Launch a me ka 'ole o ka nephron

Nephron mea ole wale no ka nui 'ole akā, i iaea ooieoeiiaeuiiaiʻaʻa puʻuwai pa alima. Ua ua 'aneʻi i mea na kuʻinaʻano nui o ke kahua o ka mimi. No laila, i ka 'ike e ku pono e like me ka' ole o ka nephron, a me ka mea i hana 'ia hanaʻia, e loa hoihoi' ia. Eia kekahi, i ke ano o ka functioning nephrons ke möakäka hou i nā nuances o kaʻaʻa puʻuwai'ōnaehana

Ka 'ole o ka nephron:ʻaʻa puʻuwai corpuscle

He hana hoihoi 'ia i loko o ka oo hakuʻala o ke ola i ke kanaka mea ma waena o 1 a me 1,3 ieeeea? Nephrons. Nephron - he loiloi a me mall pa alima o ka hakuʻala, a he o kaʻaʻa puʻuwai corpuscles, a no laila,-kapa loop o Henle.

Hekikai noʻaʻa puʻuwai corpuscle ninoieo o Malpighian glomerulus a me Bowman ka mea hōʻikeʻikeʻuʻuku - Shymlanskaya. No ka hoʻomaka ka mea, o kona waiwai 'ana i kumumanaʻo ana o ka mea poepoe mea nae i ka ohi ana i ka poe liilii, capillaries. Ke koko i loaʻa maʻaneʻi prinosnuyu artery - e wae 'wai koko. Koena koko loko efferent arterioles.

I ka mea hōʻikeʻikeʻuʻuku o Bowman - Shymlanskaya he o elua a lahilahi - kūloko ma a mawaho. A ina o ka pā pepa mea he maʻamau lole o squamous epithelium, me ka 'ole o ka pā pepa hewaʻiʻo hou noonoo. Ka loko lilo o ka mea hōʻikeʻikeʻuʻuku ka lānai o podocytes - mau keena e hooko aku i ka kūlana o ka hou Kānana. Ka mea, i koʻu nalo monakō koko,'amino nāʻakika a me nā waiwai, akā, pale aku i ka neʻeʻana o ka nui kumuʻiʻo nā lātoma. Pela, i loko o kaʻaʻa puʻuwai corpuscle hanaia iniiaiie mimi, i mea okoa, mai ka wai koko wale ma ka wa e kaawale aku o ka nui nā lātoma.

Nephron: ka 'ole o ka proximal tubule a me ka loop o Henle

Proximal tubule mea heʻahahui i hoʻohuiʻia kaʻaʻa puʻuwai corpuscle a me ka loop o Henle. Loko tubule he villi, a hoomahuahua i ka iauae ieiuaae o ka na lumen, hiki mahuahua i ka hou-omo lawelawe.

Proximal tubule smoothly i loko o ka lalo hapa o ka loop o Henle, a ua wehewehe aku ma ka mea uuku anawaena. Ke loop ua kuu iho la i loko o ka medulla kahi Halala puni kona iho (axis) ma ka 180 a me ka pii -ʻaneʻi hoomaka pii hapa o Henle ka loop, i ka mea iʻoi aʻe ka nui, a, me, ke anawaena. E ala loop e moe ana ma ka hola o ka nui o ka glomerulus.

Ka 'ole o ka nephron: ka distal tubules

Ka puka ana hapa o ka loop o Henle ma ka cortex hele i loko o ka ai-kapaia distal convoluted tubule. He hele mai i loko o hui 'ana me ka mea poepoe, a ma ka hui' ana me ka mea mawaho prinosnoy a me arterioles. Aia ua hana kekahi finite omo o ka mahuaola. Distal tubule hele i loko o ka pauku hope loa o ka nephron, a ma ka huli kahe ana i loko o kaʻohiʻana i ke şarkı, ke lawe loli i loko o kaʻaʻa puʻuwai pelvis.

Mea Maluna o nephrons

Ke kaumaha ma muli o ka wahi ua maheleia i ekolu papa kuhikuhi ano o nephrons:

• cortical nephrons hoolilo o ka hola 85% o ka nui o nā mea a pau mall naehana i loko o ka hakuʻala. E like me ka rula, ka mea, e aia i loko o ka pāʻaʻa puʻuwai cortex, i mea, ma ka mea, e like me ka mea e hoikeike ma kā lākou mau inoa. Nephron 'ole o kēia' ano mea iki okoa - ka loop o Henle mea uuku;
• juxtamedullary nephrons - ka hale i pono ma waena o ka lolo, a me ka cortical, ahu iho, i lōʻihi loop o Henle i komo nui i loko o ka medulla, i kekahi manawa, ae hiki aku pyramids;
• subcapsular nephrons - 'ole, a i hoʻonohonoho' ana ma lalo o ka mea hōʻikeʻikeʻuʻuku.

Ua hiki ke hoʻomaopopo i ka 'ole o ka nephron mea oo pahuhopu nei me kona hana.
