Muaj peb hom hlab ntsha Cov hlab ntsha (liab) nqa oxygen thiab cov as-ham tawm ntawm koj lub siab, mus rau koj lub cev cov ntaub so ntswg. Lub veins (xiav) coj cov ntshav tsis muaj oxygen rov qab mus rau lub plawv. Cov hlab ntsha pib nrog lub aorta, cov hlab ntsha loj tawm hauv plawv.
Cov hlab ntsha twg nqa ntshav mus rau lub plawv?
Lub Cev Lub Cev
Lub aorta yog cov hlab ntsha loj uas tawm hauv lub siab. superior vena cava yog cov hlab ntsha loj uas coj cov ntshav ntawm lub taub hau thiab caj npab mus rau lub plawv, thiab qhov qis vena cava coj cov ntshav los ntawm plab thiab ob txhais ceg mus rau hauv lub plawv.
Ob txoj hlab ntsha loj uas nqa ntshav mus rau lub plawv yog dab tsi?
Lub aorta (cov ntshav tseem ceeb rau lub cev) tau tawm mus rau hauv ob txoj hlab ntsha loj (tseem hu ua arteries). Cov hlab ntsha coronary no tawm mus rau hauv cov hlab ntsha me, uas muab cov ntshav oxygen nplua nuj rau tag nrho lub plawv cov leeg. Txoj hlab ntsha sab xis muab cov ntshav rau sab xis ntawm lub plawv.
Cov hlab ntsha twg nqa ntshav mus rau lub plawv sab xis thiab sab laug?
Lub pulmonary artery nqa oxygen-tsis zoo cov ntshav los ntawm txoj cai ventricle mus rau hauv lub ntsws, qhov twg oxygen nkag mus rau hauv cov hlab ntsha. Cov hlab ntsha pulmonary coj cov ntshav uas muaj oxygen mus rau sab laug atrium. Lub aorta nqa cov ntshav uas muaj oxygen rau lub cev los ntawm sab laug ventricle.
5 cov hlab ntsha loj yog dab tsi?
cov ntsiab lus tseem ceeb
- Lub vasculature ua haujlwm nrog lub siab muab lub cev nrog oxygen thiab cov as-ham thiab tshem tawm cov khoom pov tseg.
- Muaj tsib chav ntawm cov hlab ntsha: cov hlab ntsha, cov hlab ntsha, cov hlab ntsha, venules thiab capillaries.

Cov hlab twg nqa ntshav rov qab mus rau lub siab?
cov hlab ntsha: Cov ntshav txav mus los ntawm ntau lub raj hu ua arteries thiab cov leeg, uas ua ke hu ua cov hlab ntsha. Cov hlab ntsha uas nqa ntshav tawm ntawm lub plawv yog hu ua cov hlab ntsha. Cov uas nqa ntshav rov qab mus rau lub plawv yog hu ua veins .
Puas cov hlab ntsha ib txwm nqa cov ntshav oxygenated?
Cov hlab ntsha feem ntau nqa cov ntshav oxygenated thiab cov leeg feem ntau nqa cov ntshav deoxygenated. … Txawm li cas los xij, cov hlab ntsha thiab cov hlab ntsha yog ib qho kev zam rau txoj cai no. Pulmonary veins nqa cov ntshav oxygenated mus rau lub plawv thiab cov hlab ntsha pulmonary nqa cov ntshav deoxygenated tawm ntawm lub plawv.
Cov hlab me me tshaj plaws nyob rau hauv cov hlab ntsha hu ua qhov twg?
Cov hlab ntsha me tshaj plaws, hu ua capillaries, me me heev koj xav tau lub tshuab ntsuas kom pom lawv. Capillaries koom ua cov hlab ntsha loj. Qhov loj dua yog hu ua cov leeg. Cov hlab no nqa ntshav rov qab mus rau lub plawv . Cov hlab ntsha me tshaj plaws lossis cov hlab ntsha hauv cov hlab ntsha yog dab tsi?
