Hauv qhov no, dab tsi yog tib neeg cov ntshav ncig?

Cov circulatory system muaj peb tus neeg ywj pheej tshuab uas ua haujlwm ua ke: lub plawv (hlab plawv), lub ntsws (ntsws), thiab cov hlab ntsha, cov hlab ntshav, lub plawv thiab cov hlab ntsha portal (kab ke). Cov lawv yog lub luag haujlwm rau cov ntshav, cov khoom noj khoom haus, cov pa oxygen thiab lwm yam roj cua, thiab ntxiv rau cov tshuaj hormones rau thiab los ntawm cov cell.

Tom qab ntawd, lo lus nug yog, cov ntshav ntws hla lub cev yog li cas? Ntshav nkag mus rau hauv lub siab dhau ob lub hlab ntsha loj, qhov qis dua thiab zoo dua vena cava, ua rau cov pa oxygen tsis zoo ntshav los ntawm lub cev mus rau sab xis atrium ntawm plawv. Raws li daim ntawv cog lus ventricle, ntshav nplooj plawv dhau pulmonary valve, mus rau hauv cov hlab ntsha pulmonary thiab lub ntsws uas nws tau oxygenated.

Tsis tas li ntawd, dab tsi yog cov kev hloov pauv hauv lub cev?

Tshaj tawm Paub meej. Cov ntshav circulatory system ( cov hlab plawv ) xa cov as-ham thiab oxygen rau tag nrho cov hlwb hauv lub cev. Nws suav nrog lub plawv thiab cov hlab ntshav khiav thoob plaws lub cev. Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; cov leeg nqa nws rov qab mus rau lub siab.

Dab tsi yog hom circulatory system?

Muaj ob lub ntsiab hom kev ncig ua haujlwm : qhib circulatory systems thiab kaw circulatory systems . Qhib circulatory systems yog tshuab qhov twg sab hauv nruab nrog cev thiab cov nqaij hauv lub cev nyob ib puag ncig ntshav ncig kua.
