Ka waena, ahu iho ninoieo o arteries transversely striated nāʻiʻo, arteries waiwai

Mai ka weheʻana i loko o ka XVII kenekulia English kauka William Harvey ka loaʻa o ke kānāwai o ka neʻeʻana o ke koko ma na oihana a pau ma ka 'epekema, ka mea i loaʻa i ke kino i ka luna' oihana o ka lawelawe oihana mua. O aa koko, capillaries a me arteries o ke kanaka. Ka mea, i ka hookahi mall kumumanao, like i embryogenesis i hana mai kekahi germ, ahu iho - mesoderm. Ma muli o ka oko ao ma ka oihana hana ma kekahi 'ano o ka ipu, ka mea, he mau hiʻona o ka' ole. Ma keia 'atikala mākou, e kālele ana ma luna o ka mea i ho'ākāka' waiwai o na moku koko komo i loko o ka poe liilii, a me ka nui holo.

Like kūkulu arterial pa

'ōlewa, mau nō a me ka laholio paipu e hele mai i ka naau - he kanaka artery. E like me ia i ke koko holo ÿana i nā mea a pau nā loko a me nā'aʻaʻa, aeee e lawe mai ana i oxygen a me ka mahuaola: monakō koko,'amino nāʻakika, glycerol a me ka momoma nāʻakika. Ka poʻe e lawe i nā huahana o ke kelepona hele pūnao, a me ka o carbon dioxide. Ma nā ipu a pau o ka neʻe aku i arterial koko ma lalo o ka puʻuwai, a ma kekahi i lawa ke kiekie māmā. E malama i ka pono o ka artery paia e loa ikaika pono. Ka mea, i ka ekolu-ahu 'ole, a mākou e nānā i ka hou au mamuli.

maloko 'ole

Ekolu iwi o ka moku: ka mea ma waho, waena a me ka loko, i ka oko ao i wehewehe i ka mana hoʻokōʻia e ia. Ke'ī mai, ka mea ma waho, ahu iho ua haku o ka wehe connective'aʻaʻa, nā aʻalolo a hāʻule pahū wale komo iloko. Pīhoihoi, hele ma luna o ia mau mea, ke kumu o ka loli ma ka lumen o ka artery, a e loli ai i ka 'inideka o ke koko, i loko o ka moku. Ka waena, ahu iho ninoieo o arteries striated olona, a me kekahi mau he ala apuupuu Muscle'aʻaʻa. Eia ka mea, e noho i loko o nā arteries connective kaula makalii i loaʻa i ke kumuʻiʻo elastin. Manawa a hiki i ka contraction a me ka hoʻomaha a me ka muscular, ahu iho o ke koko o na moku lumen hoʻololi. Ua Ua hooponopono ma nā aʻalolo olona, o ka autonomic ko mākou hopohopo nenoaiu. Pela, ke excitation i loko o ke aloha o mahele kumu hou o arteries, a ma ka parasympathetic - hooakeaia ko lakou anawaena. Pahale loko, ahu iho wahi holo nōhie ninoieo o ka kūikawā connective'aʻaʻa - endothelium, ua he loa Kaulu, a ua hoakaka maikaʻi ana no ka pele o ke koko ana. I hiki ke ike, na papa a pau o ka arterial pa pono hana koko hoolilo hana ma lalo o ka puʻuwai, a ma kiʻekiʻe māmā.

ka mea nui arterial moku i loko o ke kanaka kino noonoo. O nā ka aorta, pulmonary a me coronary moku.

aorta

E like me ka nui loa artery o ke kino, i ka aorta mńlie mai ka ventricle hema, a ua puunaueia i ekolu lala: i ka pii aku, e pio mai a me ka iho lala. Ka mea, i ke koko o nā mea a pau i ka na nā loko a me nā'aʻaʻa. Ke manaʻo koikoi ilaila mea 120-150 mm o Hg. Art. E ku i ka hopena, mai paʻa apana o ke koko kipaku mai i ka naau, i ka waena, ahu iho ninoieo o ka ikaika arterial Muscle'aʻaʻa, hoopio ai hoi i hua'ōlelo i makemake kamakawiwoʻole, a conducive i ke koko holo. Rhythmic contractions aortic pa hiki huai ae mawaho probing lāʻau ikiʻai wale ma ka kahahānai artery o ka haʻalele na pulima oʻu. Thinning o ka Muscle, ahu iho, ka mea make o ka elasticity alakai i ke kūpono 'ana o aortic aneurysm - he nui maʻi i ho i ka hoʻoweliweli' ana i ke ola, a ma ka wanaao kahua o ka hoʻonaʻauao mai i akaka symptoms. Kēia complicates ke kakahiaka nuiʻike, a me ka maʻi hiki ke 'akomi i hoʻohana' ana i kekahi papa hana e like me ultrasound arteries.

Pulmonary holo

Bright ula kala like 'ole, paʻa kūhohonu loa me ka o oxygen a me ka mahuaola, arterial koko Pńk'pika mai o ka naau ma ka aorta. Eia hoʻomaka ka systemic holo. Eia, aie a hiki i ka kaawale ana o ka aorta i loko o ekolu lala, i ke koko kahe ana a hiki i na nā loko o nā mea a pau physiological nenoai. Aia Ua hoi liʻiliʻi, no laila,-kapa pulmonary, kaiapili, e hoʻomaka ana mai o ka ventricle akau. Mai keia hele mai i ka pulmonary artery, a hāpai nā Oe alveolar akemāmā venous koko i ua ua ohi ka luna, a malalo huamoa aa koko o ka systemic holo. E hoʻomanaʻo i loko o kaʻaoʻao'ākau o ka naau mea venous koko, ua hoʻokuʻuʻia kekahi hapa o ka i loko o ka pulmonary artery. Puʻe i loko o ka mea i loa ai kiʻekiʻe, eia nae haahaa ma mua i loko o ka aorta.

O ka wati waena, ahu iho? Oaieeia, o myofibrils artery i laumania Muscle'aʻaʻa, alternating me ka laholio puluniu kumuʻiʻo. Ma ka lala hema a me ka pono o ka pulmonary venous koko a hiki i ka ia maʻiʻaʻai kahi kinoea, e loaa hou i wahi: o carbon dioxide i hoʻokuʻuʻia i loko o ka lua o na alveoli, a loko o ke koko eiei? Oxygen ma nā lātoma a i pili i ka ÷ naehana hanu pigment - hemoglobin.

E like me 'oe ke' ike, ka pulmonary artery, e hoʻomau ana ma ka pulmonary holo, hāpai venous ke koko a hiki i ka ia maʻiʻaʻai.

coronary moku

Heart - kekahi o ka loa hiki-kino puʻipuʻi muscular kino hana rhythmically. Ka mea, ua 'oi aku i ke koko a pau o ka holoʻokoʻa kino, akā, i ka mea e pono ai o uninterrupted loaa ana mai o trophic waiwai a me ka oxygen. E lawe mai kona nui mama no hoi o ke kino i kona iho vascular nenoaiu.

Ua nā artery lala emanating mai o ka hapa mua o ka aorta kapaia u kukui. I ka waha o na moku coronary e aia ma hope pono o ka aortic kiwikā, i Aʻole 'ae i ke koko hoʻi i loko o ka ventricle hema o ka naau. Ma ka coronary oihana a pau o ka lā hiki aku ai a hiki i 500 nā lika o ke koko, i kēia hōʻike 'ana i kekahi mea kaumaha e haawe, a hoi paha a hiki i ke kahua o ke koko kokuaia a hiki i ka puu wai. Ka waena, ahu iho ninoieo o arteries muscular a me ka laholio olona, a pela i ka hooulu ana o ka atherosclerosis paha ma pinepine koke spasm e lilo elasticity. Ma ke aha ka lumen ua hoemi, a hoʻonāukiukiʻana mai o ka hapa o ka naau Muscle necrosis - myocardial infarction.

ke koko,

Mua, ua loaʻa i loko o ka arteries o ke koko ma lalo o neʻe puʻe, a ma kiʻekiʻe māmā. Ke koko, ua pili i ka cardiac kūlana: systole a me ka diastole, a me ka maʻamau vascular leo ke kaha like kokekau i 120/70 mm o Hg. Art. Ua Ua ana ma luna o ka manaʻo koikoi moʻokūʻikena o ka brachial artery. Inā i nā paia o nā arteries ololi, ua mahuahua, a me ka manaʻo koikoi, piʻi pū kā lākou leo. Oia kekahi pathological kulana kapa hypertension. Ua hiki aku i ka haawe ana o ka naau Muscle a me kona koko lako haunaele me ka pono lapaʻau hiki i ka naʻau hoouka.

Ma keia pepa ke kuka nei lakou i ka 'ole o arteries a me ka hoʻokumu hiʻona o ko lākou mau functioning i loko o ke kino o ke kanaka.
