Me ako tātou mō te endothelium - he pūngao huna i roto i tō tinana.

E mōhio ana tātou katoa ka rere te toto puta noa i ō tātou tinana, tika? Kāore tēnei toto e rere noa i roto i tētahi whatunga ngongo e kiia nei ko ngā uaua toto, he rite ki ngā paipa wai. Nō reira, kua whakaaro koe he aha te āhua o roto o ēnei ngongo? I tēnei rā ka kōrero tātou mō tētahi paparanga pūtau whakamiharo, tino angiangi e whakarārangi ana i roto i aua ngongo. Ka kiia tēnei ko te 'endothelium' . Ehara tēnei i te mea he arai noa iho, engari he pūnaha pūtau iti e mahi ana i ngā mahi tino nui e pā ana ki te hauora o tō tinana katoa.

Ki te kī ngāwari, he aha tēnei endothelium?

Whakaarohia kei roto i tō tinana he kiriuhi angiangi, maeneene hoki, kotahi noa te matotoru o te pūtau, pērā i te pakitara pakitara. Ko te endothelium tēnā. He momo pūtau motuhake e kiia nei ko ngā pūtau endothelial.

Kei roto i ēnei wāhi o tō tinana tēnei endothelium:

• Ngā uaua toto: Ngā oko toto nui e kawe ana i te toto mai i te ngākau ki ētahi atu wāhanga o te tinana.
• Ngā uaua: Ko ngā oko toto e kawe ana i te toto mai i te tinana ki te ngākau.
• Ngā uaua toto: He tino angiangi, he ririki ngā oko toto.
• Ngā uaua lymph: Ngā oko toto nō roto i tō tātou pūnaha lymphatic.

Ehara i te mea he pakitara noa iho. He pokapū nui tēnei mō te whakawhitiwhiti kōrero me ngā matūkai i waenga i ō toto me ngā kiko katoa o tō tinana. He mea nui rawa atu tēnei, ā, e whakaaro ana ngā kaipūtaiao ko te endothelium tētahi o ngā okana nui rawa atu o ō tātou tinana. Ae, he okana anō hoki, pērā i te ate me te ngākau.

He aha te mahi a te endothelium ki tō tātou tinana?

He mea whakamiharo te mahi a tēnei paparanga iti o ngā pūtau. Me titiro tātou ki ētahi o ngā mahi matua.

Ka whakahaere i te whakaheke me te whakawhānui o ngā oko toto

Me whānui ake (vasodilate) ō uaua toto ina hiahiatia, me whaiti (vasoconstrict) ina hiahiatia. Ko te endothelium tēnei e whakahaeretia ana.

Whakaarohia pēnei.

• Ina whakakori tinana koe: Me nui ake te toto me te hāora e hiahiatia ana e ō uaua. Ka tukuna e te endothelium ngā tohu hei whakawhanui i ngā oko toto i taua wāhi, kia ngāwari ake ai te rere o te toto.
• I tētahi rā tino makariri: Me pupuri te wera o tō tinana. Mā tēnei ka paku whakawhāiti ngā uaua toto i roto i ō ringaringa me ō waewae, ka āwhina i te rere o te toto ki ō whekau nui.

Ma tenei, ka tino awhina i te whakahaere i to toto toto, me te whakarite kia whiwhi nga whekau katoa i te nui o te toto e tika ana.

Ka whakahaere i te nui o te wai e neke ana mai i te toto ki ngā kiko

He rite te endothelium ki tētahi tātari. Ka tukuna ngā matūkai me te hāora mai i te toto kia haere mā roto i ngā kiko, ā, ka mahi anō hoki hei ārai tiaki e ārai ana i ngā matū kino me ngā paitini kia uru ki roto i te toto. Heoi, ina pāngia koe e te mate, me puta atu ā tātou pūtau ārai mate i roto i te toto ka haere ki te wāhi kei reira te mate. Kātahi ka whakatakoto te endothelium i te ara mō aua pūtau kia tae atu ki reira.

Ka ārai i te toto totoka (Thrombosis)

I te nuinga o te wā, he tino morearea ngā toto totoka i roto i ngā uaua toto, tika? Ka taea e ia te whakaputa i ngā mate kino pēnei i te mate manawa me te whiu. Ka tukuna e te endothelium hauora ngā matū motuhake pēnei i te hauota hauota, e pupuri ana i te rere o te toto me te aukati i te totoka kore e hiahiatia.

He pēhea te rahi o te endothelium? Kei hea ia kei roto i tō tātou tinana?

Ki te pātai mai tetahi kei hea tō ngākau, ka tohu koe ki tō uma. Ki te pātai mai tetahi kei hea tō roro, ka tohu rātou ki tō mahunga. Engari ki te pātai mai tetahi kei hea te endothelium, ka taea e koe te tohu ki tētahi wāhanga o tō tinana. He whānui haere puta noa i te tinana.

Whakaarohia, mehemea ka whakatakotoria ngā uaua toto katoa o te tangata noa mai i te pito ki te pito, ka tata ki te 100,000 kiromita te roa! He nui atu i te nui hei hikoi huri noa i te ao kia rua ngā wā. Ā, kua kapi katoa tēnei roanga i tēnei endothelium. Ki te tangohia tōna horahanga, he nui ake i ētahi kooti tēnehi. Waihoki, he nui atu i te kotahi tiriona (1,000,000,000,000) ngā pūtau endothelial o tēnei pūnaha katoa.

He aha te ngoikore o te Endothelial?

Koinei te wāhanga tino nui me aro atu tātou katoa. Ko te tikanga o te 'Endothelial Dysfunction' ko te pakaru o ngā pūtau endothelial, ā, kāore e taea te mahi tika i tā rātou mahi. He rite ki te mea kua tangohia te uku o te rori, ā, he uaua ki ngā waka te haere.

Ka ahatia ina ngoikore te endothelium tonu?

Ina pakaru te endothelium, ka taratara tōna mata maeneene. Kātahi ka tīmata te kohikohi o te cholesterol kino (LDL) ki aua wāhi taratara. Hei whakautu, ka haere mai ngā pūtau o te pūnaha ārai mate o te tinana ka huihui ki reira. Ka kohikohi katoa ēnei mea, ā, i roto i te wā, ka hangaia he 'paparanga ngako' (pēra) .

I te tipu haere o tēnei paparanga ngako, ka whaiti te uaua toto mai i roto. Kātahi ka aukati i te rere o te toto. Mēnā ka pakaru tēnei paparanga ngako i tētahi rā, ka puta he toto totoka ki taua wāhi, ā, ka ārai katoa i te uaua toto.

Nō reira, ka pāngia pea te tangata he ngoikore te endothelium e ngā āhuatanga mōrearea e whai ake nei:

• Te whakaekenga o te ngakau
• Whiu
• Te mate uaua koronari
• Te mate uaua o te taha
• mate whatukuhu
• Te ātete ki te insulin

Nā, me pēhea tātou e pupuri ai i te hauora o tēnei endothelium?

Ko te rongo pai, ka taea e tātou te tiaki i tēnei endothelium utu nui mā te whakarerekē i ō tātou momo noho.

I roto i ngā kupu māmā noa iho, ka whakaputahia e ō tātou tinana tētahi momo matūriki kino e kiia nei ko ngā 'raruraru kore utu' . Ka kino ēnei i ō tātou pūtau endothelial. Ko ngā mea pai e āwhina ana ki te whakakore i ēnei matūriki kino e kiia ana ko ngā 'antioxidants' . Nō reira, ko tā tātou mahi he whakaiti i te whakaputanga o ngā raruraru kore utu mā te kai i ngā kai e whai kiko ana i ngā antioxidants.

Ngā mea pai hei mahi

Kai atu i ngā kai e whai kiko ana i ngā antioxidants.

• Ngā huawhenua matomato pouri: te pīnihi, te kāreti, te kāreti.
• Ngā hua me ngā huawhenua he kanapa te tae: tōmato, kāreti, pīti, pepa pere, karaka, karepe.
• Ngā witi katoa: raihi parauri, ōti, me te rai.
• Ngā hinu hauora: hinu oriwa, āporo.

Ka taea e koe te kōrero ki tō tākuta mō tēnei momo kai (hei tauira, te kai Mediterranean) me te hanga i ngā huringa e pai ana ki a koe.

Ngā mea kino hei karo

Ka whakanui ake ēnei mea i ngā rauropi kore utu i roto i tō tinana.

• Momi hikareti: Koinei te hoariri tuatahi. Kati i tēnei rā.
• Ngā kai he nui te huka me ngā mea reka: Ka whakanui ake ēnei i te mumura i roto i te tinana.
• Ngā kai tukatuka: Tērā pea kei roto i ēnei ngā ngako me ngā matū kino.
• Te ahotea nui rawa.
• Kāore i te nui te moe.

He mea nui anō hoki te whakakori tinana auau mō te hauora o te endothelial. Ina whakakori tinana koe, ka piki ake te hanga o te hauota hauota, ka noho ora ai ō uaua toto. Ahakoa te hikoi noa mō te 30 meneti i te rā, ka nui te rerekētanga.

Mena kei a koe tētahi mate hauora pēnei i te toto toto tiketike, te mate huka, te cholesterol rānei, he mea nui kia whai i te mahere maimoatanga a tō tākuta . Ko te whāinga o ēnei rongoā he whakahaere i ēnei mate me te whakaiti i te kino ki tō endothelium.
