Cia peb kawm ntxiv txog cov hlab ntsha me me (capillaries)? Cov hlab ntsha me tshaj plaws hauv koj lub cev!

Koj puas tau xav txog cov hlab ntsha me me hauv peb lub cev? Qhov ntawd yog qhov peb hu ua cov hlab ntsha me me . Lawv zoo li cov xov me me uas khiav thoob plaws peb lub cev. Lawv qhov tseem ceeb tsis tuaj yeem hais ntau dhau. Hnub no, peb yuav tham txog cov hlab ntsha me me no yog dab tsi, lawv ua dab tsi, lawv ua rau muaj kab mob dab tsi, thiab yuav ua li cas kom lawv noj qab nyob zoo.

Cov hlab ntsha yog dab tsi? Cia peb nkag siab yooj yim!

Hais yooj yim xwb, cov hlab ntsha me me yog cov hlab ntsha me me uas khiav thoob plaws koj lub cev. Lawv zoo li cov raj me me uas cov ntshav ntws. Lawv lub luag haujlwm tseem ceeb yog nqa cov as-ham thiab oxygen mus rau cov cell hauv koj cov kabmob thiab cov kab ke hauv lub cev. Lawv kuj nqa cov khoom pov tseg, xws li carbon dioxide , tawm ntawm cov cell ntawd.

Puas muaj cov hom capillaries?

Yog, cov hlab ntsha me me kuj muaj ntau yam duab nyob ntawm seb lawv ua haujlwm li cas. Peb tuaj yeem txheeb xyuas peb hom tseem ceeb:

1. Cov hlab ntsha uas txuas ntxiv mus tas li: Cov no muaj qhov me me (fenestrae) , lossis qhov. Qhov no tso cai rau kev sib pauv cov tshuaj sai. Koj tuaj yeem pom cov hlab ntsha no hauv koj lub raum, txoj hnyuv me, thiab cov qog endocrine .

2. Cov hlab ntsha uas tsis muaj qhov nkag mus tas li: Tsuas yog cov khoom me me xwb thiaj li hla tau cov phab ntsa ntawm cov hlab ntsha no. Cov no pom muaj nyob rau hauv koj lub paj hlwb, nrog rau cov nqaij rog thiab cov leeg nqaij.

3. Cov hlab ntsha sinusoidal: Cov no kuj muaj cov qhov me me (fenestrae). Tsuas yog qee yam khoom thiaj li nkag mus thiab tawm los ntawm lawv. Cov hlab ntsha no feem ntau pom muaj nyob rau hauv koj lub siab thiab tus po .

Ua li cas rau cov hlab ntsha capillaries? Lawv txoj haujlwm yog dab tsi tiag?

Cov hlab ntsha me me (capillaries) yog cov uas ua kom peb lub cev ncig ntshav zoo tag nrho. Qhov ntawd yog, cov hlab ntsha thiab cov leeg ntshav txuas nrog ib leeg los ntawm cov hlab ntsha me me no. Koj paub, cov hlab ntsha nqa cov ntshav uas muaj oxygen ntau los ntawm lub plawv mus rau cov kabmob. Cov leeg ntshav nqa cov ntshav uas tsis muaj oxygen thiab cov khoom pov tseg los ntawm cov kabmob rov qab mus rau lub plawv.

Yog li ntawd, lub luag haujlwm ntawm cov hlab ntsha capillaries yog ua haujlwm ua qhov chaw uas cov khoom los ntawm cov hlab ntsha thiab cov leeg ntshav tau sib pauv . Txawm hais tias cov hlab ntsha thiab cov leeg ntshav nqa cov pa roj thiab cov as-ham thoob plaws lub cev, nws yog cov hlab ntsha no uas xa lawv mus rau lawv qhov chaw xav tau, uas yog cov hlwb. Tseem ceeb heev, puas yog?

Cov hlab ntsha me me ua haujlwm rau ntau yam kabmob thiab cov kab ke hauv peb lub cev. Piv txwv li:

• Cov pob txha pob txha: Pab cov qe ntshav tshiab uas tsim tau nkag mus rau hauv cov hlab ntsha.
• Lub Hlwb: Thaum muab kev noj haus rau lub hlwb, nws pab tsim cov ntshav-lub hlwb thaiv, uas tiv thaiv cov tshuaj lom neeg nkag mus.
• Endocrine system: Pab thauj cov tshuaj hormones mus rau cov kab mob tseem ceeb.
• Raum: Cov hlab ntsha peritubular ntawm no lim cov ntshav, ua zis, thiab rov nqus dej thiab sodium rov qab rau hauv lub cev.
• Siab: Pab tshem tawm cov qe ntshav liab thiab cov kab mob uas tsis zoo.
• Lub ntsws: Lawv pab tso cov pa roj carbon dioxide thiab nqus cov pa oxygen.
• Lymphatic system: Pab sau cov kua dej los ntawm cov nqaij thiab coj lawv mus rau cov qog ntshav.
• Txoj hnyuv me: Thauj cov as-ham uas zom tau thiab muab cov khoom noj rau cov hlwb.

Cov hlab ntsha capillaries nyob qhov twg?

Hauv ntej, cov hlab ntsha capillaries nyob txhua qhov chaw hauv koj lub cev ! Lawv tuaj yeem pom txhua qhov chaw uas cov hlab ntsha thiab cov leeg txuas nrog. Lawv ua haujlwm rau koj cov nqaij thiab cov kabmob ua ib lub network ntawm cov hlab ntsha capillaries ('capillary beds').

Cov no zoo li cas? Lawv me me xwb, puas yog?

Yog lawm, cov hlab ntsha me me yog cov hlab ntsha me tshaj plaws hauv koj lub cev ncig ntshav. Cov kws tshawb fawb yuav tsum siv lub tshuab microscope los saib lawv. Xav txog nws, lawv me dua koj cov plaub hau . Ib qho hlab ntsha feem ntau yog li 5 micrometers (ib micrometer yog ib feem txhiab ntawm ib millimeter!). Lawv me heev uas cov qe ntshav liab yuav tsum hla dhau lawv ib qho dhau ib qho. Ib qho hlab ntsha ntev tsawg dua ib millimeter, uas yog qhov loj li lub taub hau cwj mem.

Cov hlab ntsha me me muaj phab ntsa nyias heev (kwv yees li 1 micrometer tuab), yog vim li cas cov as-ham, kua dej, thiab cov pa roj tuaj yeem nkag thiab tawm tau yooj yim.

Cov feem ntawm cov capillaries yog dab tsi?

Cov capillaries muaj ob lub cell txheej tseem ceeb:

• Cov hlwb endothelial: Cov no nyob hauv cov hlab ntsha capillaries. Lawv tswj cov dej ntws, cov as-ham, thiab cov pa roj.
• Cov hlwb Epithelial: Cov no tsim ib txheej tiv thaiv nyob ib puag ncig cov hlwb endocrine.

Cov mob thiab cov kab mob uas feem ntau cuam tshuam rau cov hlab ntsha capillaries yog dab tsi?

Cov hlab ntsha tawg yog ib qho uas pom ntau heev. Lawv tuaj yeem tshwm sim thaum koj hnoos lossis ntuav tawv. Thaum cov hlab ntsha tawg no, lawv los ntshav, ua rau muaj cov xim me me zoo li lub qhov ntswg (petechiae) ntawm daim tawv nqaij. Feem ntau, cov no yuav kho tau lawv tus kheej.

Sib nrug ntawm qhov ntawd, ntawm no yog qee qhov lwm yam mob uas tuaj yeem cuam tshuam rau cov capillaries:
