The kweropa maitiro kwevanhu uye pakarepo ropa

Wednesday, kufanana ropa, paiva kare, panguva pakuonekwa wokutanga zvipuka zvine masero akawanda zvinenge. Zvinonzwisiswa kuti zvinenge chete-celled vakadaro haana kudiwa. Asi iye akapa mhando iyi shanduka achapesana mberi - unicellular aifanira kumirira kusvikira rinotevera kudya ichava, asi masero ezvinhu zvipenyu zvakawanda zvakaoma zvokudya zvakawanda stably. Kunyange zvinomera rakafanana background. Asi, nyaya ino ichataura kweropa womunhu hurongwa.

Vakasiyana-siyana anoitwa kuti mvura dzvuku mumuviri. Complex uye kweropa hurongwa. Ropa rinotakura dzinenge 6 mabasa.

1. It "anodya" masero pamwe muviri.
2. Anovanunura kubva tsvina.
3. Zvematongerwo thermoregulation, kupa zvakanakisisa ezvinhu.
4. Kupararira nomuviri regulators - mahormone.
5. Munyaya masoja pakaziviswa muviri nokukurumidza kupinda "zvakaipa".
6. It inotsigira Kuronga chenguva womukati kwezvakatipoteredza.

masero eropa dzakafukurwa chete muzana remakore rechi18 kubudikidza maikorosikopu kuvamba. Asi pane imwe chinoumba ropa - plasma, nemvura chikamu chake. Zvisinei, yeplasma ichiri kanoverengeka zvakawanda viscous pane mvura, sezvo rine mapurotini. Uye vachiri mupiro zvikuru kuti viscosity ropa akasuma erythrocytes. Kana tikatambura kubva kupera muviri, kuti richikora ropa (ichi zvinoitika kana kunyanyisa vangadikitira uye manyoka).

Vazhinji masero matsvuku zvose ropa, zvavanokupai ruvara. Also ririmo, uye murindi njodzi kudzivirira zvirwere - lymphocytes, uye maplatelet zvakawanda kuti usarega ropa kuyerera zvachose kuburikidza ronda diki. Hazvisi zvose pamusoro ropa, asi isu vanofarira yose kweropa hurongwa munhu rose, handizvo here?

Unosanganisira, kunze ropa, kunyange mwoyo uye ropa midziyo. Kazhinji pamwe kweropa uye nhengo dzinobudisa gadziriro ichaongororwa, nokuti node kuti ropa chaizvo chaizvo zvakabatana. Asi ari papepa iri, isu funga chete nemamiriro kweropa hurongwa.

Heart - zvakaoma chaizvo kuti noruoko akaronga aine mashandiro vasingatungamirirwi murau, asi pfungwa iyi mvumo kwenguva yakareba. Healthy mwoyo ine mbiri atria maviri ventricles. The chikuru Chikamu mwoyo - ari myocardium - ine yayo ropa rive. Regurgitation ari chakaipa mwoyo hazvibviri nokuti chinokosha nemamiriro mwoyo vharuvhu. Kana iwe kusunda mukova, iyo inotanga panheyo "pamusoro", iwe haimbofi mukamuri shure pamukova. The chete mamiriro ezvinhu ari ropa, asi zvinonzi "kudhonza musuo," kusiyana vakonewe. Human kweropa maitiro akagadzirirwa zvakakwana.

Achishandisa tsinga ropa kubva mumwoyo kuburikidza mutsinga - anouya kwaari. In iri systemic riparadzirwe (kubva kuruboshwe ventricle kusvika mapazi uye shure kurudyi atrium) oxygen-vapfumi arteries ropa, inopenya tsvuku. Mune mutsinga ose denderedzwa iri murima, izere carbon dioxide. Mudenderedzwa diki (kubva kurudyi ventricle kuti mapapu, uye kwavari kuruboshwe atrium) - iri zvinopesana.

Ose mvura ine kweropa hurongwa, 80% kubva tsinga. Pakati arteries uye mutsinga dziri vazhinji vezvikwata microscopically diki - rirambe richibvira. The arteries pamusoro denderedzwa guru ropa kuenda nyore - zvikuru ichangopfuura yava kuwedzera kubva pamwoyo. Asi ari mutsinga rakawanda zvakaoma - tichadzoka, kazhinji pamusoro giravhiti, ropa riri kusandudzirwa chaiwo mavharuvhu. Uye kubatsira mavharuvhu izvi zvakajairika skeletal tsandanyama. Saka, kudzivisa dziine tsvina, dzisingatarisiki varicose mutsinga pamusoro makumbo, unofanira kugara kuita chero mutambo, raisanganisira rutsoka. Nekuti tsandanyama makumbo enyu kubatsira ropa hwokukurira.

Sezvaunogona kuona, kweropa vanhu hurongwa anobvumira zvose zvakawanda mashandiro ropa, uye nokudaro kudzivirira zvirwere zvinofanira kugadziriswa kubva pauduku. Nokuti utano munhu kudya zvakanaka uye kuva mumuviri kushingaira svikiro zvakakwana.
