Qhov Tseem Ceeb Qhov txawv - Cov hlab ntsha vs Arterioles
Lub circulatory system los yog cov hlab plawv system yog ib tug network ntawm cov kabmob thiab cov hlab ntsha uas thauj cov ntshav, as-ham, cov tshuaj hormones, oxygen thiab lwm yam gases thoob plaws hauv lub cev. Lub plawv yog lub hauv paus tseem ceeb ntawm cov hlab plawv system. Cov hlab ntsha, uas yog cov qauv tubular hollow, thauj cov ntshav los ntawm lub cev. Muaj peb hom hlab ntsha loj hu ua cov hlab ntsha, cov hlab ntsha thiab cov hlab ntsha. Cov hlab ntsha nqa ntshav tawm ntawm lub plawv. Capillaries pab txhawb kev sib pauv dej thiab tshuaj ntawm cov ntshav thiab cov ntaub so ntswg. Cov leeg ntshav rov qab los ntawm capillaries mus rau lub plawv. Cov hlab ntsha tau muab faib ua cov hlab ntsha me me lossis cov hlab ntsha hu ua arterioles ua ntej tuaj yeem ua rau cov hlab ntsha. Cov ntshav los ntawm lub plawv mus ntawm cov hlab ntsha, cov hlab ntsha, thiab cov hlab ntsha mus rau lub cev nqaij daim tawv thiab rov qab mus rau lub plawv ntawm venules thiab cov leeg. Qhov sib txawv tseem ceeb ntawm cov hlab ntsha thiab cov hlab ntsha yog cov hlab ntsha yog cov hlab ntsha uas nqa ntshav los ntawm lub plawv thaum cov hlab ntsha me me uas tau txais cov ntshav los ntawm cov hlab ntsha loj dua thiab dhau mus rau capillaries.
Cov hlab ntsha yog dab tsi?
Cov hlab ntsha yog ib hom hlab ntsha uas nqa ntshav tawm ntawm lub plawv. Txawm li cas los xij, cov hlab ntsha coronary muab cov ntshav oxygen nplua nuj rau cov leeg plawv. Cov hlab ntsha, tshwj tsis yog cov hlab ntsha pulmonary uas mus rau hauv lub ntsws, muaj cov ntshav oxygenated. Lub plawv tso ntshav nrog lub siab. Yog li ntawd, cov hlab ntsha muaj cov ntshav siab. Txij li thaum cov ntshav nyob rau hauv lub siab siab, cov hlab ntsha yog tsim los ntawm cov nqaij ntshiv cov phab ntsa kom zam lub siab. Cov hlab ntsha muaj zog thiab elastic. Yog li, lawv tuaj yeem tswj hwm tus nqi thiab tus nqi ntawm cov ntshav mus rau hauv lub cev.
Cov hlab ntsha loj tshaj plaws hauv lub cev, uas yog lub raj tseem ceeb uas tuaj ncaj qha los ntawm lub plawv, hu ua aorta. Aorta ceg mus rau hauv lub network ntawm cov hlab ntsha thiab khiav thoob plaws hauv lub cev. Cov hlab ntsha ces ceg mus rau hauv cov hlab ntsha me me hu ua arterioles.
Daim duab 01: Cov hlab ntsha thiab lwm cov hlab ntsha
Cov leeg nqaij leeg yog tsim los ntawm peb txheej ntawm cov ntaub so ntswg du. Lawv yog intima, media, thiab adventitiia. Intima yog txheej txheej txheej txheej los ntawm endothelium. Adventitia yog cov ntaub so ntswg uas txuas cov hlab ntsha mus rau cov ntaub so ntswg nyob ze.
Dab tsi yog Arterioles?
Arterioles yog ib hom ntawm cov hlab ntsha me uas tawm ntawm cov hlab ntsha. Lawv yog ib feem ntawm microcirculation. Lawv pib los ntawm cov hlab ntsha thiab txuas ntxiv mus rau hauv capillaries. Yog li ntawd, arterioles faib cov ntshav mus rau capillaries. Txoj kab uas hla ntawm cov hlab ntsha yog tsawg dua piv rau cov hlab ntsha. Txoj kab uas hla no yog kho kom tswj cov ntshav ntws. Lub thickness ntawm phab ntsa kuj tsawg dua piv rau cov hlab ntsha.
Daim duab 02: Arterioles
Arterioles feem ntau yog tsim los ntawm ib lossis ob txheej ntawm cov leeg nqaij. Arterioles muaj cov ntshav tsis muaj zog thiab tshaj tawm. Qhov no ua rau muaj kev sib pauv roj thiab cov khoom noj hauv cov hlab ntsha.
Dab tsi zoo sib xws ntawm cov hlab ntsha thiab cov hlab ntsha?
- Cov hlab ntsha thiab cov hlab ntsha thauj cov ntshav oxygenated.
- Cov hlab ntsha thiab cov hlab ntsha muaj zog thiab yoog raws phab ntsa
Dab tsi yog qhov txawv ntawm cov hlab ntsha thiab cov hlab ntsha?

Summary – Arteries vs Arterioles
Cov hlab ntsha thiab cov hlab ntsha yog ib feem ntawm cov ntshav ncig. Cov hlab ntsha yog cov hlab ntsha uas nqa cov ntshav tawm ntawm lub plawv. Cov hlab ntsha txuas ntxiv mus rau hauv cov hlab ntsha me me hu ua arterioles. Arterioles ntxiv faib mus rau hauv cov hlab ntsha uas yog cov hlab ntsha me me uas pab txhawb kev sib pauv dej thiab cov as-ham ntawm cov ntshav thiab hauv nruab nrog cev. Qhov no yog qhov txawv ntawm cov hlab ntsha thiab cov hlab ntsha.
