pulmonary leeg
Ntxiv mus, cov hlab ntsha tuaj yeem nqa cov ntshav deoxygenated piav qhia?
Cov hlab ntsha ua ib feem ntawm lub circulatory system. Arteries nqa oxygenated ntshav deb ntawm lub plawv mus rau cov ntaub so ntswg, tsuas yog pulmonary cov hlab ntsha , uas nqa ntshav rau lub ntsws rau oxygenation (feem ntau yog cov leeg nqa cov ntshav deoxygenated rau lub plawv tab sis cov hlab ntsws nqa oxygenated ntshav ib yam).
Ib yam nkaus, cov ntshav deoxygenated nkag rau hauv plawv qhov twg? Ntshav nkag mus rau hauv plawv los ntawm ob txoj hlab ntshav loj - tom qab (qis dua) thiab sab xub ntiag (siab dua) vena cava - nqa cov ntshav deoxygenated los ntawm lub cev mus rau hauv txoj cai atrium . Ntshav ntws los ntawm txoj cai atrium rau hauv txoj cai ventricle los ntawm tricuspid valve.
Ib yam li ib tus yuav nug, cov ntshav tau oxygen nyob hauv lub ntsws li cas?
Ntshav nkag mus rau sab xis atrium thiab hla los ntawm txoj cai ventricle. Lub ventricle sab xis tso lub ntshav mus rau lub ntsws qhov twg nws ua oxygenated . Cov oxygenated ntshav yog coj rov los rau hauv plawv los ntawm ntsws cov leeg uas nkag mus rau sab laug atrium.
Cov hlab ntsha puas tuaj yeem nqa cov ntshav deoxygenated thiab yog vim li cas?
Cov pulmonary cov hlab ntsha nqa cov ntshav deoxygenated Los ntawm txoj cai ventricle mus rau alveolar capillaries ntawm lub ntsws kom tshem tawm carbon dioxide thiab nqa oxygen. Cov no yog cov xwb cov hlab ntsha uas nqa cov ntshav deoxygenated , thiab raug txiav txim siab cov hlab ntsha vim lawv nqa ntshav deb ntawm lub plawv.

Cov hlab ntsha twg nqa cov ntshav mus thiab los ntawm lub ntsws?
Hauv lub ntsws, cov hlab ntsws (hauv xiav) nqa cov ntshav tsis muaj ntshav los ntawm lub plawv mus rau hauv lub ntsws. Thoob plaws hauv lub cev, cov hlab ntsha (liab) xa cov ntshav oxygenated thiab cov as-ham rau tag nrho lub cev nqaij daim tawv, thiab cov leeg ntshav (hauv xiav) xa cov ntshav tsis zoo rov qab los rau lub plawv
Puas yog Neuroglia tsim cov hlab ntsha hauv cov hlab ntsha hauv nruab nrab cov hlab ntsha?
Muaj plaub hom neuroglia pom nyob hauv nruab nrab lub paj hlwb: Astrocytes - tswj cov ntshav lub hlwb teeb meem thiab khaws cov tshuaj ib puag ncig los ntawm kev siv cov ions rov qab thiab cov tshuaj xa xov mus rau lub cev. Oligodendrocytes - myelinate axons nyob rau hauv lub hauv nruab nrab lub paj hlwb thiab muab tag nrho cov txheej txheem txheej txheem
Puas yog tag nrho cov hlab ntsha nqa cov ntshav oxygenated thiab cov leeg nqa cov ntshav deoxygenated?
Cov hlab ntsha ua ib feem ntawm lub circulatory system. Cov hlab ntsha nqa cov ntshav oxygenated tawm ntawm lub plawv mus rau cov ntaub so ntswg, tshwj tsis yog cov hlab ntshav hauv lub ntsws, uas nqa ntshav mus rau lub ntsws rau cov pa oxygen (feem ntau cov leeg ntshav nqa cov ntshav deoxygenated mus rau lub plawv tab sis cov leeg hauv ntsws nqa cov ntshav oxygenated ib yam)
Cov npe ntawm cov hlab ntsha uas nqa cov ntshav mus rau lub ntsws yog dab tsi?
Cov hlab ntsha. Qhov qis dua thiab zoo tshaj vena cava nqa cov ntshav tsis zoo los ntawm lub cev mus rau sab xis atrium. Cov hlab ntsha pulmonary channel tso cov ntshav tsis muaj oxygen los ntawm txoj cai ventricle mus rau hauv lub ntsws, qhov twg oxygen nkag mus rau hauv cov hlab ntsha. Cov hlab ntsws coj cov ntshav muaj cov pa oxygen mus rau sab laug atrium
Cov hlab ntsha twg nqa ntshav mus rau lub ntsws?
Cov hlab ntsws loj, pib los ntawm txoj hlab ntshav sab xis, nqa cov ntshav deoxygenated los ntawm lub plawv mus rau lub ntsws (feem ntau lwm cov hlab ntsha, txawm li cas los xij, nqa cov ntshav oxygenated), kom oxygenated hauv lub ntsws
