Cov hlab ntsws loj nqa cov ntshav deoxygenated los ntawm txoj hlab ntshav sab xis mus rau lub ntsws . Cov ntshav ntawm no hla dhau cov hlab ntsha nyob sib ze alveoli thiab dhau los ua cov pa oxygen ua ib feem ntawm cov txheej txheem ntawm ua pa.
Kuj tseem paub yog, vim li cas cov hlab ntsha pulmonary nqa cov ntshav deoxygenated?
Cov Cov hlab ntsha pulmonary 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 tias nqa cov ntshav deoxygenated , thiab raug txiav txim siab cov hlab ntsha vim lawv nqa ntshav deb ntawm lub plawv.
Kuj Paub, cov ntshav hauv pulmonary artery txawv li cas? Cov mob ntsws kev ncig yog txawv tshaj li cov txheej txheem hauv cov ntsiab lus uas nyob hauv mob ntsws cov hlab ntsha nqa oxygenated ntshav , qhov twg cov hlab ntsha nqa deoxygenated ntshav.
Dab tsi txuas lub aorta rau pulmonary hlab ntsha?
Qhov thib ob feature ntawm lub plawv fetal uas txawv ntawm lub plawv postnatal yog lub xub ntiag ntawm lub ductus arteriosus (DA nyob rau hauv daim duab). Lub nkoj no txuas cov pulmonary leeg mus rau aorta cov thiab tso cai kom cov ntshav ntws los ntawm pulmonary leeg rau hauv aorta cov , uas nqa nws mus rau lub placenta rau oxygenation.
Qhov twg ntawm lub cev ua rau cov hlab ntsha thiab cov hlab ntsha txuas mus?
Cov pulmonary hlab ntsha nqa cov ntshav oxygen tsawg los ntawm sab xis ntawm lub plawv mus rau lub ntsws. Txheej txheem cov hlab ntsha thauj cov ntshav oxygenated los ntawm sab laug ventricle ntawm lub plawv mus rau lwm qhov lub cev . Cov leeg . Cov pulmonary leeg nqa oxygenated ntshav los ntawm lub ntsws mus rau sab laug atrium ntawm lub plawv.

Cov hlab ntsha qis hauv cov hlab ntsha ntws mus rau qhov twg?
Brachiocephalic leeg
Hom hlab ntshav twg txuas cov hlab ntsha thiab cov hlab ntshav?
Hom hlab ntsha Capillaries yog feeb nyias-walled hlab ntsha uas txuas cov hlab ntsha thiab venules; Nws yog los ntawm cov capillaries uas cov as-ham thiab cov pov tseg tau pauv ntawm cov ntshav thiab cov ntaub so ntswg ntawm lub cev
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 hlab ntsha twg nqa cov ntshav deoxygenated mus rau lub ntsws?
Pulmonary leeg
