Ua noʻonoʻo paha ʻoe e pili ana i nā kīʻaha koko liʻiliʻi i loko o ko kākou kino? ʻO ia ka mea a kākou e kapa nei he mau capillaries . Ua like lākou me nā kaula lahilahi e holo ana ma loko o ko kākou kino. ʻAʻole hiki ke hoʻonui ʻia ko lākou koʻikoʻi. I kēia lā, e kamaʻilio kākou e pili ana i ke ʻano o kēia mau capillaries, kā lākou hana, nā maʻi a lākou e hoʻoulu ai, a pehea e mālama ai iā lākou i ke olakino.
He aha nā capillaries? E hoʻomaopopo maʻalahi kākou!
I ka ʻōlelo maʻalahi, ʻo nā capillaries nā kīʻaha koko liʻiliʻi e holo ana ma loko o kou kino. Ua like lākou me nā ʻōmole liʻiliʻi e kahe ai ke koko. ʻO kā lākou hana nui ka lawe ʻana i nā meaʻai a me ka oxygen i nā ʻāpana i loko o kou mau ʻōkana a me nā ʻōnaehana kino. Lawe pū lākou i nā huahana ʻōpala, e like me ke kalapona ʻokikene , mai loko mai o kēlā mau ʻāpana.
E noʻonoʻo i kēia ʻano. Ua like ia me kekahi e lawe mai ana i kahi puʻu mea i kou hale a lawe pū me lākou i nā ʻōpala a pau. Ke hana nei kēia ma kou kino holoʻokoʻa, ma nā wahi like ʻole. ʻAʻole anei he mea kupaianaha?
Aia kekahi mau ʻano o nā capillaries?
ʻAe, he nui nā ʻano o nā capillaries ma muli o kā lākou hana. Hiki iā mākou ke ʻike i ʻekolu mau ʻano nui:
1. Nā capillaries fenestrated hoʻomau: He mau puka liʻiliʻi kēia (fenestrae) , a i ʻole nā lua. ʻAe kēia i ka hoʻololi wikiwiki ʻana o nā mea. Hiki iā ʻoe ke ʻike i kēia ʻano capillaries i loko o kou mau puʻupaʻa, ka ʻōpū liʻiliʻi, a me nā kelepa endocrine .
2. Nā capillaries hoʻomau ʻole i hoʻokomo ʻia i loko o ka fenestrated: ʻO nā ʻāpana liʻiliʻi loa wale nō ke hiki ke hele ma waena o nā paia o kēia ʻano capillaries. Loaʻa kēia mau mea i loko o kāu ʻōnaehana nerve, a me nā ʻiʻo momona a me nā ʻiʻo.
3. Nā capillaries sinusoidal: Loaʻa i kēia mau lua liʻiliʻi (fenestrae). ʻO kekahi mau mea wale nō ke komo a puka ma o lākou. ʻO kēia ʻano capillaries ka mea maʻamau i loko o kou ake a me ka spleen .
He aha ka mea e hana ʻia i nā capillaries? He aha kā lākou hana?
ʻO nā capillaries ka mea e hoʻopau ai i kā mākou ʻōnaehana kaʻapuni. ʻO ia hoʻi, ua pili nā aʻa a me nā veins kekahi i kekahi ma o kēia mau capillaries. ʻIke ʻoe, lawe nā aʻa i ke koko momona i ka oxygen mai ka puʻuwai a i nā ʻōpū. Lawe nā veins i ke koko deoxygenated a me nā huahana ʻōpala mai nā ʻōpū i ka puʻuwai.
No laila, ʻo ka hana a nā capillaries ke hana ma ke ʻano he wahi e hoʻololi ʻia ai nā mea e puka mai ana mai nā aʻa a me nā veins . ʻOiai ke lawe nei nā aʻa a me nā veins i nā kinoea a me nā meaʻai ma ke kino holoʻokoʻa, ʻo kēia mau capillaries ka mea e lawe iā lākou i ko lākou mau wahi i manaʻo ʻia, ʻo ia hoʻi nā cell. He mea nui loa, ʻeā?
Hoʻohana nā capillaries i nā ʻano ʻāpana like ʻole a me nā ʻōnaehana i loko o ko mākou kino. Eia kekahi laʻana:
- Iwi iwi: Kōkua i nā hunaola koko hou i hoʻokumu ʻia e komo i ke koko.
- Lolo: ʻOiai e hāʻawi ana i ka meaʻai i ka lolo, kōkua ia i ke kūkulu ʻana i ka pale koko-lolo, kahi e pale ai i nā mea ʻino mai ke komo ʻana.
- ʻŌnaehana Endocrine: Kōkua i ka lawe ʻana i nā hormones i nā ʻōkana pili.
- Nā puʻupaʻa: ʻO nā capillaries peritubular maanei e kānana i ke koko, hana i ka mimi, a hoʻihoʻi hou i ka wai a me ka sodium i loko o ke kino.
- ʻAkepaʻa: Kōkua i ka wehe ʻana i nā hunaola koko ʻulaʻula a me nā bacteria kīnā.
- Nā māmā: Kōkua lākou i ka hoʻokuke ʻana i ke kalapona ʻokikene a lawe i ka oxygen.
- ʻŌnaehana Lymphatic: Kōkua i ka hōʻiliʻili ʻana i nā wai mai nā ʻiʻo a kuhikuhi iā lākou i nā lymph nodes.
- ʻŌpū liʻiliʻi: Lawe i nā meaola i hoʻoheheʻe ʻia a hāʻawi i ka meaʻai i nā pūnaewele.
Aia i hea nā capillaries?
I ka pōkole, aia nā capillaries ma nā wahi āpau o kou kino ! Hiki ke loaʻa iā lākou ma nā wahi a pau e pili ai nā aʻa a me nā veins. Hana lākou i kāu mau ʻiʻo a me nā ʻōpū ma ke ʻano he pūnaewele o nā capillaries ('capillary beds').
Pehea ke ʻano o kēia mau mea? He liʻiliʻi lākou, ʻeā?
ʻAe, ʻo nā capillaries nā kīʻaha koko liʻiliʻi loa i loko o kāu ʻōnaehana hoʻohele koko. Pono nā kānaka noiʻi e hoʻohana i kahi microscope e ʻike iā lākou. E noʻonoʻo e pili ana i ia mea, ʻoi aku ka liʻiliʻi o lākou ma mua o kou lauoho . ʻO ke capillary maʻamau ma kahi o 5 micrometers (ʻo ka micrometer hoʻokahi tausani o ka millimeter!). He liʻiliʻi loa lākou a pono nā hunaola koko ʻulaʻula e hele ma waena o lākou i hoʻokahi. ʻOi aku ka liʻiliʻi o ke capillary ma mua o hoʻokahi millimeter ka lōʻihi, ʻo ia hoʻi ka nui o ka wēlau peni.
He lahilahi loa nā paia o nā capillaries (ma kahi o 1 micrometer ka mānoanoa), ʻo ia ke kumu e hiki ai i nā meaʻai, nā wai, a me nā kinoea ke komo a puka maʻalahi.
He aha nā ʻāpana o nā capillaries?
ʻElua papa nui o nā cell i loko o nā capillaries:
- Nā pūnaewele endothelial: Aia kēia mau mea i loko o nā capillaries. Hoʻomalu lākou i ke kahe o nā wai, nā meaʻai, a me nā kinoea.
- Nā pūnaewele Epithelial: Hoʻokumu kēia i kahi papa pale a puni nā pūnaewele endocrine.
He aha nā kūlana a me nā maʻi maʻamau e hoʻopilikia ai i nā capillaries?
He mea maʻamau loa nā capillaries haki. Hiki ke loaʻa iā ʻoe ke ʻū a luaʻi paha me ka ikaika. Ke pohā kēia mau capillaries, kahe ke koko, e hana ana i nā ʻano liʻiliʻi, e like me ke kiko kiko (petechiae) ma ka ʻili. ʻO ka hapa nui o ka manawa, hoʻōla kēia mau mea iā lākou iho.
Ma waho aʻe o kēlā, eia kekahi mau kūlana ʻē aʻe e hiki ke hoʻopilikia i nā capillaries:
- ʻO ka maʻi arteriovenous (AVM):He kūlana kahi e hihia ai nā aʻa a me nā veins o ka lolo a i ʻole ke kaula spinal a kāpae i nā capillaries. Hiki i kēia mau mea ke hana i loko o nā lālā, ke kino, a me nā ʻōpū ʻē aʻe.
- ʻO ka angiosarcoma capillary: He ʻano maʻi kanesa kakaikahi e kū mai ana mai nā pūnaewele endothelial a hiki ke hoʻopilikia i nā capillaries.
- ʻO ka maʻi leaka capillary: He kūlana e hāʻule koke ai ke koko. I kekahi manawa pono kēia i ka mālama ulia pōpilikia.
- ʻO ka telangiectasia hemorrhagic hoʻoilina: He maʻi kīʻaha koko i hoʻoilina ʻia kahi e ulu ai nā ulu ʻano ʻē (telangiectases) a hiki ke haki. Ua kapa ʻia hoʻi ʻo Osler-Weber-Rendu syndrome.
- Macular degeneration: Ka hōʻino ʻana i loko o ka maka ma muli o nā leaka capillary.
- ʻO ka maʻi maʻi Microcephaly-capillary malformation: Dilated capillaries i loko o ka poʻe me nā poʻo liʻiliʻi ma mua o ka maʻamau.
- ʻAila waina awa: He hōʻailona hānau i hana ʻia e nā capillaries i hana pono ʻole ʻia.
- ʻO ka angioma spider: Nā kīʻaha koko liʻiliʻi e lālā ana mai kahi kikowaena, maʻamau ma ka maka, ka ʻāʻī, a i ʻole ka umauma. Ua kapa ʻia hoʻi he spider nevus a i ʻole spider telangiectasia.
- ʻŌhelopapa hānau: He puʻu o nā kīʻaha koko ʻulaʻula ʻeleʻele ma luna o ka ʻili.
- Vasculitis: Ka mumū o nā kīʻaha koko. Hiki i kēia ke hoʻopilikia i nā capillaries. Hiki i kēia ke alakaʻi i nā pilikia e like me ka haki ʻana a me ka paʻa ʻana o nā kīʻaha koko.
He aha nā hōʻailona maʻamau o nā maʻi capillary?
Hiki i nā kūlana e hoʻopilikia i nā capillaries ke hana i nā hōʻailona e like me:

He aha nā hoʻokolohua e hana ʻia e nānā i ke olakino o nā capillaries?
Hiki ke hana i nā hoʻokolohua e like me kēia e ʻike ai inā he mau kūlana e hoʻopilikia ai i nā capillaries:
- Nā hoʻāʻo koko
- Nānā MRI
- Nānā CT
- ʻAngiogram
- Nānā PET
- Hoʻokolohua maka
- Hoʻāʻo maka 'OCT'
He aha nā lāʻau lapaʻau maʻamau no nā maʻi capillary?
Hiki ke mālama ʻia nā kūlana e pili ana i nā capillaries ma nā ʻano penei:
- Nā lāʻau lapaʻau
- ʻOki ʻana a i ʻole nā ʻoki liʻiliʻi
- Hoʻōla radiation
- Kemoterapia
- Hoʻoili koko
Pehea e mālama ai i ke olakino o nā capillaries?
Pono ʻoe e mālama i kou mau capillaries e like me kou mālama ʻana i kou mau kīʻaha koko ʻē aʻe. ʻO ia hoʻi:
- E hoʻoikaika kino no ka liʻiliʻi he 30 mau minuke i ka lā, ʻelima mau lā o ka pule (150 mau minuke ka huina).
- Ka hoʻemi ʻana i ka waiʻona a me nā mea inu caffeine.
- Ka mālama ʻana i kahi kaumaha olakino e kūpono iā ʻoe.
- E pale i ka puhipaka a me ka hoʻohana ʻana i nā huahana paka ʻē aʻe.
- E ʻike pinepine i kahi ophthalmologist no nā hoʻokolokolo maka.
Eia kekahi, e hana pū me kāu kauka e hoʻokele i nā kūlana e like me kēia e hiki ke hoʻopilikia i ke olakino o kou mau kīʻaha koko:
- Maʻi diabetes
- Kolesterol kiʻekiʻe
- Ke koko kiʻekiʻe
- Ke kaumaha
Āhea ʻoe e ʻike ai i ke kauka?
I kekahi manawa hiki i kāu kauka ke ʻike i kahi maʻi capillary ma mua o kou loaʻa ʻana o nā hōʻailona. Hiki i kēia ke kōkua iā ʻoe e hoʻomaka i ka lāʻau lapaʻau ma mua o ka lilo ʻana i mea ʻino. He ʻoiaʻiʻo loa kēia inā ʻoe e hoʻomau i nā mea e like me nā nānā makahiki.
E ʻike i ke kauka inā loaʻa iā ʻoe nā hōʻailona o ka maʻi koko:
- Nā pahū ʻana o ke kapikala
- Inā ʻike ʻia ua hoʻonui ʻia nā kīʻaha koko ma nā wāwae
- Inā he ʻeha kekahi ʻaoʻao o ke kino a manaʻo paha ʻaʻole hiki iā ʻoe ke manaʻo i kekahi mea
- Inā ʻeha kou mau wāwae ma hope o kahi hoʻoikaika kino iki
- Inā he mau loli koke i ka ʻike
He aha ka ʻokoʻa ma waena o kahi vein a me kahi capillary?
He mea maʻalahi loa ia. ʻO ka hana a ka aa koko, ma hope o ka lawe ʻana o kāu mau cell i kā lākou mea e pono ai mai ke koko, lawe lākou i ke koena o ke koko i ka puʻuwai. Lawe nā aa koko i ke koko i loaʻa nā huahana ʻōpala e like me ke kalapona ʻokikene. Akā, ua like ke capillary me kahi kikowaena hoʻololi . Loaʻa i kāu mau cell ka mea e pono ai lākou ma ia ʻano, a loaʻa i kāu mau cell ka mea e pono ai lākou ma ia ʻano.
Ke noʻonoʻo mākou i nā kahawai nui e lawe ana i ke koko ma o ko mākou kino, poina pinepine mākou i kēia mau capillaries liʻiliʻi. Akā ʻo lākou nā mea e lawe ana i nā mea i nā wahi kūpono . E like me nā ʻāpana ʻē aʻe o ko mākou kino, hiki iā lākou ke loaʻa nā pilikia. No laila, ʻo ka mālama ʻana i kāu ʻōnaehana kahe koko olakino ma o ka hoʻoikaika kino mau a me ka ʻai ʻana i ka meaʻai momona e kōkua pū i kou mau capillaries.
