Na systemic holo - he 'enekinia, masterpiece

E hiki anei ia oe ke manao o ka hale i loko o i i piha oi huikau hookiokio aku'ōnaehana me ka nui waiwai wai smoothly transporting ka wai, ka ai, ka oxygen, a lawe aku oe i neoneo? Eia hou, e hiki no ia lakou iho, e imi ia a me ka ulu, adapting i ka loli i loko o ka hale i nāʻohe lakou iho. Kēia 'enekinia' ole makemake i ka manaʻo mahalo o na kanaka a pau.

Akā mākou circulatory nenoaiu Ua hiki hoi ke oi. Ua regulates kino ana wela, neʻe i ka nui helu o kekahi mau hormones i lawe nui 'ike i nā mea a pau keena, hoonohonoho i ka palekana i ka pathogens. Kēia mea ulana pukapuka, He pono'ōlewa a me ka palupalu, no laila ia mea hiki ke hoʻokemuʻana i nā puʻu huapalaoa a me flex me ke kino. E ka nana i keia masterpiece i pau.

Ka 'ole o ke kanaka circulatory'ōnaehana

I ka waenakonu o ka circulatory'ōnaehana mea he puha kino - i ka naau, i mea e like me ka EII ni noke EII ni ke koko i loko o ka paʻa loop, oia hoi o ka moku.

Ka a pau'ōnaehana Ua maheleia i mau eiiiiiaiou:

• Pulmonary holo. vascular'ōnaehana e kuhikuhi pu ana i ka naau a me ka ia maʻiʻaʻai. Hoʻomaka ka p ÷ ai i loko o ka ventricle akau, i ka pau ana o ka mea moe ma ka atrium hema. Ua pili wale no na ia maʻiʻaʻai.

• He nui kaiapili o ke koko holo. Ua originates ma ka aorta a me ka welau ma ka atrium akau.

Nui holo no kona moku, e like me ka mea pervades i ke kino holoʻokoʻa.

Heart me ke kōkua o nā lonikū paia ua maheleia i mau apana. Kēlā me kēia no kēia mau wahi ua i puunaueia i loko o nā halves ma ke kumu o papamoe i pohā, ho okumu i ka ventricle a me ka atrium.

Koko mua komo i ka papa kuhikuhiE moku o ke kino - ka aorta. E möakäka hou aorta ua maheleia i na moku uuku, a me ke koko komo ka artery o ka systemic holo. Ua arteries lala aku, a hele aku i loko o ka arterioles a me capillaries. Ke anawaena o ka capillaries ka loa haʻahaʻa - ka hola 10 microns. Kēia 'o ia hoʻi i ka ula koko keena, hāpai i oxygen i na keena e hele ma na capillaries i kekahi manawa. Nā paia o nā ipu capillary mau loa lahilahi - komo o wale he hookahi ahu iho la ka aeee, akā, ka mea, 'aʻole i hiki ole i ke kokuaia mai e māhuaola i na nā'aʻaʻa aia i loko o ka hapa wai o ke koko (wai koko). Ka poʻe o nā'aʻaʻa i loko o capillaries pū i hiki i carbon dioxide a me ka metabolic nā huahana i noi aku ana, mai ke kino.

Nā capillaries i ka uuku loopy Muscle, ma ka mea o ka a lakou i hiki mana i ke kahe o ke koko maalo ae la oia ma ia mau mea, e hālāwai me ka pono o ka puni nā'aʻaʻa. I ka koko haʻalele i nā capillaries, e komo i ka microscopic aa koko - venules. Venules hou coalesce i loko o aa koko, koko ma luna o ia mau e kahe ana i ka systemic holo, hoi mai ana i ka naau. Ma na aa koko o ke koko, mea haʻahaʻa ma mua i loko o ka arteries, akā, na lumens o aa koko hou.

Pehea i ka mea ku pono neʻeʻana ua lako pono?

Mahalo i ka maikaʻi loa ka hoʻololiʻana:

• ke kiaha-hoʻokino kiwikā e pale aku i ke koko kahe mai o ka naau ma lalo o ka aoao o ka umekaumaha.

• ka hana o skeletal nāʻiʻo, a oOeEIAOO ka pono kaulike aa koko, e hookuke koko ma ka kekahi-ala kiwikā i loko o ka olelo ana o ka naau.

• Kūloko puʻe i loko o ka pahu a me ka abdomen i ha a loli aʻe kōkua na aa koko, e EII ni ke koko i loko o ka atrium akau.

I ka venous kiwikā no ka mea kumu (hāpai keiki, hereditary aaiaoe predisposition, obesity a loihi loa) mai i hana pono, ka loaa koko a me ka aa koko pehu nei ma lalo o ka nohona kiwikā. Keia ano ua ike like varicose aa koko.

Ke systemic holo lākou e hoʻopakele i oxygen a me ka lolo keena. No laila, i ka lolo koko holo ua lawe mai ma ka ia kanawai me nā mea a pau'ē aʻe nā loko. Inā ka venous outflow mai o nā ipu lolo mea pilikia, a laila, loaʻa nō pōniuniu, a headaches.

Surprisingly, o ka ka hoʻokōʻana o ka kanaka circulatory'ōnaehana mea no ke kiekie ua hiki i maha no kekahi minuke, ma kahi o 5 nā lika o ke koko ae ma ka naau, a me ka marathon o ma kahi o 35 nā lika kela minuke.

E like me 'oe ke' ike i ko kakaou Mea maoli nui akamai, kona hihia ka lima - ka systemic holo - Ua admirable!
