Qhov sib txawv tseem ceeb ntawm cov hlab ntsha thiab cov ntaub so ntswg yog cov ntaub so ntswg yog cov ntaub so ntswg nrog cov ntshav thiab cov hlab ntsha xws li cov hlab ntsha, cov hlab ntsha, thiab cov hlab ntsha thaum cov ntaub so ntswg yog cov ntaub so ntswg uas tsis muaj cov ntshav thiab cov hlab ntsha lymphatic. Yog li, cov ntaub so ntswg tau txais cov ntshav txaus tab sis tsis yog cov ntaub so ntswg.
Cov ntaub so ntswg thiab vascular yog ob hom ntaub so ntswg nyob hauv tib neeg lub cev. Feem ntau cov ntaub so ntswg hauv tib neeg lub cev muaj cov ntshav txaus. Yog li ntawd, lawv yog cov ntaub so ntswg vascular. Txawm li cas los xij, ob peb cov ntaub so ntswg avascular kuj muaj nyob hauv tib neeg lub cev.
Cov ntaub so ntswg vascular yog dab tsi?
Hauv tib neeg cov tshuaj, cov ntaub so ntswg vascular yog cov ntaub so ntswg uas muaj cov hlab ntsha thiab cov hlab ntsha lymphatic. Cov hlab ntsha no nqa ntshav thiab lymph thoob plaws lub cev. Cov hlab ntsha xws li cov hlab ntsha, cov hlab ntsha, thiab cov hlab ntsha thauj gasses xws li oxygen thiab carbon dioxide thiab. Lymphatic hlab ntsha nqa cov kua dej lymphatic ncig lub cev.
Daim duab 01: Cov Ntshav
Cov ntaub so ntswg muaj ntshav txaus. Qee cov ntaub so ntswg xws li cov ntsws thiab lub siab muaj cov hlab ntsha ntau. Yog li ntawd, lawv hu ua cov ntaub so ntswg vascular. Cov ntaub so ntswg yog lwm hom vascularized ntaub so ntswg.
Dab tsi yog Avascular Tissue?
Cov ntaub so ntswg avascular yog cov ntaub so ntswg uas tsis muaj cov hlab ntsha thiab cov hlab ntsha lymphatic. Yog li ntawd, cov ntaub so ntswg no tsis tau txais cov ntshav zoo. Nws ib txwm tau txais cov ntshav tsis txaus.
Daim duab 02: Qhov muag
Cov pob txha mos, lub qhov muag ntawm lub qhov muag thiab txheej epithelial ntawm daim tawv nqaij yog qee cov ntaub so ntswg hauv tib neeg lub cev. Qee cov ntaub so ntswg ib txwm tsis muaj cov hlab ntsha vim lawv txoj haujlwm tuaj yeem raug thaiv los ntawm cov hlab ntsha. Piv txwv li, cov hlab ntsha tsis nyob hauv lub lens vim lawv tuaj yeem pom qhov tsis pom tseeb. Epithelial txheej tau txais cov khoom noj los ntawm kev sib kis ntawm cov khoom los ntawm cov ntaub ntawv hauv qab daus vim tsis muaj cov hlab ntsha. Tab sis txheej txheej epithelial loj hlob ntawm cov ntaub so ntswg vascular. Tendons thiab ligaments kuj tau txais cov ntshav tsis zoo.
Qhov txawv ntawm Vascular thiab Avascular Tissue yog dab tsi?
Cov ntaub so ntswg muaj cov ntshav thiab cov hlab ntsha lymphatic. Nyob rau hauv sib piv, cov ntaub so ntswg avascular tsis muaj cov ntshav thiab lymphatic hlab ntsha. Yog li, vascular cov ntaub so ntswg muaj cov hlab ntsha, leeg, capillaries thiab lymphatic hlab ntsha thaum cov ntaub so ntswg tsis muaj. Ntxiv mus, cov ntaub so ntswg vascular muaj cov ntshav txaus thaum cov ntaub so ntswg tsis tau txais cov ntshav txaus. Cov nqaij mos, cov ntaub so ntswg ntawm daim siab thiab lub ntsws yog qee qhov piv txwv ntawm cov ntaub so ntswg. Cornea thiab lens ntawm lub qhov muag, pob txha mos, epithelium ntawm daim tawv nqaij, thiab lwm yam yog cov piv txwv ntawm cov ntaub so ntswg avascular. Qhov tseeb, feem ntau cov ntaub so ntswg hauv lub cev yog vascular.
Summary – Vascular vs Avascular Tissue
Qhov txawv ntawm cov hlab ntsha thiab cov ntaub so ntswg avascular tshwm sim los ntawm qhov muaj lossis tsis muaj ntshav thiab cov hlab ntsha lymphatic. Qee cov ntaub so ntswg yog vascularized heev vim lawv xav tau cov ntshav txaus rau lawv txoj haujlwm. Qee cov ntaub so ntswg ib txwm tsis muaj cov hlab ntsha vim lawv txoj haujlwm tuaj yeem raug thaiv los ntawm cov hlab ntsha.
