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.
Pom zoo:
Puas yog cov hlab ntsha tawg puas yuav kho tau?
(Txawm tias nws zoo li nws.) Cov hlab ntsha tawg feem ntau pom muaj nyob ntawm lub ntsej muag lossis ob txhais ceg thiab tuaj yeem ua txhaum ntawm ntau yam. Cov ntsiab lus xws li raug tshav ntuj, rosacea, haus cawv, huab cua hloov pauv, cev xeeb tub, noob caj noob ces, thiab lwm yam ua rau lawv tshwm sim.
Puas yog cov hlab ntshav thiab cov hlab plawv zoo ib yam?
Cov kab mob plawv yog qee zaum hu ua ntshav-vascular, lossis tsuas yog cov hlab ntshav, system. Nws muaj lub plawv, uas yog cov khoom siv lub cev, thiab lub kaw lus kaw ntawm cov hlab ntsha hu ua cov hlab ntsha, cov hlab ntsha, thiab cov hlab ntsha.
Puas yog cov hlab ntsha loj dua cov hlab ntsha?
Arterioles nqa ntshav thiab oxygen mus rau hauv cov hlab ntsha me tshaj plaws, cov hlab ntsha. Capillaries yog li ntawd small lawv tsuas pom tau nyob hauv lub tshuab tsom. Cov phab ntsa ntawm capillaries yog permeable rau oxygen thiab carbon dioxide.
Puas yog cov hlab ntsha tawv tawv yog mob plawv?
Cov quav hniav tuaj yeem ua rau koj cov hlab ntsha nqaim, thaiv cov ntshav ntws. Cov quav hniav kuj tuaj yeem tawg, ua rau cov ntshav txhaws. Txawm hais tias atherosclerosis feem ntau suav tias yog teeb meem plawv, nws tuaj yeem cuam tshuam cov hlab ntsha nyob txhua qhov chaw hauv koj lub cev.
Puas yog qhov nyuaj ntawm cov hlab ntsha thiab cov membranous?
Dab tsi yog lub luag haujlwm ntawm lub cytoskeleton? Cov txheej txheem nyuaj ntawm flattened vesicles thiab membranous raws uas muaj ribosomes txuas rau nws nto. Yuav ua li cas muaj lub hnab ntim membranous? Golgi Apparatus: Ib qho organelle hauv eukaryotic hlwb uas muaj pawg ntawm cov hnab membranous tiaj tus uas hloov kho, khaws cia, thiab cov khoom siv ntawm endoplasmic reticulum.
