Arteries thiab arterioles muaj piv tuab nqaij phab ntsa vim ntshav siab hauv lawv yog siab thiab vim tias lawv yuav tsum kho lawv txoj kab uas hla kom tswj ntshav siab thiab tswj ntshav ntws. Cov hlab ntsha tuaj yeem nthuav dav kom haum rau cov ntshav ntxiv.
Ntxiv mus, puas capillaries muaj cov phab ntsa tuab?
Capillaries txuas cov ceg me tshaj plaws ntawm cov hlab ntsha thiab cov hlab ntsha. Cov phab ntsa ntawm capillaries yog ib leeg xwb tuab . Capillaries Yog li cia cov molecules diffuse thoob plaws lub phab ntsa capillary . Qhov kev sib pauv ntawm cov molecules no tsis tuaj yeem hla lub phab ntsa ntawm lwm hom hlab ntsha vim cov phab ntsa yog ib yam nkaus tuab.
Tsis tas li ntawd, hom ntshav dab tsi ua rau arterioles nqa? Arterioles nqa ntshav thiab oxygen mus rau qhov tsawg tshaj plaws ntshav cov hlab ntsha, capillaries.
Ib tus kuj yuav nug, vim li cas cov hlab ntsha tseem ceeb?
Arterioles . Ib cov hlab ntsha yog cov hlab ntsha me me uas ua rau cov hlab ntsha. Cov qhov tseem ceeb ntawm cov hlab ntsha yog tias lawv yuav yog thawj qhov chaw ntawm kev tiv thaiv thiab kev tswj ntshav siab.
Puas yog cov hlab ntsha me me?
Cov hlab ntsha thiab cov hlab ntsha Cov cov hlab ntsha branch ua me dua thiab me dua cov hlab ntsha, thaum kawg ua heev me me nkoj npe cov hlab ntsha . Cov hlab ntsha thiab cov hlab ntsha muaj cov leeg nqaij uas tuaj yeem kho lawv txoj kab uas hla kom nce lossis txo cov ntshav ntws mus rau ib feem ntawm lub cev.

Dab tsi ua rau tuab ntawm phab ntsa hauv plawv?
Hypertrophic cardiomyopathy tshwm sim yog tias lub plawv cov leeg nqaij nthuav dav thiab ua rau cov phab ntsa ntawm lub ventricles (feem ntau yog sab laug ventricle) kom tuab. Qhov me me ntawm lub ventricle feem ntau tseem nyob li qub, tab sis qhov tuab tuaj yeem thaiv cov ntshav ntws tawm ntawm lub ventricle
Cov phab ntsa ntawm cov hlab ntshav tuab npaum li cas?
Lub capillary yog cov hlab ntshav me me los ntawm 5 txog 10 micrometres (Μm) hauv txoj kab nruab nrab, thiab muaj phab ntsa ib lub cell endothelial tuab. Lawv yog cov hlab ntshav me tshaj plaws hauv lub cev: lawv xa cov ntshav nruab nrab ntawm cov hlab ntsha thiab cov hlab ntshav
Qhov tseem ceeb ntawm qhov sib txawv ntawm tuab ntawm phab ntsa ntawm aorta yog dab tsi?
Dab tsi yog qhov tseem ceeb ntawm qhov sib txawv ntawm tuab ntawm phab ntsa ntawm aorta thiab phab ntsa ntawm lub ntsws ntsws? Cov phab ntsa tuab ntawm aorta tso cai kom tiv taus siab dua ntawm cov ntshav tso tawm los ntawm lub ventricle
Nws txhais li cas yog tias koj phab ntsa hauv lub zais zis tuab dua?
Gallstones feem ntau pom zoo ntawm ultrasound. Tsis tas li, cov phab ntsa hauv lub zais zis uas pom ntawm ultrasound tuaj yeem txhais tau tias koj yuav muaj mob hnyav los yog mob cholecystitis. Cov ducts loj loj qhia tau hais tias ib lub pob zeb tuaj yeem dhau los ntawm lub gallbladder thiab mus rau hauv cov kav dej ntau, ua rau txhaws
Cov phab ntsa ntawm lub gallbladder tuab npaum li cas?
Feem ntau, cov phab ntsa ntawm lub zais zis tsawg dua 7 hli tuab, nthuav tawm qhov tsis sib xws thiab qhov pom trilaminar (3,9,11)
