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 ntshav deoxygenated , thiab raug txiav txim siab cov hlab ntsha vim lawv nqa ntshav deb ntawm lub plawv.

Tib neeg kuj nug, cov hlab ntsha puas tuaj yeem nqa cov ntshav deoxygenated piav?

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).

Tom qab, lo lus nug yog, cov hlab ntsha twg hauv qab no nqa cov ntshav deoxygenated? Lub siab

Cov hlab ntsha	Muaj nuj nqi
Vena cav	Nqa cov ntshav deoxygenated los ntawm lub cev rov qab mus rau lub plawv.
Pulmonary hlab ntsha	Nqa cov ntshav deoxygenated los ntawm lub plawv mus rau lub ntsws.
Pulmonary leeg	Nqa cov ntshav oxygenated los ntawm lub ntsws mus rau lub plawv.
Aorta	Nqa cov ntshav oxygenated los ntawm lub plawv ncig lub cev.

Tsis tas li ntawd, tag nrho cov hlab ntsha puas nqa cov ntshav oxygenated thiab cov hlab ntsha nqa cov ntshav deoxygenated?

Thawj thiab feem ntau qhov sib txawv tseem ceeb ntawm ob yog qhov ntawd tag nrho cov hlab ntsha nqa ntshav deb ntawm lub siab, thiab tag nrho cov hlab ntsha nqa ntshav mus rau lub plawv los ntawm cov cheeb tsam outlying. Feem ntau cov hlab ntsha nqa cov ntshav oxygenated , thiab feem ntau cov leeg nqa cov ntshav deoxygenated ; lub ntsws cov hlab ntsha thiab leeg yog cov kev zam rau txoj cai no.

Vim li cas cov hlab ntsha pulmonary hu ua cov hlab ntsha txawm tias nws nqa cov ntshav deoxygenated?

Txawm tias nws nqa tsawg oxygenated los yog ntshav deoxygenated , yog ib cov leeg vim nws nqa ntshav deb ntawm lub plawv. Tab sis nyob rau hauv cov ntaub ntawv no, nws tsis nqa nws mus rau tus so ntawm lub cev, nws yog nqa mus rau lub ntsws. Tias yog vim li cas nws yog hu ua cov pulmonary leeg , txawm tias nws nqa tsawg dua cov ntshav oxygenated.

Cov hlab ntsha hlab ntsha thiab cov hlab ntshav muaj dab tsi?

Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg

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 cov hlab ntsha uas muaj oxygenated ntshav lossis cov hlab ntsha?

Cov hlab ntsha tau pom tias yog nqa cov ntshav oxygenated mus rau cov ntaub so ntswg, thaum cov leeg nqa cov ntshav deoxygenated rov qab mus rau lub plawv. Txawm li cas los xij, hauv txoj hlab ntsws, cov hlab ntsha nqa cov ntshav deoxygenated los ntawm lub plawv mus rau lub ntsws, thiab cov hlab ntshav rov qab ntshav los ntawm lub ntsws mus rau lub plawv

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)
