda liqukethe amehlo, uqhwaku nezingalo ze-octopus, kuyilapho ingubo igcina izitho zangaphakathi, kuhlanganise nezinhliziyo.
Izinhliziyo Ezintathu Ze-Octopus: Isici Esiyingqayizivele
Ingwane inezinhliziyo ezintathu, ngayinye etholakala engxenyeni ehlukile yomzimba wayo. Izinhliziyo ezimbili ziyi-branchial hearts, enesibopho sokujikeleza igazi ngama-gill ukuze i-oxygen it. Inhliziyo yesithathu iyinhliziyo ehlelekile, empompa igazi elinomoya-mpilo kuwo wonke umzimba. Leli lungiselelo eliyingqayizivele lenhliziyo livumela ingwane ukuba igcine ukugeleza kwegazi elinomoya-mpilo njalo kuzo zonke izitho zayo, ngisho nalapho ihamba ngokushesha noma ishintsha umbala.
Umsebenzi Wezinhliziyo ze-Octopus: Okuyisisekelo
Izinhliziyo zengwane zisebenza ndawonye ukuhambisa igazi kuwo wonke umzimba walo, kodwa inhliziyo ngayinye inomsebenzi othile. Inhliziyo yokuqala inesibopho sokumpompa igazi eline-deoxygenated lisuka emzimbeni liye emathangeni, lapho lifakwe umoya-mpilo. Inhliziyo yesibili ibe isimpompa igazi elinomoya-mpilo liye kuwo wonke umzimba. Inhliziyo yesithathu isiza ukulawula umfutho wegazi futhi igcine ukugeleza kwegazi okuqinile.
Inhliziyo Yokuqala: Ukupompa Igazi Emzimbeni
Inhliziyo yokuqala, etholakala eduze kwekhanda le-octopus, inesibopho sokumpompa igazi eline-deoxygenated lisuka emzimbeni liyise ezindongeni. Le nhliziyo iyakwazi ukukhiqiza umfutho owanele wokuphusha igazi kuma-capillaries amancane kuma-gill, lapho kwenzeka khona ukushintshaniswa komoya-mpilo. Uma igazi selifakwe umoya-mpilo, lidlulela enhliziyweni yesibili ukuze lisatshalaliswe kuwo wonke umzimba.
Inhliziyo Yesibili: I-Oxygenation kanye Nokujikeleza
Inhliziyo yesibili isembathweni futhi inesibopho sokumpompa igazi eline-oxygen kuwo wonke umzimba. Le nhliziyo iyakwazi ukukhiqiza ingcindezi eyanele yokunqoba ukumelana nemithambo yegazi futhi ilethe umoya-mpilo nezakhi kuzo zonke izitho nezicubu.
Inhliziyo Yesithathu: Ukugcina Umfutho Wegazi Uzinzile
Inhliziyo yesithathu nayo itholakala ku-mantle futhi inesibopho sokulawula umfutho wegazi. Le nhliziyo ingakwazi ukulungisa izinga layo namandla okufinyela ukuze igcine ukugeleza kwegazi okuqinile, ngisho nalapho ingwane ishintsha umbala noma ihamba ngokushesha.
Izinzuzo Zokuba Nezinhliziyo Ezintathu
Izinhliziyo ezintathu ze-octopus zinikeza izinzuzo eziningana phezu kwezilwane ezinenhliziyo eyodwa noma ezimbili kuphela. Kokukodwa, amaphampu amaningi aqinisekisa ukuthi igazi eline-oxygen lihlala lilethwa kuzo zonke izitho, ngisho nangezikhathi zokusebenza okuphezulu. Ukwengeza, amaphampu azimele avumela i-octopus ukuthi ilawule ukugeleza kwegazi ezingxenyeni ezihlukene zomzimba, okubalulekile ekushintsheni umbala noma ukuthungwa.
Kungani Zonke Izilwane Zingenazo Izinhliziyo Eziningi?
Izinhliziyo eziningi azivamile ezilwaneni, njengoba zidinga inani elikhulu lamandla ukuze zigcinwe. Ezilwaneni eziningi, inhliziyo eyodwa noma ezimbili zanele ukumpompa igazi emzimbeni wonke. Kodwa-ke, ezilwaneni ezinamazinga aphezulu e-metabolic noma izinhlelo eziyinkimbinkimbi zokujikeleza kwegazi, izinhliziyo eziningi zinganikeza inzuzo yokuziphendukela kwemvelo.
Ukuvela Kwenhliziyo Ye-Octopus
Ukuvela kwezinhliziyo ezintathu ze-octopus kuseyisihloko socwaningo nenkulumo-mpikiswano. Abanye ososayensi bakholelwa ukuthi izinhliziyo zavela ngokuzimela kuma-cephalopods, kanti abanye basikisela ukuthi izici zokhokho eziye zalahleka kwezinye izimbungulu.
Ukubaluleka Kokuqonda I-Octopus Physiology
Ukuqonda i-anatomy kanye ne-physiology ye-octopus, kuhlanganise nezinhliziyo zayo ezintathu, kubalulekile ngezizathu ezihlukahlukene. Okokuqala, ingasisiza siqonde ukuvela kwezinhlelo zezitho eziyinkimbinkimbi nokuthi zinikeza izinzuzo ezilwaneni ezithile. Ukwengeza, ukufunda nge-octopus kunganikeza ukuqonda nge-physiology yomuntu nokuthi singazithuthukisa kanjani izindlela zokwelapha ezintsha zezifo zenhliziyo.
Isiphetho: Izimangaliso Zezinhliziyo Ezintathu Ze-Octopus
Izinhliziyo ezintathu zengwane zingesinye sezici eziningi ezithakazelisayo zalesi silwane esihlakaniphile nesivumelana nezimo. Ngokufunda i-anatomy kanye nokusebenza kwezinhliziyo ze-octopus, singathola ukuqonda okujulile kokuthi izinhlelo zezitho eziyinkimbinkimbi zisebenza kanjani nokuthi ziguquke kanjani ngokuhamba kwesikhathi. Ekugcineni, izimangaliso zezinhliziyo ezintathu zengwane zisikhumbuza ngokuhlukahluka okumangalisayo nobunkimbinkimbi bezinto eziphilayo emhlabeni wethu.
