Ntshav nkag mus rau sab xis atrium thiab dhau los ntawm txoj cai ventricle. Lub ventricle txoj cai tso lub ntshav mus rau lub ntswsqhov twg nws dhau los ua oxygenated. Cov ntshav oxygenated tau coj rov qab mus rau lub plawv los ntawm cov hlab ntsha pulmonary uas nkag mus rau sab laug atrium.
Vim li cas ntshav thiaj li oxygenated hauv lub ntsws?
Thaum lub ventricle puv, lub tricuspid valve kaw. Qhov no txwv tsis pub cov ntshav ntws rov qab mus rau sab xis atrium thaum lub ventricle cog lus. Raws li ventricle cog lus, cov ntshav tawm hauv lub plawv los ntawm lub ntsws pulmonic, mus rau hauv cov hlab ntsha pulmonary thiab mus rau lub ntsws, qhov twg nws yog oxygenated.
ntshav tso pa tawm qhov twg thiab dhau los ua deoxygenated?
Tom qab tawm hauv lub siab, liab ntshav cell taug kev los ntawm cov hlab ntsha mus rau lub ntsws. Nyob ntawd nws khaws oxygen ua deoxygenated liab blood cell tam sim no muaj oxygenated blood cell. Lub blood cell ces ua rau nws rov qab mus rau lub plawv ntawm pulmonary leeg mus rau sab laug atrium.
3 yam kev ncig yog dab tsi?
3 Yam Kev Tshaj Tawm:
- Systemic ncig.
- Pulmonary ncig.
Yuav ua li cas yog tias oxygenated thiab deoxygenated ntshav sib xyaw?
Yog tias muaj kev sib xyaw ua tiav ntawm cov ntshav oxygenated thiab deoxygenated hauv lub plawv ces. a) ntshav raulub ntsws yuav tsis muaj oxygen thiab cov ntaub so ntswg yuav tau txais cov ntshav uas muaj oxygen. … d) Cov ntaub so ntswg yuav tau txais cov ntshav oxygenated tag thiab lub ntsws yuav tau txais cov ntshav deoxygenated.
