Arterioles txuas nrog cov hlab ntsha me me hu ua capillaries. Los ntawm cov phab ntsa nyias ntawm cov hlab ntsha, cov pa oxygen thiab cov as-ham dhau los ntawm cov ntshav mus rau hauv cov ntaub so ntswg, thiab cov khoom pov tseg dhau los ntawm cov ntaub so ntswg mus rau hauv cov ntshav. Los ntawm cov hlab ntsha, cov ntshav nkag mus rau hauv venules, tom qab ntawd mus rau hauv cov hlab ntsha rov qab mus rau lub plawv.
Cov hlab ntsha thiab cov hlab ntsha puas yog tib yam?
Artereries thauj cov ntshav tawm ntawm lub plawv thiab ceg mus rau hauv cov hlab ntsha me, tsim cov hlab ntsha. Arterioles faib cov ntshav mus rau capillary txaj, qhov chaw sib pauv nrog cov ntaub so ntswg lub cev. Capillaries coj rov qab mus rau cov hlab ntsha me me hu ua venules uas ntws mus rau hauv cov hlab ntsha loj dua thiab thaum kawg rov qab mus rau lub plawv.
Qhov txawv ntawm cov hlab ntsha thiab cov hlab ntsha yog dab tsi?
Arterioles nqa ntshav thiab oxygen mus rau hauv cov hlab ntsha me tshaj plaws, cov hlab ntsha. Capillaries tsawg heev lawv tuaj yeem pom nyob rau hauv lub tshuab microscope. Cov phab ntsa ntawm capillaries yog permeable rau oxygen thiab carbon dioxide. Oxygen txav los ntawm lub capillary mus rau lub hlwb ntawm cov ntaub so ntswg thiab lub cev.
Cov hlab ntsha yog dab tsi?
Muaj peb hom hlab ntsha: hlab ntsha, hlab ntsha, thiab capillaries. Txhua yam ntawm no plays lub luag haujlwm tshwj xeeb hauv cov txheej txheem ncig. Cov hlab ntsha nqa oxygenated ntshav tawm ntawm lub plawv. Lawv tawv rau sab nraud tab sis lawv muaj cov txheej sab hauv du ntawm cov hlwb epithelial uas tso cai rau cov ntshav ntws yooj yim.
Dab tsisystem yog arterioles?
Capillary: Arterioles yog ib feem ntawm lub microcirculation system, nrog rau cov hlab ntsha, cov hlab ntsha, cov hlab ntsha, venules, thiab cov hlwb hlwb. Lub microcirculation cuam tshuam cov ntshav ntws hauv cov hlab ntsha me tshaj plaws, suav nrog cov hlab ntsha, capillaries, thiab venules.
