ʻO ke aʻa vs.

ʻO nā aʻa nā kīʻaha koko e kuleana no ka lawe ʻana i ke koko waiwai oxygen mai ka puʻuwai i ke kino. ʻO nā aa koko nā kīʻaha koko e lawe i ke koko haʻahaʻa i ka oxygen mai ke kino a hoʻi i ka puʻuwai no ka reoxygenation.

ʻO nā aʻa a me nā uaua ʻelua ke ʻano nui o ke kino o nā kīʻaha koko. ʻO kēia mau moku nā kahawai e hāʻawi i ke koko i ke kino. ʻO lākou kahi o nā ʻōnaehana paʻa ʻelua o nā paipu e hoʻomaka a hoʻopau i ka puʻuwai. ʻO kēia ʻōnaehana o nā paipu ʻo:

• Pulmonary. ʻO nā kīʻaha pulmonary nā aʻa e lawe i ka oxygen-koko maikaʻi ʻole mai ka ventricle ʻākau o ka puʻuwai i nā akemāmā. Hāpai nā veins pulmonary i ke koko waiwai piha i ka atrium hema o ka puʻuwai.
• ʻŌnaehana. ʻO nā kīʻaha ʻōnaehana nā aʻa e lawe i ke koko momona o ka oxygen mai ka ventricle hema o ka puʻuwai i nā pūnaewele i nā ʻāpana āpau o ke kino. A laila hoʻihoʻi lākou i ke koko maikaʻi ʻole o oxygen ma o nā veins i hoʻi i ka atrium pono o ka puʻuwai.

He aha nā ʻano aʻa like ʻole?

Aia he ʻekolu ʻano aʻa. Hoʻokomo ʻia kēlā me kēia ʻano ʻekolu kapa: ma waho, ma waena, a ma loko.

• Nā aʻa elastis ua kapa ʻia kekahi o nā aʻa a me nā aʻa ʻauʻau. He mānoanoa waena ko lākou i hiki iā lākou ke kīloi i ka pane ʻana i kēlā me kēia pā o ka puʻuwai.
• Nā ʻaʻa muscular (hāʻawi) he pae waena. Kuhi lākou i ke koko mai nā aʻa elastis a me nā lālā i nā moku kūʻē. Hoʻopili kēia mau moku i nā aʻa liʻiliʻi a me nā arterioles.
• Arterioles ʻo ia ka mahele liʻiliʻi loa o nā aʻa e lawe i ke koko mai ka puʻuwai. Kuhikuhi lākou i ke koko i loko o nā pūnaewele capillary.

He aha nā ʻano ʻokoʻa o nā uaua?

ʻEhā ʻano o nā uaua:

• Nā aa koko hohonu Aia i loko o nāʻiʻo muscle. Loaʻa iā lākou kahi aʻa pili kokoke.
• ʻO nā uaua koko kiʻekiʻe kokoke i ka ʻili o ka ʻili. ʻAʻohe o lākou aʻa kaulike.
• ʻO nā veins pulmonary lawe i ke koko i hoʻopiha ʻia me ka oxygen e nā māmā i ka puʻuwai. Loaʻa i kēlā me kēia māmā nā ʻāpana o nā uaua pulmonary, kahi ʻākau a hema.
• ʻUnaehana ʻōnaehana Aia ma ke kino holoʻokoʻa mai nā wāwae a hiki i ka ʻāʻī, me nā lima a me ke kumu. Hāpai lākou i ke koko deoxygenated i ka puʻuwai.

Kākoʻo artery a me nā uaua

E hoʻohana i kēia kiʻikuhi 3-D mākaʻikaʻi e ʻimi i kahi aʻa.

Anatomia o nā uaua a me nā aʻa

Hana ʻia nā paia o nā uaua a me nā aʻa i ʻekolu papa.

• Ma waho. ʻO Tunica adventitia (tunica externa) ka papa waho o kahi kīʻaha koko, me nā aʻa a me nā uaua. ʻO ka hapa nui o nā collagen a me nā olonā uila. Hiki i kēia mau olonā i nā veins a me nā aʻa e hoʻolōʻihi i kahi nui palena. Kūpono lākou e maʻalahi a mālama i ka paʻa ma lalo o ke kaomi o ke kahe o ke koko.
• Waena. Kapa ʻia ka papa waena o nā paia o nā aʻa a me nā veins i ka pāpaho tunica. Hana ʻia ia i nā mākala mānoanoa a me nā olonā uila. Mānoanoa kēia papa i nā aʻa a me ka lahilahi o nā uaua.
• Loko ʻO ka papa o loko o ka paia kīʻaha koko i kapa ʻia ʻo tunica intima. Hana ʻia kēia papa i ka fiber elastis a me ka collagen. Hoʻololi ke kūlike ʻole i hoʻokumu ʻia i ke ʻano o nā kīʻaha koko.

ʻAʻole like me nā aʻa, loaʻa nā valves i nā uaua. Pono nā mākia i nā valves e mālama i ke kahe o ke koko i ka puʻuwai. He mea nui nā valesa theses i nā wāwae a me nā lima. Kaua lākou i ka umekaumaha e pale aku i ke kahe o ke koko.

ʻAʻole pono nā aʻa i nā valves no ka mea ʻo ke kaomi o ka puʻuwai e hoʻomau i ke kahe o ke koko ma o lākou i hoʻokahi ala.

ʻO ka ʻōnaehana cardiovascular

ʻO ka ʻōnaehana cardiovascular kahi ʻōnaehana paʻa o nā moku i kapa ʻia nā aʻa, nā uaua, a me nā capillaries. Pili lākou āpau i kahi pauma muscular i kapa ʻia ka puʻuwai. Mālama ka ʻōnaehana cardiovascular i ka neʻe mau ʻana a me ka kaohi o ke koko e hāʻawi i nā meaola a me ka oxygen i kēlā me kēia cell i loko o ke kino. Hana ia i kēia ma o nā mile mile o nā capillaries ma waena o nā aʻa a me nā aa.

• Nā ʻauamo. Hāpai nā aʻa pulmonary i ke koko haʻahaʻa oxygen mai ka ventricle ʻākau o ka puʻuwai i nā akemāmā. Lawe nā aʻa ʻōnaehana i ke koko oxygenated mai ka ventricle hema o ka puʻuwai i ke koena o ke kino.
• Nā uaua Hāpai nā veins pulmonary i ke koko oxygenated mai nā akemāmā a i ka hema hema o ka puʻuwai. Lawe nā ʻōnaehana ʻōnaehana i ke koko haʻahaʻa-oxygen mai ke kino a i ka ʻaoʻao akau o ka puʻuwai.
• Nā capillaries. ʻO nā capillaries ka mea liʻiliʻi a nui loa o nā kīʻaha koko. Pili lākou ma waena o nā aʻa (kahi e lawe aku ai i ke koko mai ka puʻuwai) a me nā uaua (e hoʻihoʻi i ke koko i ka puʻuwai). ʻO ka hana mua o nā capillaries ka hoʻololi ʻana o nā mea, e like me ka oxygen, ma waena o ke koko a me nā aʻa kiko.
• Puʻuwai. ʻEhā keʻena o ka puʻuwai: ka atrium ʻākau, ventricle ʻākau, atrium hema, a me ventricle hema. Hāʻawi ka puʻuwai i ka ikaika e hoʻopuni i ke koko ma o ka ʻōnaehana cardiovascular.

ʻO ka lawe lawe ʻana

Hāʻawi ʻia nā meaola a me nā oxygen i kēlā me kēia cell i kou kino ma o ka ʻōnaehana puni. Hoʻopili ka puʻuwai i ke koko oxygenated i kāu mau pūnaewele ma o nā aʻa. Hoʻomaʻemaʻe ia i ke koko i hoʻopau ʻia i ka oxygen mai kou mau pūnaewele ma o nā uaua.
