ʻO nā capillaries he kīʻaha koko liʻiliʻi - liʻiliʻi loa ia e hiki ai i kahi hunaola ʻulaʻula ke komo pono ma o lākou.

Kōkua lākou i ka hoʻopili ʻana i kou mau aʻa a me nā veins me ka hoʻoikaika ʻana i ka hoʻololi o kekahi mau mea ma waena o kou koko a me nā aʻa.

ʻO kēia ke kumu e hana nui ai nā pūnaewele, e like me kou mau mākala, ka ake, a me nā puʻupaʻa, ka nui o nā capillaries. ʻOi aku ka nui o nā kino hana metabolatic, e like me kekahi ʻano o nā mea hoʻopili, ʻaʻohe nui.

E heluhelu e aʻo hou e pili ana i ka hana o capillaries a me nā kūlana i hiki ke hoʻopili iā lākou.

He aha nā hana o capillaries?

Hoʻohui nā capillaries i ka ʻōnaehana arterial - e pili ana i nā kīʻaha koko e lawe aku i ke koko mai kou puʻuwai - i kāu ʻōnaehana venous. Aia i loko o kāu ʻōnaehana venous nā kīʻaha koko e lawe i ke koko i kou puʻuwai.

ʻO ka hoʻololi ʻana o ka oxygen, nā meaola, a me nā ʻōpala ma waena o kou koko a me nā aʻa i kū i kāu capillaries. Hana ʻia kēia ma o nā kaʻina hana ʻelua:

• Hoʻolahalaha hāhā. ʻO kēia ka neʻe ʻana o kahi mea mai kahi wahi o ke kiʻekiʻe kiʻekiʻe i kahi ʻāpana o ka haʻahaʻa haʻahaʻa.
• Pinocytosis. Kuhi kēia i ke kaʻina hana e lawe ai nā hunaola o kou kino i nā mole liʻiliʻi, e like me nā momona a me nā protein.

Hana ʻia nā paia o nā capillaries i kahi ʻulaʻula lahilahi i kapa ʻia ʻo endothelium e hoʻopuni ʻia e kahi papa lahilahi ʻē aʻe i kapa ʻia he membrane o ka hale i lalo.

ʻO kā lākou papa endothelium papa hoʻokahi, i loli i waena o nā ʻano capillaries, a me ka membrane o ka papa i lalo e hana i nā capillaries "leakier" iki ma mua o nā ʻano moku koko. ʻAe kēia i ka oxygen a me nā mole ʻē aʻe e hiki i nā hunaola o kou kino me ka maʻalahi.

Hoʻohui ʻia, hiki i nā hunaola keʻokeʻo mai kāu ʻōnaehana pale ke hoʻohana i nā capillaries e kiʻi i nā wahi o ka maʻi a i ʻole nā ​​mea ʻino ʻino ʻē aʻe.

Aia kekahi mau ʻano capillaries?

ʻEkolu ʻano capillaries. He ʻokoʻa ʻokoʻa ko kēlā me kēia mea e ʻae i ka hana i kahi ala kūʻokoʻa.

Nā capillaries hoʻomau

ʻO kēia nā ʻano capillaries maʻa mau. Loaʻa iā lākou nā wahi liʻiliʻi ma waena o kā lākou mau hunaola endothelial e ʻae ai i nā mea e like me nā kinoea, ka wai, ke kō (glucose), a me kekahi mau hormones e hele i loko.

ʻO nā capillaries mau i ka lolo ka mea ʻokoʻa.

ʻO kēia mau capillaries kahi ʻāpana o ka pale o ka lolo-koko, ka mea e kōkua i ka pale ʻana i kou lolo ma ka ʻae ʻana i nā mea pono nui e keʻa.

ʻO ia ke kumu o ka loaʻa ʻole o nā capillaries mau ma kēia wahi i nā āpau ma waena o nā hunaola endothelial, a ʻo kā lākou membrane o ka papa i lalo e mānoanoa pū kekahi.

Nā capillaries i hoʻopau ʻia

ʻO nā capillaries Fenestrated he "leakier" ma mua o nā capillaries mau. Loaʻa iā lākou nā pores liʻiliʻi, me ka hoʻohui i nā āpau liʻiliʻi ma waena o nā hunaola, i loko o kā lākou paia e ʻae ai i ka hoʻololi ʻana o nā mole nui.

ʻIke ʻia kēia ʻano capillary i nā wahi e koi ai i ka nui o ka hoʻololi ma waena o kou koko a me nā aʻa. Eia kekahi laʻana o kēia mau ʻāpana:

• ka ʻōpū liʻiliʻi, kahi e komo ai nā mea momona mai ka meaʻai
• nā puʻupaʻa, kahi i kānana ʻia nā huahana neoneo mai ke koko

Nā capillaries Sinusoid

ʻO kēia nā ʻano capillary rarest loa a "leakiest" hoʻi. ʻAe nā kapikala Sinusoid no ka hoʻololi ʻana o nā mole nui, a ʻo nā hunaola hoʻi. Hiki iā lākou ke hana i kēia no ka mea he nui nā āpau i ʻoi i ko lākou paia capillary, a me nā pores a me nā puka liʻiliʻi. ʻAʻole piha ka membrane o ka hale i lalo me nā puka ma nā wahi he nui.

ʻIke ʻia kēia ʻano capillaries i loko o kekahi mauʻaʻa, e like me nā ʻano o kou ake, pākī, a me ka iwi iwi.

ʻO kahi laʻana, i loko o kou iwi iwi, hiki i kēia mau capillary ke ʻae i nā huna koko hou e komo i loko o ke kahe o ke koko a hoʻomaka i ka holo.

He aha ka hana ke hana ʻole nā ​​capillaries?

ʻOiai heʻuʻuku nā capillaries, ʻo nā mea āpau ʻole i kā lākou hana ʻana hiki ke hana i nā ʻōuli i ʻike ʻia a i ʻole nā ​​kūlana olakino koʻikoʻi paha.

Pahu waina awa

ʻO nā stain waina Port kahi ʻano hānau hānau i hoʻokumu ʻia e ka hoʻonui ʻia o nā capillaries i loko o kou ʻili. ʻO kēia ākea e hōʻike i ka ʻili i ka ʻulaʻula a i ʻole ʻulaʻula i ke kala, e hāʻawi ana i ke ʻano i kona inoa. Ma hope o ka manawa, hiki iā lākou ke pouli ke kala a mānoanoa.

ʻOiai ʻaʻole lākou e hele i kā lākou iho, ʻaʻole pālahalaha nā stain waiona awa i nā wahi ʻē aʻe.

ʻAʻole koi nā stain waina Port i ka lapaʻau ʻana, ʻoiai ʻo ka hoʻomaʻamaʻa laser e hiki ke kōkua i mea e māmā ai ke kala.

Petechiae

ʻO Petechiae he mau wahi liʻiliʻi a pōʻai e ʻikea ma ka ʻili. ʻO lākou maʻamau e pili ana i ka nui o kahi pinhead, hiki i ka ʻulaʻula a me ka poni i ke kala, a pālahalaha i ka ʻili. Kū lākou i ka wā e kulu ai nā capillaries i ke koko i loko o ka ʻili. ʻAʻole lākou e māmā i ke kala ke kau ʻia kaomi ma luna o lākou.

ʻO Petechiae kahi hōʻailona o kahi ʻano paʻa, e like me:

• nā maʻi infectious, e like me ka ʻulaʻula, maʻi meningococcal, a me Rocky Mountain ʻike ʻia ke kuni
• trauma mai ke kanikau ʻana i ka luaʻi ʻana a i ʻole ka puʻe ʻana
• maʻi leukemia
• scurvy
• pae pae haʻahaʻa

ʻO kekahi mau lāʻau, e like me ka penicillin, hiki ke hoʻokumu iā petechiae ma ke ʻano he ʻaoʻao.

Syndrome liʻiliʻi capillary ʻōnaehana

ʻO ke systemic capillary leak syndrome (SCLS) kahi ʻano maʻamau i loaʻa ʻole ke kumu maopopo. Akā manaʻo ka poʻe loea pili paha ia i kahi mea i loko o ke koko e hōʻino ai i nā paia capillary.

Hoʻopilikia pinepine ka poʻe me SCLS i ka wā e hāʻule wikiwiki ai ke koko. Hiki ke koʻikoʻi kēia mau hoʻouka a koi aku i ka lāʻau olakino olakino.

Hele pinepine ʻia kēia mau hoʻouka me kekahi mau hōʻailona hōʻailona mua, e like me:

• paheʻe ihu
• ʻūhā
• nausea
• ʻeha poʻo
• abdominal eha
• ʻālohilohi
• pehu i nā lima a me nā wāwae
• maule ana

Mālama ʻia ʻo SCLS me nā lāʻau e kōkua i ka pale ʻana i kēia mau hoʻouka ʻana.

ʻO ka maʻi malformation Arteriovenous

Loaʻa i nā kānaka me nā maʻi malformation arteriovenous (AVM) i kahi aʻa ʻole o nā aʻa a me nā uaua e pili ana kekahi i kekahi me ka ʻole o nā capillaries ma waena. Hiki ke hana i kēia mau tangle ma nā wahi āpau o ke kino, akā ʻike pinepine ʻia i ka lolo a me ka iwi kuamoʻo.

Hiki i kēia ke kumu i nā leona e hoʻopilikia i ke kahe o ke koko a me ka lawe ʻana o oxygen. Hiki i kēia mau leona ke kumu i ke kahe ʻana i ke kaola a puni.

ʻAʻohe kumu o AVM i nā ʻōuli, no laila ʻike pinepine ʻia ʻoiai ke hoʻāʻo nei e hōʻoia i kahi kūlana ʻē aʻe. Eia nō naʻe, i kekahi mau hihia, hiki iā ia ke kumu:

• ʻeha poʻo
• ʻeha
• nāwaliwali
• nā pilikia me ka hihiʻo, haʻi ʻōlelo, a me ka neʻe ʻana
• ka hopu ʻana

He kūlana laha ʻole ʻo AVM e kū mau nei i ka manawa hānau. Hoʻomaʻamaʻa maʻamau i ka hana ʻoki ʻana a i ʻole pani ʻana i ka leona AVM. Hiki i ke kauka ke kōkua i ka mālama ʻana i nā ʻōuli, e like me ka ʻeha a ʻeha poʻo poʻo hoʻi.

Syndrome malformation Microcephaly-capillary

ʻO ka microcephaly-capillary malformation syndrome kahi ʻano laha ʻole e hoʻomaka ma mua o ka hānau ʻana.

ʻO nā kānaka me kēia ʻano he poʻo liʻiliʻi ko lākou a me ka lolo. Ua hoʻonui lākou i nā capillaries e hoʻonui i ke kahe o ke koko kokoke i ka ʻili, kahi e hiki ai i nā ʻulaʻula ʻulaʻula i ka ʻili.

Hiki i nā hōʻailona ke hoʻohui pū me:

• lohi hoʻopololei ulu
• ka hopu ʻana
• paʻakikī i ka ʻai ʻana
• neʻe ʻokoʻa
• ʻokoʻa nā hiʻohiʻona hiʻohiʻona, hiki ke hoʻopili i ka lae e holoholo ana, ke alo a puni, a me ka ulu lauoho ʻokoʻa
• lohi ka ulu ʻana
• pōkole a liʻiliʻi paha ke kino
• manamana a me manamanalima abnormalities, me maoli liʻiliʻi a i ʻole absent kui

Hoʻokumu ʻia ka Microcephaly-capillary malformation syndrome e ka hoʻololi ʻana i kahi ʻāpana kikoʻī i kapa ʻia ʻo STAMBP ʻāpana Hiki i nā hoʻololi ʻana i kēia ʻāpana ke hopena i ka make ʻana o nā hunaola i ka wā o ke kūkulu ʻana.

Hiki i ka mālama ʻana no kēia ʻano ke hoʻopili i ka hoʻonāukiuki ʻana - keu hoʻi ma ke kani a me ka paʻi - ke hoʻopaʻa ʻana e mālama i ke kū ʻana, a me ka lāʻau anticonvulsant lapaʻau no ka mālama ʻana i ka hopu ʻana.

Ke laina lalo

ʻO nā capillaries nā kīʻaha koko liʻiliʻi e hana nui i ka hoʻomohala ʻana i nā ʻano mea like ʻole ma waena o kou kahe koko a me nā aʻa. Nui a hewahewa nā ʻano capillaries, kēlā me kēia me ka ʻokoʻa ʻokoʻa a me ka hana.
