He aha ka ʻōnaehana venous?

ʻO nā uaua kahi ʻano o ke kīʻaha koko e hoʻihoʻi i ke koko deoxygenated mai kāu mau mea i hoʻi i kou puʻuwai. ʻOkoʻa kēia mai kāu mau aʻa, e hāʻawi i ke koko oxygenated mai kou puʻuwai i ke koena o kou kino.

Hōʻiliʻili ʻia ke koko Deoxygenated e kahe ana i loko o kou mau uaua i loko o nā kīʻaha koko liʻiliʻi i kapa ʻia he capillaries. ʻO nā capillaries nā kīʻaha koko liʻiliʻi loa i kou kino. Hele ka oxygen ma loko o nā paia o kou capillaries i kou mauʻaʻaʻa. Hiki i ke kalapona kalapona ke neʻe i kāu capillaries mai ke aʻa ma mua o ke komo ʻana i kāu mau uaua.

ʻO ka ʻōnaehana venous e pili ana i ka pūnaewele o nā veins e hana e hoʻihoʻi i ke koko deoxygenated i kou puʻuwai.

ʻĀina o ke kino

Hana ʻia nā paia o kou veins i ʻekolu mau papa like ʻole:

• Tunica externa. ʻO kēia ka papa waho o ka paia o ke aa, a ʻo ia ka mānoanoa pū kekahi. ʻO ka hapa nui i hana ʻia me nā pūnaewele hoʻopili. Aia i loko o ka tunica externa nā kīʻaha koko liʻiliʻi i kapa ʻia ʻo vasa vasorum e hāʻawi i ke koko i nā paia o kou veins.
• Pākaukau ʻo Tunica. ʻO ka pāpāho tunica ka papa waena. He lahilahi a loaʻa ka nui o nā collagen. ʻO Collagen kekahi o nā mea nui o nā mea hoʻopili.
• Tunica intima. ʻO kēia ka hohonu o ka papa. He papa hoʻokahi ia o nā hunaola endothelium a me kekahi mea hoʻopili. Aia i kēia papa i kekahi manawa nā kiwikā o ke ala hoʻokahi, keu hoʻi i nā aa o kou mau lima a me kou mau wāwae. Pale kēia mau kiwikā i ke kahe ʻana o ke koko i hope.

Nā ʻano o nā uaua

Hoʻokaʻawale pinepine ʻia nā uaua ma muli o ko lākou wahi a me nā hiʻohiʻona ʻokoʻa a i ʻole nā ​​hana.

Pulmonary a me nā ʻōnaehana ʻōnaehana

Kolo kou kino i ke koko ma nā ala ʻelua ʻelua i kapa ʻia ka ʻōnaehana ʻōnaehana a me ke kaapuni pulmonary. Hoʻokumu ʻia nā veins i ke kaapuni i loaʻa iā lākou i:

• Nā uaua koko. Lawe ke kaapuni pulmonary i ke koko deoxygenated mai kou puʻuwai i kāu mau māmā. Ke oxygenate kou mau māmā i ke koko, lawe ka kaapuni pulmonary iā ia i kou puʻuwai. ʻEhā mau uaua pulmonary. Kū hoʻokahi lākou no ka mea lawe lākou i ke koko oxygenated. Hāpai nā veins ʻē aʻe āpau i ke koko deoxygenated wale nō.
• ʻUnaehana ʻōnaehana. Lawe ke kaapuni ʻōnaehana i ke koko deoxygenated mai ke koena o ke kino i kou puʻuwai, kahi e komo ai i ka puni pulmonary no ka oxygen. ʻO ka hapa nui o nā uaua he ʻōnaehana ʻōnaehana.

Nā uaua hohonu a me nā ʻāne nui

Hoʻokaʻawale hou ʻia nā veins ʻōnaehana e like me kekahi:

• Nā aa koko hohonu. Loaʻa kēia i nā mākala a i ʻole nā ​​iwi. ʻO ka tunica intima o kahi aa hohonu ka paepae hoʻokahi ala e pale ai i ke kahe o ke koko i hope. Hoʻopili pū nā mākala kokoke i ka aa hohonu e mālama i ke koko i mua.
• ʻO nā uaua koko kiʻekiʻe. Aia kēia mau mea i ka momona momona ma lalo o kou ʻili. Hiki i ka tunica intima o ke aʻa ʻoi loa ke loaʻa i kahi kiwikā hoʻokahi ala. Eia nō naʻe, me ka ʻole o kahi mākala kokoke no ka compression, makemake lākou e neʻe lohi i ke koko ma mua o ka hana o nā aa hohonu.
• Pili nā veins. Kuhi pinepine ʻia ke koko mai nā veins superficial i loko o nā veins hohonu ma o nā veins pōkole i kapa ʻia nā veins pili. Hiki i nā valves i kēia mau uaua ke kahe o ke koko mai nā veins superficial i kāu mau aa hohonu, akā ʻaʻole ka ala ʻē aʻe.

Kiʻi ʻōnaehana Venous

E hoʻohana i kēia kiʻikuhi 3-D mākaʻikaʻi e ʻimi i ka ʻōnaehana venous.

ʻO nā kūlana hea ka hopena o ka ʻōnaehana venous?

Hiki i nā ʻano he nui ke hoʻopili i kāu ʻōnaehana venous. ʻO kekahi o nā mea maʻamau e hoʻopili pū me:

• Trombosis o ka aa hohonu (DVT). Hoʻokumu kahi hāpala koko i kahi aa hohonu, i ka manawa maʻamau i kou wāwae. Hiki ke hele huakai kēia i kou mau māmā, e hoʻoulu ai i ka pulmonary embolism.
• Trombophlebitis superficial. An vef superficial vein, ʻo ka maʻa mau i kou wāwae, hoʻomohala i kahi hui koko. ʻOiai hiki i ka clot ke hele i kekahi manawa i kahi aa hohonu, e hoʻoulu ana i ka DVT, ʻoi aku ka nui o ka koʻikoʻi o ka thrombophlebitis ma mua o ka DVT.
• ʻO nā veins varicose. ʻO nā veins superficial kokoke i ka ʻili o ka ʻili ʻikea pehu. Hana ʻia kēia i ka wā e wāwahi ai nā kiwikā hoʻokahi a i ʻole nāwaliwali o nā paia, e ʻae ana i ke kahe o ke koko i hope.
• ʻO ka lawa ʻole o ka venous. Hōʻuluʻulu ke koko i nā veins superficial a hohonu o kou mau wāwae ma muli o ka hana kūpono ʻole o nā kiwikā o ka ʻaoʻao hoʻokahi. ʻOiai e like me nā veins varicose, ʻo ka lawa ʻole o ka venous hoʻomau pinepine i nā ʻōuli, e like me ka ʻili o ka ʻili ākea a me nā ulcer i kekahi mau hihia.

He aha nā hōʻailona o kahi ʻano ʻino?

ʻOiai hiki ke loli ākea nā ʻōuli o kahi ʻano ʻino, kekahi o nā mea maʻamau i:

• pehu a pehu paha
• palupalu a ʻeha paha
• ʻenaʻena e mahana i ka hoʻopā
• kahi ʻāʻā a i ʻole ʻāno it sensation

Kūleʻa kēia mau hōʻailona i kou mau wāwae. Inā ʻoe e ʻike i kekahi o kēia mau mea a hoʻomaikaʻi ʻole lākou ma hope o kekahi mau lā, e hoʻopaʻa i kahi manawa me kāu kauka.

Hiki iā lākou ke hana i kahi kiʻi kiʻi kiʻi. I kēia kaʻina hana, hoʻopiʻi kāu kauka i ka ʻokoʻa make i loko o kāu mau uaua e hana i kahi kiʻi X-ray o kekahi wahi.

Nā ʻōlelo aʻoaʻo no nā veins ola

E hāhai i kēia mau ʻōlelo aʻoaʻo e hoʻomau i ka ikaika a me ka hana pono ʻana o kou mau paia aʻa.

• E loaʻa i ka hoʻoikaika kino mau i ka neʻe ʻana o ke koko ma o kou veins.
• E hoʻāʻo e mālama i kahi kaupaona olakino, kahi e hōʻemi ai i kou makaʻi i ke kiʻekiʻe o ke koko. Hiki i ke kahe koko kiʻekiʻe ke hoʻonāwaliwali i kou mau uaua ma muli o ke kaomi i hoʻohui ʻia.
• Hōʻalo i nā wā lōʻihi o ke kū a noho ʻana paha. E hoʻāʻo e hoʻololi i nā kūlana i nā manawa āpau i ka lā.
• Ke noho i lalo, pale i ka hele wāwae i kou mau wāwae no ka manawa lōʻihi a i ʻole hoʻololi pinepine i nā kūlana i kū ʻole kekahi wāwae i luna no kahi manawa lōʻihi.
• Ke lele nei, inu nui i ka wai a hoʻāʻo e kū i luna a hoʻolōʻihi pinepine i ka hiki. ʻOiai e noho ana, hiki iā ʻoe ke wili i kou kuʻekuʻe wāwae e hoʻoikaika i ke kahe o ke koko.
