Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Mhuka dzose dzakaumbwa nemasero, akakomberedzwa nemasero akasiyana-siyana anoumbwa ne collagen uye glycoproteins. Mukati mokukura, mhuka inonzi extracellular matrix inoumba gadziriro inochinjika zvikuru iyo masero anogona kufamba pamusoro payo uye kurongwazve, zvichiita kuti kuumbwa kwezvivako zvakaoma kuve kunobvira. Izvi zvingava zvakapfava, zvichiita kuti pave nezvimiro zvakaita semakwati, mapfupa, uye mapfundo. Kusiyana neizvi, masero ezvimwe zvisikwa zvine masero akawanda (kunyanya algae, zvinomera, uye fungi) anochengetwa panzvimbo nemadziro emasero, uye nokudaro anokura nokukura kunopfuurira. Masero emhuka chete ndiwo ane mapfundo anonzi tight junctions, gap junctions, uye desmosomes. Izvi zvinosanganisira tsandanyama, dzinoita kuti munhu akwanise kufamba, uye tsinga, dzinoendesa mashoko uye dzinoshanda pamwe chete nomuviri. Kazhinji, kunewo kamuri yomukati yokugaya ine buri rimwe (muCtenophora, Cnidaria, uye flatworms) kana kuti maburi maviri (mubilaterians dzakawanda).  Mubvunzo: matrix emamwe masero anoumbwa mumhuka uye anogona kuumbwa nechii?
