Koj puas tau xav txog seb peb daim tawv nqaij ncab thiab rov qab mus rau nws cov duab qub li cas? Nws zoo li ib txoj hlua roj hmab. Peb lub ntsws nthuav dav li cas thaum peb ua pa thiab ua pa tawm? Hnub no peb yuav tham txog tus superhero tom qab tag nrho cov no. Nws lub npe yog Elastin .
Hauv lwm lo lus, elastin yog dab tsi?
Elastin yog ib qho protein tseem ceeb heev hauv peb lub cev. Raws li nws lub npe qhia, nws lub ntsiab yam ntxwv yog elasticity . Xav txog ib txoj hlua roj hmab zoo. Peb tuaj yeem ncab nws ntau npaum li peb xav tau, thiab thaum peb tso mus, nws ntsws rov qab mus rau nws qhov loj qub, puas yog? Ib yam li ntawd, cov protein elastin pab cov nqaij ntawm peb lub cev ncab thiab cog lus dua.
Vim yog lub peev xwm zoo kawg no, elastin muaj ntau nyob rau hauv cov cheeb tsam ntawm peb lub cev uas yuav tsum tau ncab thiab cog lus tas li. Piv txwv li:
- Lub ntsws: Thaum peb ua pa nkag thiab tawm.

Yog li ntawd, elastin puas yog ib hom collagen?
Tsis yog. Qhov no yog ib yam dab tsi uas ua rau ntau tus neeg tsis meej pem. Txawm hais tias elastin thiab collagen yog ob qho tib si protein, lawv ua ob yam sib txawv. Ib yam li thaum ua tsev, koj xav tau cib los ua phab ntsa thiab cov xov hlau los ua cov xov hlau. Koj xav tau ob qho tib si, tab sis lawv ua ob yam sib txawv.
Cov kws kho mob histologist siv cov xim tshwj xeeb los cais qhov txawv ntawm ob qho no. Cov xim no ua rau cov cheeb tsam uas muaj elastin zoo li xim av lossis xim ntshav.
Cia peb saib seb qhov sib txawv tseem ceeb ntawm ob qho no yog dab tsi.
| Yam ntxwv | Elastin | Collagen |
|---|---|---|
| Lub luag haujlwm tseem ceeb | Muab kev ncab/elasticity. Zoo li ib txoj hlua roj hmab. | Muab lub zog, qauv, thiab lub peev xwm dais tau. Zoo li ib tug ncej. |
