Circulatory kahua

Ka'ōnaehana o kekahi holoholona kino ninoieo o ka pūʻulu circulatory nā loko, a i 'ole i loko o ke koko holo. E like me ka hopena o kona maʻamau hana ua hoolilo pono nui o ka o oxygen a me ka mahuaola, hormones a me ka paʻakai e like me nā pōʻino hehee wale. Eia hou, i ke koko holo'ōnaehana hanaʻia ka lua o ka papa. Ua paa ia ia ka keena a me ka neoneo, e loaa hou mai e kaili mai na wahi a pau o ke kino i hanaia maloko o carbon dioxide. A luna 'pukapuka ma i pono ai no ka functioning o ka meaola waiwai i hoopakeleia ma nā mea a pau o kona' oihana, i hana mai i nā ipu a pau, me ka naau a me ke koko iho.

System ana, haawi aku i nā mea a pau nā loko ka mahuaola, ma muli o ka ha awina o myocardial Muscle. Ia mea, ae hana i ka hana o ka EII ni, pumping koko ma kiʻekiʻe māmā. Ke kumukuai o keia mea, ua like me he umikumamakahi mau mika kekona päkahi. I ka contractions o ka naau Muscle ma loli puʻe i, ka mea i kapaia o excessive. Ua mea ma luna o ka lewa. Excessive stress ma ka 'inikua hoʻomaʻamaʻa ua kapaia koko. Kona huahelu hoʻomaka me ka lākou o ka 'Aʻohe like a like me ka nui a hiki i ka lewapuni ka puʻuwai. I loko o kekahi minuke o ka hana i hanaia i ka quiescent moku'āina o ke kino, i ka naau EII ni ma kekahi 3,6 nā lika o ke koko ma ka mea e malama i ka maloko anakahi uila hua. Ke koko, i kona i kā mākou waiwai i ka manawa o ka kivila mai o ka ka ho'ēmiʻana (systole). I ka myocardial hoʻomaha (diastole), ka mea maloko anakahi uila paka ua e 'Aʻohe.

Ke circulatory nenoaiu o kona pukapuka? Aaeaao koko pele. Ua hele ma na ipu, he wai ka i ka pa apŘ o 1,06 nā huna no cubic kenimika i hoʻolaunaʻia ma. Koko ua neʻe ma ka'ōnaehana, me arteries a me ka nui aa koko. Mau moku lala pinepine ae la oia, a i nā emi iho ka nui i ka mea uuku capillaries. Ke koko ke hele i ka mämä holo i ua hāʻawiʻia ma ka naʻau pāpana. Ma holo ana o ka wai i ololi ka na hoʻopilikia a me ke anawaena moku lumen. Arteries i hala aku ma ke koko kahe ma kanalima kenimika no kekona. Ma na aa koko o kona waiwai, he iwakalua knm / mau. Nā capillaries i ka loa haʻahaʻa mämä holo 'ana i kā lākou uuku anawaena. He emi mai o mau millimeters no kekona. I ka wa i uhi pū kēia manaʻo koikoi lāʻau ikiʻai wale i loko o capillaries.

Ka buke o ka circulatory'ōnaehana mea nui oi aku ma mua o ka nui i loko o ke koko o ke kino. Ua Ua piha me ka wale hoʻokahi kanahā tausani. Ma keia mea, he kumu. Inā ana ai ka haohao ana i ka hoopai nui ke koko kahe i na nā loko, ka mea, e neʻe ana ma ke ala e hiki aku akau.

Anatomia o ka naʻau na moku a me ke koko mau Ply e leie aku i ke koko i loko o ka triangle, i ka loaʻa o nā maʻiʻaʻai, Muscle, myocardium a me ka akepaʻa. Ma keia hihia, no ka mea māhuaola maalo ae la oia ma na arteries a me capillaries, a noho i loko o na halepaahao o ke kino o ke kanaka, he hoʻonui i ka maʻamau functioning o ke kino. I ka ho okumu i ka cardiac Muscle a me ka vascular pathologicalʻike manaʻo ana circulatory maʻi. Mau maʻi puʻuwai nā:

- huʻi rheumatic kuni type;

- ischemic mai o ka naau Muscle;

- maʻi i pū 'oe me ka hoomahuahua i loko o ke koko,;

- rheumatic maʻi naʻau maʻi;

- 'aʻe' ana o ka pulmonary holo ana o ke koko;

- cerebrovascular maʻi;

- maʻi o na capillaries a me arteries;

- maʻi o aa koko, lymphatic na moku a me nā aka wahi;

- nā moku a me ka naau maʻi.

Circulatory'ōnaehana, e like me kona ola kino ua pili loa kiaʻi ma ka 'inikua' epekema. Ke kumu no keia mea i ka noho lakou malaila ana helu ikepili i kau aku i ka naau a me ka vascular mai i loko o ka wahi mua i loko o ke ao nei ma ka hua'ōlelo o ka palaho.
