ʻO nā kīʻaha koko liʻiliʻi loa i loko o ko mākou kino: E pili ana i nā capillaries mau!

Ua noʻonoʻo paha ʻoe i nā kīʻaha koko liʻiliʻi i loko o ko kākou kino? E like me kahi pūnaewele o nā alanui liʻiliʻi i hohola ʻia ma kahi ʻāina, ʻo ia nā mea e lawe ana i nā meaʻai a me ka oxygen i ko kākou mau cell. ʻO nā capillaries kekahi o kēlā mau kīʻaha koko koʻikoʻi loa, liʻiliʻi. Ma waena o kēia mau capillaries, i kēia lā e kamaʻilio mākou e pili ana i ke ʻano maʻamau a kūikawā o nā capillaries, ʻo ia hoʻi nā "Continuous Capillaries". E kamaʻilio kākou e pili ana i kēia me ka maʻalahi, ma ke ʻano hiki iā ʻoe ke hoʻomaopopo.

He aha kēia mau 'Capillaries Hoʻomau'?

I ka ʻōlelo maʻalahi, ʻo nā capillaries hoʻomau ke ʻano maʻamau o ke capillary i loko o ko mākou kino. E like me nā kīʻaha koko ʻē aʻe, ua uhi ʻia lākou me kahi ʻano cell kūikawā i kapa ʻia ʻo nā cell endothelial. Ua kapa ʻia lākou he "hoʻomau" no ka mea ua kokoke loa nā cell kekahi i kekahi, kokoke i ka lālani, me ka ʻole o nā hakahaka. ʻO ke ʻano kēia, ʻaʻohe hakahaka nui i loko o ka paia, a ua pili mau nā cell kekahi i kekahi.

E noʻonoʻo i kēia ʻano, ʻo ia nā kīʻaha koko liʻiliʻi loa o ko kākou kino. ʻO kēia nā mea e lawe i ke koko, nā meaʻai, a me ka oxygen i ko kākou mau cell. ʻO kēia nā ʻāpana liʻiliʻi loa o ko kākou ʻōnaehana vascular.

Aia kekahi mau ʻano capillaries hoʻomau?

ʻAe, ʻelua ʻano nui o kēia mau capillaries hoʻomau. E nānā kākou i ke ʻano o lākou.

1. Nā capillaries hoʻomau ʻole i hoʻopaʻa ʻia:

He mau lua liʻiliʻi ko kēia ʻano capillaries, a i ʻole nā ​​māwae intracellular, ma waena o nā cell endothelial e hana ana i nā paia. He liʻiliʻi loa kēia mau lua a hiki i nā ʻāpana liʻiliʻi loa e like me ka wai, glucose, hormones, a me nā kinoea ke hele ma waena. Hana lākou e like me nā kiaʻi puka e hoʻokuʻu wale i nā mea i koho ʻia. ʻIke mākou i kēia ʻano capillaries i loko o kā mākou ʻōnaehana nerve, ʻili, a me nā māmā .

2. Nā capillaries fenestrated mau:

He mau puka nui ko kēia ʻano capillaries, e like me nā puka makani liʻiliʻi (`fenestrations`), ma waena o nā cell. Ma muli o kēia mau "puka makani," hiki i nā meaʻai a me nā mea ʻē aʻe i loko o ke koko ke neʻe i mua a i hope me ka wikiwiki . Ua like lākou me nā kikowaena hoʻololi paʻahana. Aia lākou ma ko mākou mau puʻupaʻa, ka ʻōpū liʻiliʻi, a me nā kelepa endocrine . No ka mea, pono kēia mau ʻōkana i ka hoʻololi wikiwiki ʻana o nā mea.

Ma waho aʻe o kēia mau ʻano ʻelua, aia kekahi ʻano ʻē aʻe i kapa ʻia ʻo "nā capillaries sinusoidal". Akā, ʻaʻole lākou e hoʻomau, he nui aʻe ko lākou mau hakahaka a me nā lua. Hiki ke ʻike ʻia kēia mau mea ma nā wahi e like me ke akepaʻa, ka spleen, nā lymph nodes, a me ka iwi iwi. Akā i kēia lā, ke kālele nui nei mākou i nā capillaries hoʻomau.

He aha ke kuleana o nā capillaries mau?

ʻO kēia mau capillaries liʻiliʻi a hoʻomau ʻia nā mea e hoʻopili ai i nā aʻa a me nā aʻa koko o kā mākou ʻōnaehana kaʻapuni.E noʻonoʻo i kēia ʻano: ua like nā aʻa me nā alanui nui e lawe ana i ke koko maʻemaʻe a piha i ka oxygen mai ka puʻuwai a i ke koena o ke kino. ʻO nā aʻa koko nā alanui e lawe ana i ke koko i hoʻohana ʻia, nele i ka oxygen, a me ke koko i hoʻopiha ʻia me ka ʻōpala i ka puʻuwai. Ma waena o kēlā mau alanui nui ʻelua, ʻo kēia mau capillaries nā alanui ʻaoʻao liʻiliʻi e hiki ai ke hoʻololi ʻia nā mea ma ka pae cellular.

ʻO kā lākou hana nui ke kōkua i ka hōʻiliʻili ʻana i nā mea like ʻole i loko o ke kino i loko o ke koko a wehe iā lākou mai ke koko a hāʻawi iā lākou i nā ʻōpū . Ua like ia me kahi lawelawe lawe.

Pehea e kōkua ai kēia mau mea i nā ʻōpū ʻē aʻe?

Kākoʻo nā capillaries hoʻomau i nā ʻōkana a me nā ʻōnaehana koʻikoʻi he nui i loko o ko kākou kino. E nānā kākou pehea:

• Lolo: I loko o ka lolo, hui pū kēia mau capillaries e hana i kahi pale pale kūikawā, i kapa ʻia ʻo "ka pale koko-lolo." Pale kēia i nā mea ʻino mai ke komo ʻana i ka lolo.
• ʻŌnaehana Endocrine: ʻO nā hormones he mau ʻelele kemika e kaohi ana i nā hana like ʻole i loko o ko kākou kino. Hoʻouna ʻia kēia mau hormones i nā ʻōkana pili ma o kēia mau capillaries.
• Nā puʻupaʻa: ʻO nā capillaries kūikawā (capillaries peritubular) i loko o nā puʻupaʻa e kōkua i ke kānana ʻana i ke koko, hana i ka mimi, a hoʻihoʻi hou i nā mea e like me ka sodium a me ka wai i loko o ke kino.
• Nā Māmā: Ke hanu mākou, hoʻohui ʻia ka oxygen a mākou e hanu ai i ke koko a hoʻoneʻe ʻia ke kalapona ʻokikene i loko o ke koko ma o kēia mau capillaries i loko o nā māmā.
• ʻōpū liʻiliʻi: Ma hope o ko mākou ʻeli ʻana i ka meaʻai a mākou e ʻai ai, kōkua kēia mau capillaries i kā mākou mau cell e omo i nā meaola mai ia mea.

He aha ka pilina ma waena o nā capillaries a me ka pale koko-lolo?

He mea kūikawā loa kēia. ʻO ke keʻena koko-lolo e pale ana i ko kākou lolo, ua hana ʻia ia me kēlā mau capillaries i hoʻomau ʻole ʻia a mākou i kamaʻilio ai ma mua. He koho nui kēia mau capillaries i ka ʻae ʻana i nā mea e komo i loko o ka lolo. ʻAe wale lākou i nā mea nui e like me ka wai a me ka oxygen e hele mai ke koko a i ka lolo, me ka pale ʻana i nā mea ʻawahia a me nā mea hoʻoulu maʻi mai ke komo ʻana i loko o ka lolo . Ua like ia me ka puka palekana no ka lolo. Mālama kēia i ka lolo mai nā ulia a me nā maʻi.

He aha ke ʻano o nā capillaries mau?

E noʻonoʻo i ka liʻiliʻi o kēia mau capillaries! ʻO ka maʻamau he 8 a 10 micrometers wale nō ke anawaena. ʻO ka micrometer hoʻokahi tausani o ka millimeter (0.001 mm). Ma kahi o ka laulā o kahi swab pulupulu! Pono kā mākou mau hunaola koko ʻulaʻula e neʻe ma waena o kēia mau capillaries i hoʻokahi faila , pēlā lākou i palupalu ai.

ʻO kēia mau capillaries hoʻomau i hana nui ʻia me ʻekolu mau ʻāpana:

1. Nā pūnaewele Endothelial: ʻO kēia nā pūnaewele nui e hana ana i nā paia o nā capillaries. Ua like ia me kahi papa o nā pūnaewele e hoʻopili ana i loko o kahi paipu.

2. ʻO ka membrane lalo: He papa hoʻomau kēia o nā ʻiʻo cell e kākoʻo ana i nā cell endothelial.

3. Nā Pericytes:He mau pūnaewele kēia i kiko ʻia a puni ka ʻaoʻao o waho o nā paia capillary. Hiki i kēia mau pūnaewele ke ʻūmiʻi, ʻo ia hoʻi hiki iā lākou ke emi. Hiki nō hoʻi kēia iā lākou ke kaohi i ke kahe o ke koko.

He aha nā maʻi e hiki ke loaʻa e pili ana i kēia mau capillaries?

ʻO ka mea pōʻino, hiki i kēia mau capillaries liʻiliʻi akā koʻikoʻi loa ke kumu o nā pilikia olakino like ʻole. Hiki i kekahi o lākou ke pili i ka genetic, ʻo ia hoʻi, ua hoʻoili ʻia mai kēlā hanauna a i kēia hanauna.

Nā kūlana i hoʻokumu ʻia e nā kumu genetic:

• ʻO ka malformation arteriovenous (AVM): Ma kēia, ua hui pū ʻia nā aʻa a me nā veins i loko o ka lolo a i ʻole ke kaula spinal, e ʻae ana i ke koko e kahe ma o nā capillaries.
• ʻO ka angiosarcoma capillary: He ʻano maʻi kanesa e ulu ana i loko o nā pūnaewele endothelial.
• ʻO ka telangiectasia hemorrhagic hoʻoilina (Osler-Weber-Rendu syndrome): He maʻi kīʻaha koko hoʻoilina kēia kahi e ulu ai nā kīʻaha koko ʻē (telangiectases) a hiki ke pahū.
• Macular degeneration: Hōʻino ʻia kahi ʻāpana o ka retina i loko o ka maka. Hiki ke hana ʻia kēia e ke kahe ʻana o ke koko mai nā capillaries.
• ʻO ka maʻi maʻi Microcephaly-capillary: Ma kēia ʻano, hiki i nā pēpē i hānau ʻia me ke poʻo liʻiliʻi ke hoʻonui ʻia nā capillaries.

Nā kūlana i hoʻokumu ʻia e nā kumu non-genetic:

ʻAʻole kēia nā kumu hoʻoilina, akā hiki ke loaʻa no nā kumu ʻē aʻe.

• Nā capillaries haki: Hōʻino ʻia nā kīʻaha koko liʻiliʻi ma lalo o ka ʻili. Hiki ke hana ʻia kēia i kekahi manawa ke ʻū nui ʻoe a luaʻi paha.
• ʻO ka maʻi leaka capillary: Hiki i kēia ke hoʻohaʻahaʻa koke i ke koko. I kekahi manawa, pono paha ka mālama ʻana i ka pilikia.
• ʻO ka spider nevus (`Spider nevus` / `spider angioma` / `spider telangiectasia`): Nā kīʻaha koko liʻiliʻi e lālā ana mai kekahi wahi, e like me nā wāwae o ka nananana. ʻIke pinepine ʻia kēia mau mea ma ka maka, ka ʻāʻī, a me ka umauma.
• ʻO nā hemangiomas ʻōhelo: ʻUlaʻula ʻālohilohi, nā kīʻaha koko i ʻike ʻia ma ka ʻili o ka ʻili.
• Vasculitis: Ka mumū o nā kīʻaha koko. Hiki i kēia ke hoʻopilikia i nā capillaries. Inā hana ʻia kēia, hiki ke loaʻa nā pilikia e like me ka pahū ʻana a i ʻole ka paʻa ʻana.

Hiki i nā pilikia me nā capillaries hoʻomau ke alakaʻi i nā maʻi koʻikoʻi ʻē aʻe?

Ke noiʻi nei nā kānaka ʻepekema i kēia, akā ua manaʻo ʻia he pili paha kekahi hemahema i ka hana o nā capillaries hoʻomau i nā kūlana e like me:

• ka maʻi o Alzheimer
• Hahau
• ka dementia vascular

Pono ka noiʻi hou aku e ʻike hou aku e pili ana i kēia mau mea.

Pehea lā e mālama ai i kēia mau kīʻaha koko liʻiliʻi?

ʻO ko kākou kuleana ka mālama ʻana i ko kākou mau capillaries, ka mea e hana ana i kahi hana koʻikoʻi i loko o ko kākou kino. Eia kekahi mau mea maʻalahi hiki iā ʻoe ke hana:

• Inā ʻoe e puhipaka, e noʻonoʻo e haʻalele . Pēlā nō hoʻi no ka hoʻohana ʻana i nā huahana paka.
• E hoʻomaʻamaʻa i kahi nohona hana . ʻO ia hoʻi nā mea e like me ka hoʻoikaika kino a me ka hele wāwae.
• E ho'āʻo e mālama i ke kaumaha olakino .
• E makaʻala i ka nui o ka waiʻona āu e inu ai.

Eia kekahi, he mea nui e kamaʻilio me kāu kauka e pili ana i nā kūlana e hoʻopilikia paha i ke olakino o kou mau kīʻaha koko a hoʻomalu iā lākou. ʻO kēia mau mea:

• Maʻi diabetes
• Ke koko kiʻekiʻe
• Kolesterol kiʻekiʻe
• Ke kaumaha

Ke kāohi ʻia kēia mau mea, he pōmaikaʻi nō hoʻi ia i nā capillaries.

Pehea e pale aku ai i nā capillaries haki ma ka maka?

ʻO kahi pilikia i loaʻa i nā kānaka he nui, ʻo ia nā capillaries liʻiliʻi e like me ke kaula ʻulaʻula e ʻike ʻia ma lalo o ka ʻili ma ko lākou helehelena. Eia kekahi mau mea e hiki ke kōkua i ka pale ʻana i kēia mau mea mai ka haki ʻana:

• E hōʻemi i ka inu ʻana i ka waiʻona.
• E ho'ōki i ka puhipaka.
• Inā loaʻa iā ʻoe kahi maʻi ʻili e like me ka rosacea, e mālama pono ʻia.
• Ke hele ʻoe i waho i ka lā, e hoʻohana i kahi sunscreen ākea e pale ai i nā kukuna UVA a me UVB .
• I ka holoi ʻana i kou maka, e holoi mālie a mālie, me ka hamo ʻole ʻana me ka ikaika.

ʻO ka mea hope loa, nā mea e hoʻomanaʻo ai

No laila, ʻo nā capillaries hoʻomau he pūnaewele o nā kīʻaha koko liʻiliʻi loa, akā he mea nui loa ia e lawe ana i ke koko, nā meaʻai, a me ka oxygen i kā mākou mau cell. E like me kā mākou i ʻike ai, aia ʻelua ʻano o kēia (continuous fenestrated a me continuous nonfenestrated) me nā hana kikoʻī.

E hoʻomanaʻo, hoʻopilikia kēia mau capillaries liʻiliʻi i ko kākou olakino holoʻokoʻa. No laila, ma ka hahai ʻana i kahi nohona olakino, hiki iā ʻoe ke mālama pono i kēia mau hoaaloha liʻiliʻi. Inā he mau nīnau a kānalua paha kāu e pili ana i kēia, mai kānalua e kamaʻilio me ke kauka.

Nā capillaries, nā capillaries hoʻomau, nā kīʻaha koko, ke kahe koko, ke olakino, nā cell endothelial, ka pale koko-lolo
