Ua noʻonoʻo paha ʻoe i ka moʻolelo kupaianaha ma hope o ke kani ʻana o kou puʻuwai, ka pulsation āu e ʻike ai ke kau ʻoe i kou lima ma kou umauma? ʻOiaʻiʻo, i loko o ko kākou kino, aia kahi ʻōnaehana o nā kīʻaha koko, e like me kahi pūnaewele o nā alanui ma ke kūlanakauhale liʻiliʻi. ʻO kēia ka mea e lawe mai i ke ola i ko kākou kino holoʻokoʻa. ʻAe, e nānā kākou pehea e hana ai kēia mea kupaianaha i kapa ʻia ʻo ke kahe koko, a i ʻole ke kahe koko .
Pehea ka waiwai o ke koko?
Ua ʻike mākou a pau i ke koʻikoʻi o ke koko iā mākou. Akā he aha ka hana a ke koko i ko mākou kino? E noʻonoʻo, ua like ke koko me ka lawelawe lawe ʻana holomua loa i loko o ko mākou kino.
He mea kupaianaha maoli nā lawelawe a ke koko e hāʻawi ai i ko kākou kino. I ka ʻōlelo maʻalahi:
- Ke hanu kākou, lawe ʻia ka oxygen e komo ana i loko o nā māmā e ke koko i kēlā me kēia ʻāpana liʻiliʻi o ke kino, i kēlā me kēia cell.
- ʻO nā meaolaola a mākou e loaʻa ai mai ka meaʻai a mākou e ʻai ai, ʻo ia hoʻi, ka ikehu a me nā wikamina e pono ai ko mākou kino, ua hoʻolaha ʻia ma ke kino holoʻokoʻa e ke koko.
- Eia kekahi, kōkua ke koko i ka hōʻiliʻili ʻana i nā huahana ʻōpala, e like me ke kalapona ʻokikene , i hana ʻia e ka hana a ko kākou mau pūnaewele a lawe iā lākou i nā wahi i hoʻopau ʻia ai lākou mai ke kino (e like me nā māmā a me nā puʻupaʻa).
- ʻAʻole wale kēia, akā lawe pū ke koko i nā pūnaewele pale kino e hakakā ana i nā maʻi i loko o ko kākou kino a hoʻouna i nā kemika koʻikoʻi e like me nā hormones i kahi e pono ai lākou.
No laila, he mea nui ke koko no ka hoʻomau ʻana i ko kākou ola a me ka mālama ʻana i ke olakino o kēlā me kēia ʻiʻo o ko kākou kino.
ʻO ko mākou puʻuwai - he pamu kupaianaha e hana mau ana!
No ka hoʻouna ʻana i kēia koko ma ke kino holoʻokoʻa, pono ia i ka mana, ʻeā? ʻĀ, ʻo ia ka hana a ko kākou puʻuwai, a i ʻole cardiomyocyte. Ua like ia me ka pamu super e hana mau ana i ka lā a pau, ʻoiai ke hiamoe nei kākou. I kēlā me kēia manawa e paʻi ai ka puʻuwai, e pamu ʻia ana kahi koko liʻiliʻi ma ke kino holoʻokoʻa. He mea kupaianaha loa kēia ma ka awelika, e paʻi ana ko kākou puʻuwai ma kahi o hoʻokahi haneli tausani manawa i ka lā!
ʻO ka ʻōnaehana vascular - Ka Pūnaewele Alanui o ke Kino
ʻAʻole laha wale ke koko a ka puʻuwai e pamu ai ma ke kino holoʻokoʻa. He ʻōnaehana alanui kūikawā kona. Kāhea mākou i kēia ʻo ka ʻōnaehana hoʻopuni koko . Ma kēia ʻōnaehana, lawe ʻia ke koko ma o ʻekolu ʻano paipu o nā nui like ʻole i kapa ʻia he mau kīʻaha koko . E like me ke kūlanakauhale he mau alanui nui, nā alanui liʻiliʻi, a me nā alaloa liʻiliʻi.
ʻO kēia mau ʻano kīʻaha koko ʻekolu:
1. Nā aʻa koko
2. Nā aa koko
3. Nā Capillaries
E kamaʻilio kākou e pili ana i kēlā me kēia ʻano.
Nā aʻa - nā ala e lawe i nā leka mai ka puʻuwai a i ke kino
He mau kīʻaha koko nui nā aʻa e lawe ana i ke koko maʻemaʻe a piha i ka oxygen mai ka puʻuwai a i nā ʻiʻo ʻē aʻe . Hōʻike pinepine ʻia lākou me ka ʻulaʻula ma nā kiʻikuhi no ka mea he nui ka oxygen i loko o lākou (akā ʻo ka ʻoiaʻiʻo, he ʻulaʻula nā koko a pau!).
- ʻO ka aorta ka aʻa nui loa a nui e lawe ana i ke koko i waho o ka puʻuwai. Ua like ia me ka paipu nui loa e puka mai ana mai loko mai o kahi pahu wai.
- E hoʻomaka ana mai kēia aʻa nui, e like me nā lālā o kahi lāʻau, e lālā ana ia i loko o nā aʻa liʻiliʻi a hele a puni ke kino. Hoʻolako kēia mau aʻa i ke koko i nā lima, nā wāwae, ke poʻo, a me nā ʻōkana āpau o ke kino.
- He mānoanoa a ikaika hoʻi nā paia o nā aʻa koko, a he palupalu lākou no ka mea pono lākou e kū i ke kaomi a kaohi i ke kahe o ke koko ke pamu ka puʻuwai i ke koko ma ke kaomi kiʻekiʻe.
E noʻonoʻo i kēia mau aʻa e like me ka ʻōnaehana lako wai nui no ke kūlanakauhale. ʻO lākou nā mea e lawe ana i ka wai maʻemaʻe i kēlā me kēia home a me kēlā me kēia wahi.
ʻO nā capillaries - nā kikowaena hoʻololi liʻiliʻi loa
ʻAʻole hele pololei ke koko e puka mai ana mai nā aʻa i nā aʻa. Ma waena, aia kahi pūnaewele o nā aʻa koko lahilahi loa, ʻaʻole mānoanoa ma mua o kahi lauoho, e hiki aku ana i kēlā me kēia ʻāpana liʻiliʻi o ke kino, kēlā me kēia cell. ʻO kēia nā mea a mākou e kapa nei he capillaries. Ua like kēia me nā alahaka liʻiliʻi e hoʻopili ana i nā aʻa a me nā aʻa.
- He lahilahi loa nā paia o kēia mau capillaries - e pololei, hoʻokahi wale nō papa o nā cell ka mānoanoa.
- ʻAe kēia mau paia lahilahi i ka lawe maʻalahi ʻana o ka oxygen a me nā meaʻai mai ke koko a i nā ʻiʻo, a ʻae ʻia ke kalapona ʻokikene a me nā huahana ʻōpala ʻē aʻe e hoʻihoʻi maʻalahi ʻia i ke koko mai nā ʻiʻo.
- I ka ʻōlelo maʻalahi, ʻo kēia mau capillaries kahi e hana ʻia ai ka hoʻololi maoli . Ua like ia me kahi hale kūʻai liʻiliʻi, kahi e hoʻololi ʻia ai nā waiwai i mua a i hope.
He maikaʻi loa kēia pūnaewele capillary a ua ʻōlelo ʻia ʻaʻohe cell hoʻokahi i loko o ko mākou kino i ʻoi aku ma mua o hoʻokahi milimita ka mamao mai kekahi o kēia mau capillaries. Ua pālahalaha loa lākou ma ke kino holoʻokoʻa.
Nā aa koko - Nā ala e lawe ai i ke koko i hoʻopiha ʻia me ka ʻōpala i ka puʻuwai
I kēia manawa, ma hope o ka hoʻolako ʻana i ka oxygen a me nā meaʻai i nā ʻiʻo a me ka hōʻiliʻili ʻana i ke kalapona ʻokikene a me nā huahana ʻōpala mai ia mau mea, pono e hoʻihoʻi ʻia ke koko i ka puʻuwai. Hana ʻia kēlā hana koʻikoʻi e kahi ʻano kīʻaha koko i kapa ʻia he vein. Hōʻike pinepine ʻia kēia mau mea i ka uliuli ma nā kiʻikuhi no ka mea he emi ka oxygen o kēia koko.
- ʻO nā aʻa liʻiliʻi, e hoʻomaka ana mai nā capillaries, e hui mālie e hana i nā aʻa nui aʻe, kahi e lawe mai ai i ke koko i ka puʻuwai. E like me nā kahawai liʻiliʻi e hui pū ana e hana i kahi muliwai nui.
- ʻO ka maʻamau, hele ke koko me ka oxygen liʻiliʻi a me ke kalapona ʻokikene nui ma o kēia. (Akā, hoʻokahi ʻokoʻa i kēia, ʻo ia nā aa koko e lawe mai i ke koko maʻemaʻe mai nā māmā a i ka puʻuwai - ua kapa ʻia lākou he mau aa koko pulmonary. He mea paʻakikī iki ia, e kamaʻilio mākou e pili ana i kēlā ma hope).
- Ua ʻike paha ʻoe i kekahi manawa, ma kou mau lima a i ʻole kou mau wāwae, ʻike ʻia nā aʻa koko he polū ma luna o ka ʻili. He mau aʻa koko kēlā. Aia nā aʻa koko ma kahi ʻoi aku ka ʻili ma mua o nā aʻa koko.
- ʻO ke aʻa nui e lawe ana i ke koko mai ko kākou poʻo a me nā lima i ka puʻuwai ua kapa ʻia ʻo Superior Vena Cava . ʻO ka Vena Cava haʻahaʻa e lawe ana i ke koko mai ka ʻōpū a me nā wāwae . Hōʻiliʻili kēia mau aʻa nui ʻelua i ke koko haumia mai ka puʻuwai.
- He lahilahi iki nā paia o nā aʻa koko a emi iho ka elastic ma mua o ko nā aʻa koko no ka mea ke kahe nei ke koko ma o nā aʻa koko ma ke kaomi haʻahaʻa.
- Aia kekahi mea koʻikoʻi loa i loko o nā aʻa koko. A ʻo ia hoʻi nā valves.Ua like kēia me nā puka e wehe wale ana i hoʻokahi ala. Kōkua kēia mau kiwikā i ke kahe ʻana o ke koko ma kekahi ʻaoʻao wale nō, i ka puʻuwai, a pale iā ia mai ke kahe ʻana i hope. He mea kōkua nui kēia mau kiwikā i ka lawe ʻana i ke koko i luna e kūʻē i ke koʻikoʻi, ʻoiai mai nā wahi e like me nā wāwae.
Ua ʻike anei ʻoe i ka lōʻihi o kēia ʻōnaehana aʻa koko?
ʻAʻole ʻoe e manaʻoʻiʻo, akā inā ʻoe e hohola i nā aʻa koko, nā aʻa koko, a me nā capillaries a mākou i kamaʻilio ai, e ʻoi aku lākou ma mua o 60,000 mile (96,500 kilomita) ka lōʻihi ! Ua lawa kēlā e hele a puni ka honua ma mua o ʻelua manawa! ʻAʻole anei he mea kupanaha ka loaʻa ʻana o kahi pūnaewele lōʻihi o nā alanui i loko o ko mākou kino?
Ke kahe mau o ke koko a me ke kuleana o ka puʻuwai
Ma kēia ʻano, ʻaʻole e pau ke kahe ʻana o ke koko i loko o ko kākou kino no hoʻokahi kekona. Ke hoʻomau nei kēia kaʻina hana i ko kākou ala ʻana, hiamoe ʻana, holo ʻana, a me ka ʻai ʻana. ʻO ke kumu o kēia mau mea a pau, ʻo ia ka hoʻomau ʻana o ka puʻuwai. Hana ka puʻuwai ma ke ʻano he mīkini o kēia ʻōnaehana holoʻokoʻa holoʻokoʻa.
No ke aha he mea nui kēia huakaʻi koko iā mākou?
I kēia manawa ua maopopo paha iā ʻoe ke koʻikoʻi o kēia kahe koko, a i ʻole ke kaʻapuni ʻana o ke koko, i ko mākou kino.
I ka ʻōlelo maʻalahi:
- I mea e ola a hana ai kēlā me kēia ʻāpana liʻiliʻi i loko o ko kākou kino, pono e holo pololei kēia kahe koko .
- ʻAʻole hiki i kā mākou mau pūnaewele ke hana me ka ʻole o ka oxygen a me nā meaʻai, e like me ka hiki ʻole i ke kaʻa ke holo me ka ʻole o ka wahie.
- Eia kekahi, inā ʻaʻole e hoʻoneʻe ʻia nā ʻōpala, hiki ke hōʻino ʻia nā cell a make pū kekahi.
- I kekahi manawa, ke kū mai nā pilikia i loko o kēia mau kīʻaha koko, no ka laʻana, inā e ālai ʻia lākou (me nā waihona o nā mea e like me ka cholesterol) a i ʻole inā e emi ana ko lākou elasticity, hiki ke hoʻopilikia ʻia ke kahe koko a hiki ke loaʻa nā maʻi like ʻole. Hiki i kēia mau mea ke alakaʻi i nā kūlana koʻikoʻi e like me nā hōʻeha puʻuwai a me nā hahau.
ʻO ia ke kumu he mea nui ka mālama ʻana i ke kahe koko olakino no ko kākou olakino holoʻokoʻa.
ʻO nā mea nui loa e pono ai mākou e hoʻomanaʻo
No laila, i kēia manawa ua maopopo iā ʻoe ke ʻano paʻakikī, kupaianaha, a koʻikoʻi hoʻi o ke kaʻina hana o ke kahe koko i loko o ko kākou kino.
ʻO ko mākou puʻuwai, he ʻōkana liʻiliʻi, e hoʻopuka mau ana i ke koko ma o kēia pūnaewele nui o nā kīʻaha koko, e hāʻawi ana i ke ola i kēlā me kēia cell i loko o ko mākou kino. Inā e hana pono ana kēia ʻōnaehana, ua olakino a maikaʻi mākou.
No laila, he mea nui loa ka mālama ʻana i ko kākou puʻuwai a me kēia ʻōnaehana hoʻopololei koko, ʻo ia hoʻi ka hahai ʻana i nā ʻano maikaʻi e like me ka ʻai ʻana i ke olakino, ka hoʻoikaika kino, a me ka pale ʻana i ka puhipaka. No ka mea, ʻo kēia ʻōnaehana kupaianaha ka mea e ola ai kākou!
Koko , koko, puʻuwai, kahe koko, nā aʻa, nā aʻa koko, nā capillaries, oxygen, meaʻai
