Neʻe ma ka ipu koko, koko 'ohua' ka mahuaola, oxygen, a i carbon dioxide, ka pale 'ana i ke kino e ku e pathogens, e hōʻoiaʻiʻo ka homeostasis o ka maloko kaiapuni.

No ka moku nā arteries, capillaries a me aa koko. Ka mea, hoakaka i ke koko alahele i loko o ke kino. He aha ka ke koena unuhi o ka artery aa koko? Aia i loko o ke kino a me nā hale, a me ka mana hoʻokō. E mākou huli ia i loko o au mamuli.

Ke artery oko, mai na aa koko: o ka 'o

Arteries - na ipu i i ke koko kahe mai o ka naʻau i nā'aʻaʻa a me nā loko. Ka nui loa artery i loko o ke kino, ua kapaia ka manawa "aorta". Ua hele mai 'ana mai o ka naau. Ma ka arteries i ke koko ma lalo o neʻe kiʻekiʻe puʻe. E hānai iā ia, kūpono 'ole o nā pā. Ka mea, he poe ekolu papa. Ka loko, a ma waho hana connective'aʻaʻa a me ka meakino - o Muscle olona. Manawa a hiki i kēia 'ole, i kēia mau kīʻaha, ua hiki o ka hohola ana, a pela ke hoole aku i ke kiʻekiʻe ke koko.

Ka 'ole o ke aa koko mea okoa, mai ka' ole o ka arteries? Mua o nā ipu a pau o kekahi 'ano e lawe aku i ke koko, mai na nā loko a me nā'aʻaʻa i ka naau. Ma hope o ka hele ana ma nā mea a pau na keena a me nā loko, ka mea, ua paʻa kūhohonu loa me ke kalapona'okikene lua, i lawe mai i ka malamalama.

Kekahi mea nui ninau - keia mea i ka likeʻole ma waena o ka 'ole o ka artery paia a me aa koko. Ka hope i ka thinner Muscle, ahu iho, Ua hoi emi laholio. E like me ke koko kahe ana i loko o aa koko ma lalo o hōʻemi iki puʻe, kā lākou stretchability mea,ʻaʻole like nui.

I ka nui o ke koko, i loko o nā ipu o ka acee? Iuo oeiia hōʻikeʻano o ka kahe ana ke koko. I ka arterial koko me ke koa, kuu ka pulsating pūnāwai. Ua he ulaula e like me oxygenated. Akā, me ka venous - ia penei he kali kahawai, a i ka uliuli. Ua Ua nānā 'ia e ka nui nui o ka o carbon dioxide.

Hapanui aa koko lumen mea he hana kūikawā eke kiwikā e pale ai i ke koko o ka neʻeʻana i loko o ke ku pono ana i ka ao ao.

capillaries

He aha ka ka okoa arteries mai aa koko, ua ike. E mākou e lohe ai i ka mea liilii loa ipu koko - capillaries. Ka mea i hana i ka kūikawāʻano o ka uhi ia'aʻaʻa - endothelium. Ua ua lawe ma pūnao ma waena o interstitial loli a me ke koko. Manawa a hiki i keia he mea kekahi ana, e loaa hou o ke kinoea.

Artery haalele ana i ka naau, mai hemo mai i loko o capillaries i mea kūpono i kēlā me kēia halepaahao o ke kino, merging i venules. Ka la mahope, i ka huli, ua pili i ka nui o na moku. Ka mea, i kapaʻia aa koko, a i kekahi hapa o ka naau. Ma keia ana koko capillaries hele pāʻani i mau manamana nui o ka hui 'ana ma waena o ke koko oihana mua a me nā keena o ka mea a pau meaola.

I ka holo ana o ke koko ma na moku

He aha ka ka okoa arteries mai aa koko, a hōʻike i keʻano papa hana o ke koko. Ma contraction o ka naau Muscle me ke koko max pahu i loko o ka artery. Ka nui o ia mau mea - ka aorta, ke manaʻo koikoi i hiki 150 mmHg. Art. Ka capillaries ua kekahi hoemi ia i ka 'ilikai 20. Ka puha venous puʻe mea ka palena haʻahaʻa, a dala i 3-8 mm o Hg. Art.

He aha ka i ka leo a me ke koko,?

Ma ka mea maʻamau ke ano o ke kino i nā kīʻaha a pau i loko o ka undervoltage kulana - leo. Inā ka leo ua mahuahua, i ka ipu koko hoʻomaka i ka pilikia. Ua hiki aku i ka mahuahua ka puʻuwai. A lohe o keia ano i ka pilina paʻa lawa, aia no he kulana kapaia hypertension. E hoole lengthy decompression kaʻina - hypotension. Ua o kēia mau maʻi, ua noho pilikia loa. I mea i loko o ka hihia mua i vascular ano hiki ke alakai i ka hoʻohuikau o kona ano hoopono, a ma ka lua o ka - ka mea hōʻemi o ke koko lako hou i nā loko.

Summing i: kaʻokoʻa arteries o aa koko? Kēia mau 'ole o ka pā, ka mea imua o ka nohona kiwikā, i ka wahi e pili ana i ka naʻau, a me ka mana hoʻokō.
