Ua ʻike anei ʻoe i nā kīʻaha koko liʻiliʻi akā ikaika (Arterioles) i loko o ko kākou kino?

Ua noʻonoʻo paha ʻoe pehea e holo ai ke koko ma o ko kākou kino? Ma kēia huakaʻi e lawe ai i ke koko mai ka puʻuwai a i kēlā me kēia ʻāpana o ke kino, aia kekahi mau hui liʻiliʻi akā koʻikoʻi loa e pāʻani ana i kahi kuleana ʻike ʻole ʻia. Ua kapa ʻia lākou he `(Arterioles)`. I ka ʻōlelo maʻalahi, he mau kīʻaha koko liʻiliʻi loa kēia. I kēia lā, e kamaʻilio mākou e pili ana i kēia mau `(Arterioles)`, ka hana a lākou e hana ai, a pehea e mālama ai iā lākou i ke olakino.

He aha nā ʻ(Arterioles)`? Aia lākou ma hea?

ʻAe, e nānā mua kākou i ke ʻano o kēia mau `(Arterioles)` (i kapa ʻia ʻo `arterioles'). Ua ʻike ʻoe e kahe ana ke koko mai ko kākou puʻuwai a i ke kino ma o nā kīʻaha koko nui, ʻo ia hoʻi, nā aʻa. Ua māhele ʻia kēlā mau aʻa nui i nā kahawai koko liʻiliʻi a maikaʻi, ʻaʻole i mānoanoa e like me ka lauoho. Ua kapa ʻia lākou he `(Arterioles).` E like me nā alanui ʻaoʻao liʻiliʻi e māhele ana mai kahi alanui nui. ʻO kēia mau `(Arterioles)` nā kahawai koko liʻiliʻi a maikaʻi loa e lawe ana i ke koko i nā `(Capillaries)`. E noʻonoʻo, ua like kēia mau `(Capillaries)` me nā kikowaena hoʻololi. ʻO ia kahi e loaʻa ai i nā ʻiʻo a me nā ʻōkana o ko kākou kino ka oxygen a me nā meaʻai e pono ai lākou mai ke koko, a hoʻihoʻi ʻia nā huahana ʻōpala i loko o kēlā mau ʻiʻo i ke koko. No ke kōkua ʻana i kēia hoʻololi ʻana, ua pili pū nā aʻa liʻiliʻi loa, i kapa ʻia ʻo venules (ʻo ia nā mea e lawe ana i ke koko i ka puʻuwai), i kēia mau capillaries. No laila, ma hea kēia mau arterioles? ʻOiaʻiʻo, ma nā wahi āpau o ko kākou kino! No ka mea, pono kēlā me kēia cell a me nā ʻiʻo i loko o ko kākou kino i ka oxygen a me nā meaʻai. No laila, ua hohola ʻia kēia mau kahawai liʻiliʻi ma ke kino holoʻokoʻa e like me kahi pūnaewele. I ka ʻōlelo maʻalahi, ʻo ke anawaena o nā arterioles ma kahi o 100 a 7 micrometers. ʻO ia hoʻi, he waiwai liʻiliʻi loa ia, ma kahi o 0.30 a 0.01 millimeters. ʻO ka mānoanoa o ka paia ma kahi o 0.02 millimeters. ʻOiai he liʻiliʻi, nui loa kā lākou hana.

He aha ka hana nui a kēia mau '(Arterioles)' liʻiliʻi?

ʻOi aku ka nui o ka hana a kēia mau `(Arterioles)` liʻiliʻi ma mua o kou manaʻo. ʻO ka mea nui, ʻo ia ke kāohi i ke kahe koko a me ke kaomi koko ma loko o ko kākou kino. E noʻonoʻo wale, hana kēia mau `(Arterioles)` i 80% o ke kū'ē ʻana e kū mai ana i ka wā e kahe ai ke koko ma o ka ʻōnaehana kīʻaha koko o ko kākou kino! I nā huaʻōlelo ʻē aʻe, hoʻokele a kāohi kēia mau kahawai liʻiliʻi i ka wikiwiki a me ka ikaika o ko kākou koko e neʻe ai ma loko o ke kino, a me ka nui o ke koko e hele ana i ko kākou mau ʻiʻo i kēlā me kēia manawa. Ua ʻike anei ʻoe pehea e hana ai kēia? Loaʻa i nā paia o nā `(Arterioles)` nā ʻiʻo. Hiki i kēia mau ʻiʻo ke ʻūlū (hoʻopaʻa) a hoʻonui (hoʻonui). E like me ke kaomi ʻana i kahi paipu wai e hoʻololi i ka wikiwiki o ka wai.

• Hiki i kēia mau "(Arterioles)" ke kū i ke kaomi o ke koko e hele mai ana mai ka puʻuwai mai.
• Hiki iā lākou ke ʻomi (hoʻopaʻa) i ke koko i kona hele ʻana mai ka puʻuwai a i nā ʻāpana ʻē aʻe o ke kino. Penei ke ʻano e mālama ʻia ai ke koko koko mau a paʻa.

ʻO kekahi mea ʻē aʻe, ʻo ia ka hana ʻana ma ke ʻano he loulou ma waena o nā aʻa nui a me nā capillaries liʻiliʻi loa, ʻo ia hoʻi, hana ia e like me ke "kanaka waena". Kōkua kēia mau "Arterioles" i ka lawe ʻana i ka oxygen a me nā meaʻai mai nā aʻa nui i nā ʻiʻo ma o ia mau capillaries, a e hōʻiliʻili i nā huahana ʻōpala mai nā ʻiʻo i hope ma o nā capillaries a lawe iā lākou i nā veins, i kapa ʻia ʻo "Venules".

Pehea e kōkua ai nā ʻōpū o ke kino i ko kākou mau kino ʻē aʻe?

E like me kaʻu i ʻōlelo ai ma mua, aia nā `(Arterioles)` ma ke kino holoʻokoʻa, no laila kōkua lākou i kēlā me kēia ʻōkana o ko mākou kino. Eia kekahi mau laʻana:

• I loko o ko kākou ʻili: Hoʻopili kekahi o nā `(Arterioles)` a kōkua i ka mālama ʻana i ke koko i loko o ke kino. A laila, emi iki ko kākou anu, a noho mehana ke kino. Eia kekahi, i ka wā e hoʻonui ai (dilate) nā `(Arterioles)` i loko o ka ʻili, hoʻonui lākou i ke kahe o ke koko i ka ʻili a me nā lālā. A laila, hoʻokuʻu ʻia ka wela mai ke kino mai, a manaʻo mākou he anuanu.
• Nā puʻupaʻa : Ua pili ka glomerulus (kahi kīʻaha koko liʻiliʻi e kānana i ke koko) i loko o nā puʻupaʻa i kahi pūnaewele o nā kīʻaha koko i kapa ʻia ʻo afferent arterioles. Hiki i kēia mau mea ke hoʻonui, e ʻae ana i ka kānana ʻana o ke koko hou aku. Lawe pū nā efferent arterioles i ke koko mai ka glomerulus.
• Nā Māmā : Ke loaʻa ʻole i nā māmā ka lawa o ka oxygen , e ʻūlū nā arterioles ma laila. ʻO kēia ke kumu e hoʻohuli ʻia ai ke koko mai nā wahi me nā pae oxygen haʻahaʻa a kuhikuhi ʻia i nā wahi o nā māmā me nā pae oxygen kiʻekiʻe.
• Lolo: Hiki i nā arterioles i loko o ka lolo ke hoʻonui, e hoʻonui ana i ka nui o ke koko e kahe ana i ka lolo. ʻAe kēia i ka lolo e loaʻa ka oxygen a me nā meaʻai maikaʻi aʻe.

ʻO kekahi mau ʻoiaʻiʻo kupanaha e pili ana i nā ʻōpū o ka naʻau (Arterioles)!

Aia kekahi mau ʻoiaʻiʻo kupanaha loa e pili ana i kēia mau "Arterioles" liʻiliʻi.

ʻO kekahi, ʻo kēlā me kēia cell ʻiʻo laumania i loko o kahi arteriole he neuron ponoʻī, a i ʻole cell nerve paha. ʻO ka maʻamau, hui pū kekahi mau cell nerve e hoʻouna i nā hōʻailona i kahi puʻu o nā cell muscle. Akā ma ʻaneʻi, loaʻa pololei i kēlā me kēia cell muscle kahi leka!

ʻO ke ʻano o kēia, inā loaʻa i kā mākou ʻōnaehana nerve kahi hōʻailona e hoʻonui a hoʻemi paha i ke anawaena o kahi `(Arteriole)`, hiki iā ia ke hana pēlā me ka wikiwiki a me ka pololei loa. Kōkua kēia i ka hoʻomalu ʻana i ke koko a me ka nui o ke kahe koko me ka pololei loa. ʻO kekahi mea kupaianaha, inā e hoʻemi ʻia ke anawaena o kahi `(Arteriole)` i ka hapalua, ʻo ia hoʻi, inā pelu ʻia i ka hapalua, e emi ana ka nui o ke koko e kahe ana ma o ia mea i hoʻokahi ʻumikumamāono (1/16)! ʻO ke ʻano o kēia , ʻoiai kahi loli liʻiliʻi o ke anawaena he hopena nui ia i ka nui o ke kahe koko.

He aha nā mea i hana ʻia ai nā ʻūpā (Arterioles)?

ʻAʻole wale nā ​​​​Arterioles he mau paipu. He mau kahawai palupalu lākou, he mau paia mānoanoa i hana ʻia me nā ʻiʻo. ʻO ia ke kumu e hiki ai iā lākou ke mālama i ke koko a kāohi i ka nui o ke koko e kahe ana ma o lākou. ʻOi aku ko lākou ʻiʻo ma mua o nā aa koko. ʻO kēia no ka mea pono lākou e ʻaelike a hoʻonui i ka maikaʻi e kū i ke koko kiʻekiʻe a ka puʻuwai e pamu ai a e kāohi i ke kahe o ke koko. ʻEkolu mau papa nui o nā Arterioles: 1. Tunica intima: ʻO kēia ka papa o loko loa. Hana ʻia ia me nā pūnaewele epithelial. Kamaʻilio kēia papa me ka papa ʻiʻo ma waena. 2. Tunica media: ʻO kēia ka papa waena.

• Nā lāʻau lapaʻau e hōʻemi ai i ka mumū (no nā kūlana e like me "Vasculitis", no ka laʻana).
• He mea nui ka haʻalele ʻana i ka puhipaka a he hana pale aku hoʻi.

Nā Manaʻo No Ke Ola Kino no kahi ʻŌnaehana Arteriolar Olakino

Hiki iā ʻoe ke mālama i kou mau `(Arterioles)` olakino ma o ka hahai ʻana i kēia mau hana maʻalahi:

• E hōʻemi i ka nui o ka paʻakai āu e ʻai ai.
• E hōʻemi i nā meaʻai me ka momona kiʻekiʻe.(Nā mea e like me ka ʻaila, nā meaʻai palai, nā ʻiʻo momona)
• Hoʻoikaika kino mau. He mea maikaʻi nō hoʻi ka hele wāwae ʻana no 30 mau minuke ma ka liʻiliʻi i ka lā.
