Mibvunzo Yemuenzaniso Inotsanangura Basa reSistimu Yekutenderera Kweropa Mukutakura Nekuchinjana Kwezvinhu
Sisitimu yeropa inoita basa guru muhupenyu hwezvinhu zvipenyu zvakaoma kunzwisisa, kunyanya vanhu nedzimwe mhuka. Inoshanda senzira huru yekufambisa zvinovaka muviri, magasi, mahormone, uye tsvina mumuviri wese. Kunzwisisa sisitimu yeropa kwakakosha kwete chete kubva pamaonero ehupenyu asiwo pakushandiswa kwekiriniki uye hutano. Chinyorwa chino chichaongorora nyaya iyi kuburikidza nemienzaniso yakati wandei yezvinetso zvinoratidza basa guru resisitimu yeropa.
Mubvunzo 1: Tsanangura kuti nzira yekufambisa ropa inotonga sei kutakurwa kweokisijeni mumuviri!
Kukurukurirana:
Sisitimu yeropa, inoumbwa nemoyo, mitsipa yeropa, neropa, ndiyo inogovera okisijeni kubva kumapapu kuenda kumasero ese mumuviri. Izvi zvinotanga mumapapu, uko okisijeni inofemerwa yopinda mualveoli. Pano, okisijeni inopararira nepa alveolar membrane yopinda mumapapu e capillaries. Okisijeni inobva yabatana ne hemoglobin iri mumasero matsvuku eropa uye inotakurwa nepamapapu kuenda kuruboshwe rwemoyo.
Mwoyo unopomba ropa iri rine okisijeni yakawanda kuburikidza neaorta uye mumuviri wese. Mushure mekunge masero emuviri ashandisa okisijeni kuti ashandise simba, ropa risina okisijeni rinodzokera kumoyo kuburikidza nevena cavae yepamusoro nepasi, uko rinopombwa kuenda kumapapu kuti ribvise carbon dioxide uye ritore okisijeni itsva. Kutenderera uku kunoenderera mberi nguva dzose, zvichiita kuti okisijeni iwanikwe zvakakwana kuti itsigire mashandiro emasero nenhengo.
Mubvunzo 2: Sistimu yeKutenderera Kweropa Inobatanidzwa Sei Mukutakurwa Kwezvinovaka Muviri Netsvina Yemetabolism?
Kukurukurirana:
Zvinovaka muviri zvinotorwa kubva muchikafu, zvakaita seglucose, amino acids, fatty acids, mavhitamini, nemaminerari, zvinopinda muura zvopinda muropa. Nzira yeropa inogovera zvinovaka muviri izvi mumuviri wese, kunhengo nematishu anodiwa pakukura, kugadziriswa, uye kugadzirwa kwesimba.
Masero paanoshandisa zvinovaka muviri neokisijeni, anogadzira zvinhu zvinovaka muviri zvinofanira kubviswa nekukurumidza kudzivirira huwandu hwechepfu. Sisitimu yeropa inotakura tsvina yakaita secarbon dioxide neurea kubva mumasero ichienda kunhengo dzinobudisa tsvina. Carbon dioxide inotakurwa kuenda kumapapu kuti ibviswe kuburikidza nekufema, ukuwo urea ichiendeswa kuitsvo kuti ibviswe muweti.
Mubvunzo 3: Kurukurai Basa reSistimu yeKutenderera Kweropa Mukugadzirisa Tembiricha yeMuviri!
Kukurukurirana:
Sisitimu yeropa inoita basa guru mukudzora tembiricha yemuviri, kana kuti thermoregulation. Kana tembiricha yemuviri yakwira, mitsipa yeropa iri pedyo neganda inokura, nzira inozivikanwa se vasodilation. Izvi zvinobvumira ropa rakawanda kuyerera pedyo neganda uye zvinowedzera kurasikirwa nekupisa kunzvimbo, zvichitonhodza muviri.
Kusiyana neizvi, kana tembiricha yekunze ichitonhora, mitsipa yeropa inodzikira, kana kuti vasoconstrict, izvo zvinoderedza kuyerera kweropa kuenda kuganda uye zvinochengetedza kupisa kwemuviri. Uyezve, kuyerera kweropa kuenda nekubva munhengo dzemukati dzakadai seuropi nechiropa kunogona kudzorwa kuitira kuti tembiricha ikwane yemakemikari.
Mubvunzo 4: Kuongorora Kukanganiswa Kwezvirwere zveSistimu yeKutenderera Kweropa Pahutano
Kukurukurirana:
Kukanganisika kwehurongwa hweropa kunogona kukonzera matambudziko akasiyana-siyana ehutano. Semuenzaniso, atherosclerosis chirwere apo plaque inoungana pamadziro etsinga, ichidzikisa uye ichideredza kuyerera kweropa. Izvi zvinogona kukonzera BP (BP yakakwira), kurwara nemoyo, kana sitiroko.
Pamusoro pezvo, kushaya simba kwemoyo, uko mwoyo usingakwanise kupomba ropa zvinobudirira, kunoita kuti pave nekudzikira kweokisijeni nezvinovaka muviri munyama, izvo zvinogona kukonzera kuneta, kuzvimba, uye kupererwa nemweya. Zvirwere zveropa zvakaita seanemia, iyo inoratidzwa nekuderera kwemasero matsvuku eropa kana hemoglobin shoma, zvinoderedzawo kuwanikwa kweokisijeni, zvichikonzera zviratidzo zvakaita sekuneta, dzungu, uye kusviba kweganda.
Mubvunzo 5: Tsananguro yeKudyidzana pakati peSistimu yeKutenderera Kweropa neMamwe Masisitimu Mumuviri
Kukurukurirana:
Sisitimu yeropa inoshanda pamwe chete nedzimwe sisitimu dzemuviri kuchengetedza homeostasis. Muenzaniso mukuru ndewekudyidzana kuripo pakati pemasisitimu eropa nekufema. Sezvambotaurwa, sisitimu yeropa inotakura kabhoni dhayokisaidhi kuenda kumapapu kuti ibudiswe.
Sisitimu yeropa inosanganawo nesisitimu yekugaya chikafu kuti igovere zvinovaka muviri uye inoshandawo nesisitimu yeropa kuti ifambise mahormone kubva kumagland kuenda kunhengo dzinoda kubatsirwa. Sisitimu yeropa inokoshawo kusisitimu yekudzivirira muviri; masero machena eropa anotenderera nemutsinga dzeropa kuti atsvage uye aparadze utachiona hunopinda mumuviri.
Mubvunzo 6: Kutenderera kweropa kunoenderana sei nezvinodiwa zvemuviri?
Kukurukurirana:
Muviri wemunhu nedzimwe mhuka dzakawanda dzinoratidza kuchinja kwakasiyana-siyana muhurongwa hweropa kuti dzipindure zvinodiwa zvakasiyana-siyana zvemuviri. Semuenzaniso, kana munhu achiita maekisesaizi, kudiwa kweokisijeni nekubvisa kabhoni dhayokisaidhi kunowedzera. Mwoyo unopindura nekuwedzera kuwanda uye simba rekudzikira kwemakumbo, nokudaro zvichiita kuti ropa riende kumhasuru dzinoshanda.
Zvimwe zvinogadziriswa zvinosanganisira kuwedzera kwehuwandu hwemasero matsvuku eropa muvanhu vanogara munzvimbo dzakakwirira, uko kushushikana kweokisijeni kwakaderera. Izvi zvinovavarira kuwedzera kugona kweropa kutakura okisijeni, nokudaro zvichiita kuti oxygen iwanikwe zvakakwana munyama dzemuviri pasinei nekuwanda kweokisijeni mumhepo.
Mhedziso
Sisitimu yeropa inodiwa zvikuru mukutonga nekufambisa zvinhu mumuviri wese. Kutakurwa kweokisijeni, zvinovaka muviri, uye marara emuviri zvakanaka ndiko kunokosha pakukura kwakanaka uye kushanda zvakanaka kwemuviri. Kunzwisisa basa resisitimu yeropa kwakakosha kuti nyanzvi dzezvehutano dzigadzire nzira dzakakodzera dzevanhu vane matambudziko emwoyo. Saka, kudzidza nezvesisitimu yeropa hakungobatsiri chete padzidzo yechikoro asiwo kune zvakunobatsira pakuchengetedza hutano hwakanaka.
