Qhov tseem ceeb ntawm tib neeg cov hlab plawv yog cov plawv , ntshav thiab cov hlab ntsha. Nws suav nrog kev nqus pa, "voj" hla lub ntsws uas cov ntshav oxygenated; thiab cov txheej txheem txheej txheem, "voj" hla tag nrho lub cev los muab cov ntshav oxygenated.
Ib yam li ntawd, nws tau nug, dab tsi yog cov kab mob plawv txhais tau tias hauv lub cev?
Tib neeg cov hlab plawv , cev lawv uas xa cov ntshav los ntawm cov hlab ntsha mus rau thiab los ntawm txhua qhov ntawm lub cev, nqa cov khoom noj thiab cov pa mus rau cov nqaij thiab tshem cov pa roj carbon dioxide thiab lwm yam pov tseg. Nws yog ib lub tubular kaw lawv cov ntshav yog propelled los ntawm cov leeg plawv.
Ib sab saum toj no, dab tsi yog lub cev thiab lub cev ntawm cov hlab plawv? Cov cov hlab plawv yog ua los ntawm plawv thiab cov hlab ntsha. Ua ke, cov kabmob no feem ntau ua haujlwm thauj cov pa oxygen, ntawm cov ntshav, rau koj lub cev, thiab tshem lub cev ntawm cov pa roj carbon dioxide. Cov pa oxygen yog qhov tseem ceeb rau kev ua haujlwm ntawm lub cev lub cev.
Tsis tas li cov lus nug yog, dab tsi yog 5 ntu tseem ceeb ntawm cov hlab plawv?
Ntawm nplooj ntawv no:
- Ntshav.
- Plawv.
- Sab xis ntawm lub plawv.
- Sab laug ntawm lub plawv.
- Cov hlab ntsha.
- Cov hlab ntsha.
- Capillaries.
- Cov leeg.
Lub luag haujlwm ntawm cov hlab plawv yog dab tsi?
Cov kab mob plawv muaj lub plawv, cov hlab ntshav, thiab cov ntshav. Cov kab ke no muaj peb lub luag haujlwm tseem ceeb: Kev thauj mus los cov as -ham , oxygen, thiab cov tshuaj hormones rau cov cell thoob plaws lub cev thiab tshem tawm cov zom zaub mov pov tseg (carbon dioxide, nitrogenous pov tseg).
