Pehea e neʻe ai ke koko ma kou kino? (Ke Kahe ʻana o ke Koko a me ka ʻŌnaehana Kaʻapuni) E ʻike kākou ma ke ala maʻalahi!

Ua kū anei ʻoe a noʻonoʻo pehea e holo ai kēia mea i kapa ʻia ʻo ke koko a puni ko mākou kino me ka ʻole o nā pilikia? ʻAʻole anei he mea kupaianaha? I kēlā me kēia kekona e paʻi ai ko mākou puʻuwai , hoʻoneʻe kēia pamu liʻiliʻi i ke koko ma o kahi ʻōnaehana o nā paipu ma o ko mākou kino. ʻO kēia ka mea a mākou e kapa nei ʻo ' Circulatory System' . Ua like kēia mau paipu me nā paipu laholio palupalu e lawe ana i ke koko i kēlā me kēia ʻāpana liʻiliʻi o ke kino. ʻAe, no laila e kamaʻilio kākou e pili ana i kēia me nā kikoʻī hou aku?

No ke aha he mea waiwai nui ke koko iā kākou?

He ʻāpana koʻikoʻi maoli ke koko o ko kākou ola. E noʻonoʻo wale, ʻo kēia koko ke kōkua i kēlā me kēia ʻāpana liʻiliʻi a me nā ʻiʻo i loko o ko kākou kino e ola a hana. Eia nā mea nui e hana ʻia me ke koko:

• Lawe ke koko i ka oxygen a me nā meaʻai koʻikoʻi i nā ʻiʻo i loko o ko mākou kino, e like me ka lawe ʻana mai i ka meaʻai a me ka mea inu i ko mākou mau home.
• Kōkua pū ke koko i ka wehe ʻana i ke kalapona ʻokikene i makemake ʻole ʻia a me nā huahana ʻōpala ʻē aʻe e hōʻiliʻili ana i loko o nā ʻiʻo a hoʻokuke aku iā lākou mai ke kino, e like me ka lawe ʻana i ka ʻōpala i loko o kou home.
• No laila, no kēia mau mea a pau, he mea nui ke koko no ka hoʻomau ʻana i ko kākou ola a me ka mālama ʻana i nā ʻāpana a pau o ko kākou kino i ke olakino .

Ke maopopo nei iā ʻoe ke koʻikoʻi o ke koko?

ʻEkolu ʻano nui o nā kīʻaha koko!

ʻEkolu ʻano nui o nā kīʻaha koko i loko o ko kākou kino e kōkua i ka hoʻoneʻe ʻana i kēia koko. E like me nā alanui, he mau alanui nui, nā alanui liʻiliʻi, a me nā alanui ʻaoʻao.

1. Nā ʻaʻa koko - nā kīʻaha koko e lawe ana i ke koko maʻemaʻe mai ka puʻuwai mai

ʻO nā aʻa koko nā kīʻaha koko e lawe ana i ke koko momona i ka oxygen (i hōʻike pinepine ʻia ma ke ʻulaʻula ma nā kiʻi) a me nā meaʻai mai ko kākou puʻuwai a i nā ʻiʻo ʻē aʻe a pau o ke kino. E noʻonoʻo iā ia me he pamu wai lā ka puʻuwai, a ua like nā aʻa koko me nā paipu nui e lawe ana i ka wai maʻemaʻe mai kēlā pamu a i ka māla holoʻokoʻa.

• Hoʻomaka kēia ʻōnaehana arterial me ka aorta, ke kīʻaha koko nui loa e puka mai ana mai ka puʻuwai. Ua like ia me ka paipu nui loa e puka mai ana mai kahi pahu wai nui.
• Lawe kēia i ke koko waiwai i ka oxygen mai ka puʻuwai a i nā ʻiʻo a pau o ke kino.
• I kou neʻe ʻana aku mai ka puʻuwai aku, māhele ʻia kēia mau aʻa i mau lālā, e lilo mālie ana i mea liʻiliʻi. E like me ka māhele ʻana o ka muliwai nui i mau ʻauwai liʻiliʻi.

No laila, ʻo ka hana nui o nā aʻa ka hoʻolaha ʻana i ke koko maikaʻi ma ke kino holoʻokoʻa .

2. Nā Capillaries - nā kikowaena hoʻololi liʻiliʻi loa

He pūnaewele o nā kīʻaha koko liʻiliʻi a lahilahi loa nā capillaries. ʻO kēia nā mea e hoʻopili ai i nā kīʻaha koko nui ʻelua, nā aʻa a me nā veins. E noʻonoʻo iā lākou he moʻo o nā alanui ʻaoʻao liʻiliʻi ma waena o nā alanui nui ʻelua.

• He lahilahi loa nā paia o kēia mau capillaries, e like me ka ʻupena.
• ʻAe kēia mau paia lahilahi i nā mea maikaʻi e like me ka oxygen a me nā meaʻai e hele mai ke koko i nā ʻiʻo, a me nā mea makemake ʻole e like me ke kalapona ʻokikene a me nā huahana ʻōpala i hana ʻia i loko o nā ʻiʻo e hoʻi i ke koko . Ua like ia me ke kūkaʻi ʻana i nā waiwai ma kahi mākeke.

ʻOiaʻiʻo, ʻo kēia hoʻololi koʻikoʻi ma ka pae cellular o ke kino e hana ʻia ma o kēia mau capillaries liʻiliʻi. He liʻiliʻi loa lākou, ʻoi aku ka lahilahi o kekahi o lākou ma mua o ko mākou lauoho! Akā, he nui ka hana a lākou e hana ai, ʻeā?

3. Nā aʻa koko - nā kīʻaha koko e lawe ana i ke koko haumia i ka puʻuwai

ʻO nā aʻa koko he mau kīʻaha koko e lawe ana i ke koko i pau i ka oxygen, a i ʻole ke koko "lepo" (i hōʻike pinepine ʻia me ka uliuli ma nā kiʻi) mai nā ʻiʻo o ko mākou kino a hoʻi i ka puʻuwai. Ua like ia me kahi ʻōnaehana o nā paipu e hōʻiliʻili i ka wai i hoʻohana ʻia a hoʻihoʻi iā ia i ka pahu.

• ʻO kēiaLawe nā kīʻaha koko i ke koko haʻahaʻa i ka oxygen a kiʻekiʻe i ke kalapona ʻokikene mai nā ʻiʻo o ke kino i ka puʻuwai.
• I ka hoʻokokoke ʻana aku o kēia mau aa koko i ka puʻuwai, hui pū lākou a lilo i mea nui. E like me ka hui pū ʻana o nā kahawai liʻiliʻi e hana i muliwai nui.
• ʻO ka mea hope loa, lawe mai kahi aʻa nui i kapa ʻia ʻo `superior vena cava` i ke koko mai ke poʻo a me nā lima i ka puʻuwai. Pēlā nō, lawe mai kahi aʻa nui i kapa ʻia ʻo `inferior vena cava` i ke koko mai ka ʻōpū a me nā wāwae i ka puʻuwai.

No laila, ʻo ka hana nui o nā aa koko, ʻo ia ka hoʻihoʻi ʻana i ke koko me nā huahana ʻōpala e hōʻiliʻili ana i loko o ke kino i ka puʻuwai a kuhikuhi iā ia no ka hoʻomaʻemaʻe ʻana .

ʻEhia ka nui o kēia ʻōnaehana aʻa koko ma mua o kou manaʻo?

I kēia manawa hiki iā ʻoe ke ʻike i ke ʻano paʻakikī o ka ʻōnaehana o nā aʻa, nā veins, a me nā capillaries i loko o ko mākou kino. Ua ʻike anei ʻoe ʻo ka ʻōnaehana aʻa koko holoʻokoʻa - ʻo ia hoʻi, nā aʻa āpau, nā veins, a me nā capillaries i hui pū ʻia - ʻoi aku ma mua o 60,000 mile ka lōʻihi ! Ke kahe mau nei ko kākou koko ma o kēia ʻōnaehana nui. Ua like ia me kahi pūnaewele o nā alanui ma ke kūlanakauhale, me nā kaʻa e hele ana i mua a i hope i nā manawa a pau. No laila, ʻo ka mea e kōkua ana i ka pamu ʻana i kēia koko a pau ma ke kino holoʻokoʻa, ʻo ia ko kākou puʻuwai . ʻO ia ke kumu ma hope o kēia kaʻina hana holoʻokoʻa.
