Ke koko,

Ke koko, - i ka puʻe i loko o nā ipu koko. Ole ia, he mea hiki ole i ke hoʻokō 'ia i ka manaʻo o ka metabolic keʻano o ka hanaʻana i loko o ke kino nā'aʻaʻa. Mahalo iā ia, ke koko kolo ana ma ka circulatory nenoaiu.

Ke koko, ua hana i loko o ka artery, capillary, niioaaonoaaiii - ma venous capillaries a - i loko o na aa koko.

Eia kekahi, he mea ka osmotic puʻe o ke koko, e hilinaʻi nui ma luna o ka lehulehu o ka mea pōhaku paʻakai. Kona waiwai mea nō kāu koe hale lio. Akā,ʻo ka ka palena haʻahaʻa loli hiki luku ulaula koko keena. No ka neurohumoral rula hooponopono o ka osmotic puʻe kuleana hou glands a me nā puʻupaʻaʻelua.

Ma mea, pehea nui e ka arterial ke koko, e loli ai:

- mana o na contractions o ka naau;

- i ka nui o ke koko e kipaku aku ia lakou i kekahi manawa i ka wa a kela mea keia mea ka mea i hahai ana ka mea mamuli o kekahi ka ho'ēmiʻana;

- ka ia'ku i ka moku paia (ʻike ākea) hoomaopopo ana i ka neʻe koko;

- i ka helu o Kal no pa alima o ka manawa hookama.

Secondary aʻe i alakaʻi ai i ke koko, - ka mea, o ka helu a me ka (viscosity). No hoi, i ke koena unuhi i loko o ka puʻuwai o ka abdominal lua a me ka thoracic lua, i kupu ana no i ka neʻe 'ana i ka hanu.

ʻO kā mākou ke koko, ka hana i ka wā hoemi hema ventricle (systole). Pela ka mea, kipaku mea i ka ia manawa ma kahi o 70 ml o ke koko. Ma na capillaries a me nā moku uuku, e like me na dala i kekahi manawa, hiki ole kiʻi ma. Ke aorta, ma muli o ia kona elasticity, aole i lalau mai, ka poʻe ke hoala mai ia, a systolic ke koko. Ma kānaka (ola) mua ma mua o 16 makahiki, e make i ka 110 a hiki i 130 mm o Hg. Art.

Ma diastole - ke kakali ma waena o contractions o ka hema a me ka akau ventricles - ka lalau paia o na arteries nui, a me ka aorta hoʻomaka e emi. Pela, kipaku aku la lakou i loko o ka capillaries koko. A me kona puʻe paka ua ma ka pau ana o diastole i loko o ka aorta ua kuu iho la i ka 90 mm o Hg. Art, a me ka nui-pepa paia arteries -. 70 mm o Hg. Art. Ke hookaawale iwaena o systole a me ka diastole ua ike ia e ke kanaka i loko o ka palapala o ka lāʻau ikiʻai wale.

Ua oi aku ka mamao mai ka moku a hiki i ka puu wai koko, ka mea ma lalo o ka'aloʻahiʻa maloko. Mua, ka luna helu Hōʻike ka systolic ka puʻuwai a me ka lua, haʻahaʻa - no ka diastolic.

I nui arteries mea kiekie ma ka liʻiliʻi arterioles. Ma ke hoʻololi i ka capillary moe ke koko, emi iho, oi hina i loko o ka aa koko, a hiki io aiee i loko o ka puha aa koko ia ihoiho.

Ana ia mea technicallyʻaʻole loa oluolu i loko o na aa koko a me capillaries. No laila, ua hookolokoloia mai ai au i ka manaʻo koikoi waiwai ma luna o ke kumu o kona manao paa ana ma o ka arteries.

Hana o kona maʻamau hilinaʻi ma luna pehea ke kanaka e ola ana, i kana hana, a he kanaka helehelena. Me ka makahiki, i ka nui o ka puʻe loli. A me ka mea maoli i ahuia kuu mea naʻau stress, physical hana. Ia manawa, o ka 'âlapa, kanaka, ka poe i mau hana ana i ka hana kāohi, a malia paha e emi ai.

Systolic ke koko, i na keiki me ka nānā 'ana i ka haʻilula 80 + 2a, a like hoʻi - keia mea i ka makahiki (ma ka makahiki).

Nā maomeka e ola ma ke kino a me ka pāʻana i ka nui o ka puʻe, ae ia e hoʻi i ka maʻamau ma hope o nīnūnē fluctuations like me ka hopena o ka 'ehaʻeha o stress a physical hana.

Inā ka mea, e uhaʻiʻia, aia no he paakiki loli i loko o kona keu aku, alaila, kamailio e pili ana i hypertension, a ilalo, a laila ka mea, ke hele mai i ka hypotension.

Ma mau, i kekahi kanaka i ike i ko lakou koko, i ka maʻamau. A me kekahi haiahū kūmau ma kekahi ala e hiki aku e malama i ke pretext no ka hele ana i ke kauka no ka mea, o kumu e i keia anakahi huapalapala. No ka laʻana, i ka maʻi o ka infectious, naau, ma ka hihia o kaʻapu kōheoheo pinepine ia lŘlŘ hypotension. A me ka hakuʻala maʻi, endocrine haunaele - hypertension.
