Capillaries: i ka ho'ākāka 'ana

Inā ka artery a me Vienna, pakahi, e hali ana i ke koko mai o ka naʻau, a me ka ia, i na ipu nui, na capillaries - keia mea he manao maalea loa kou circulatory Tube me ke anawaena o ka 5-10 microns. A me na aa koko a me arteries, ma ka haawi ana o māhuaola i ka aeee i mai e komo i loko o ke kinoea e loaa hou mai keʻano o ka hanaʻana ma waena o lākou, a me ke koko, ke papa ia a hiki i ka capillaries like wale. Ka mua wehewehena no i ka Italia nä känaka 'epekema M. Malpighi, a i ka 1661. haawi aku ia i ka ho'ākāka' ana ma waena o loulou arterial a me venous moku. Mua ia, William Harvey wānana i ko lakou ola.

Ke 'ole a me ka nui o na capillaries

Mau moku uuku i kaha like kokekau ka ho ma kekahi nā loko. Ka nui o ia hiki i ka lumen o i ka 30 microns, a me ka loa ololi - 5 microns. He oluolu ke eʻoiaʻiʻo i ample koko capillaries ma na pauku ma ka lumen o ka Tube hoalaala ia me kekahi mau papa o endothelial keena, akā, i ka huna uuku nahā i, ahu iho ua hanaʻia oʻelua wale nō hoʻokahi paha keena.

Capillary moe, venules, arterioles

Koko ua kuhikuhi 'ana i ka naʻau ma nui moku, a lakou i ke aa koko. Capillaries kekahi, ma ke koko aa koko venules - ka mea liilii loa like eiiiiiaiou. Ka mea i hanaʻia i loko o kekahi mau wahi capillary pili 'o Randy, i kapaʻia he capillary moe, a merge i loko o ka aa koko.

Functioning me he hookahi pa alima, capillary moe hooponopono kūloko koko lako, ka'aʻaʻa pono halawai ma ka nui o ka mahuaola. Ka moku lawe ana i ke koko a hiki i ka naʻau, i ho'ākāka 'ia me ka artery. Capillary loaʻa ke koko mai ka artery ma ka arteriole - uuku ma mua o ka mea, i ka moku.

Arterioles ma ka circulatory'ōnaehana e pākuʻi mua i ka capillaries. Ma ke kahua o ka arteriolar ai manamana ai capillaries i loko o ka pā pōhaku o na moku koko e ke aupuni 'apo Muscle aeee i maopopo hoikeia, a me ka hana ana o ka sphincter.

Oihana o ka capillary endothelial

capillary endothelium mea lawa permeability no ka wehe aʻe ma waena o ke koko a me ka kino nā'aʻaʻaʻano o ka waiwai. No laila, i ka mea i hana i na capillaries, o ka hoolilo ana o ka mahuaola a me metabolic huahana.

Ka wai a me ka 'ona ua hoʻopau i loko o ia, mea maʻamau oluolu, e hele ana oukou ma ka ipu pā ma nāʻaoʻao. Akā, ma ka ia nā polokina, a me ke koko keena noho maloko o ka capillaries. I hanaʻia i loko o ke ola ana o ke kaʻina hana huahana i kekahi, ma ke koko ke'ākeʻakeʻa mai, e hoolilo ia lakou i ka wahi o ka excretion mai ke kino. Pela, ke capillary - i ke keʻena integral hapa o nā nā'aʻaʻa o ke kino, ho okumu i nui vascular aʻeo ka hoʻolele ', interconnected i aikane oe hui' ana me ka halepaahao hale.

Kēlā wā i kēia wā hakakino nui paha eʻoi aku ka nui e eiei? Ma endothelial keena. Ma keia hihia, e hoolilo ia e hoʻohana 'ia kekahi ka hopu keʻano o ka hanaʻana - endocytosis a kuʻi nukeliu - exocytosis. Ma hoʻoʻino keʻano o ka hanaʻana i loko o ke kino e e capillaries, ia mea hapa o ka'ōnaehana paleʻea paneʻano papa hana.

Physiologists i ka hiki e hoopaa i keia hiʻona adventitial functioning hehee wale a ana i ka ipu koko a me ka capillaries i hoakakaia like kūikawā aeee hiki ia oe menemene.

Ua Ua hoi ea ae ia lakou iho endothelial capillary pā i ka kekahi elasticity a me ka contractility hiki a me ka hiki ke hoʻololi i ka nui o ka lumen. Kekahi psychologists paipai i ka mea i kapa mau ai ike pōkole-makahiki ka ho'ēmiʻana o endothelial aeee i loko o ia mau wahi ma kahi o ka adventitious keena. Pathological na kumu e like me loa'ā, a me ka hawewe hiki i ka dilation o na capillaries mea 3 manawa kiʻekiʻe ma mua o maʻamau. Eia, e like me ka rula, aia no he nui emi i loko o ka uku o ke koko, i leie aku ka mea i loaa i loko o ka capillary moe i loko o ka wahi o ka poino.
