Ọrụ na Ọdịdị nke ahụ nephron

Nephron abụghị naanị isi Ọdịdị kamakwa ọtọ gbasara akụrụ unit. Ọ bụ ebe a na-kasị mkpa nkebi nke guzobere mmamịrị. Ya mere, ihe ọmụma ndị na-anya dị ka ihe owuwu nke nephron, na ihe na ọrụ ya rụrụ, ga-akpali nnọọ mmasị. Ọzọkwa, e ji mara nke ịrụ ọrụ nephrons ike dokwuo anya nuances nke gbasara akụrụ usoro

Ọdịdị nke ahụ nephron: gbasara akụrụ corpuscle

Ọ bụ na-akpali na na tozuru okè akụrụ nke onye ahụ dị mma bụ n'etiti 1 na 1.3 ijeri nephrons. Nephron - a ọtọ na bughi unit nke akụrụ, nke bụ gbasara akụrụ corpuscles na-akpọ akaghị nke Henle.

Ọ baghị uru gbasara akụrụ corpuscle mejupụtara Malpighian glomerulus na Bowman si Capsule - Shymlanskaya. N'ihi na a mmalite na ọ bụ uru arịba ama na a bọl bụ n'ezie a collection of obere capillaries. Blood ọkọkpọhi site ebe a prinosnuyu akwara - na-ẹdụk plasma. Balance ọbara ewepụtara efferent arterioles.

The Capsule nke Bowman - Shymlanskaya mejupụtara abụọ Ibé akwụkwọ - esịtidem na mpụga. Ma ọ bụrụ na elu mpempe akwụkwọ bụ ihe nkịtị na-akpa ákwà nke squamous epithelium, Ọdịdị nke dị n'ime mpempe akwụkwọ kwesịrị ọzọ ntị. The n'ime akụkụ nke Capsule kpuchie podocytes - na mkpụrụ ndụ ndị na-emezu ọrụ nke onye ọzọ na iyo. Ha na-atụ uche glucose, amino asịd na ndị ọzọ bekee, ma gbochie ije nke nnukwu protein ụmụ irighiri. N'ihi ya, na gbasara akụrụ corpuscle kpụrụ isi mmamịrị, nke dị iche na plasma naanị site enweghị nnukwu ụmụ irighiri.

Nephron: Ọdịdị nke ahụ proximal tubule na akaghị nke Henle

Proximal tubule bụ ihe agabiga mbara igwe nke na-ejikọ ahụ gbasara akụrụ corpuscle na a akaghị nke Henle. Inside tubule nwere villi, nke na-amụba ngụkọta nke ebe nke esịtidem lumen, si otú amụba re-absorption arụmọrụ.

Proximal tubule were were n'ime n'ala akụkụ nke akaghị nke Henle, nke e ji obere n'obosara. The loop na-lowered n'ime medulla ebe ehuda gburugburu ya axis site 180 degrees na ọdọk - ebe a na-amalite na-arịgo akụkụ nke Henle si loop, nke nwere a ukwuu ibu na, ya, na dayameta. Ebili loop ụgha dị larịị nke glomerulus.

Ọdịdị nke ahụ nephron: na distal tubules

Ọwụwa akụkụ nke akaghị nke Henle na cortex aga n'ime ndị na-akpọ distal convoluted tubule. Ọ na-abịa na kọntaktị na a obi ụtọ na na kọntaktị na mpụga prinosnoy na arterioles. E na rụrụ a nwere oke absorption nke nri. Distal tubule-aga ná nkebi ikpeazụ nke nephron, nke n'aka nke aga n'ime ikpokọta tube, na ụgbọelu ọmụmụ na ndị gbasara akụrụ pelvis.

nhazi ọkwa nke nephrons

Dabere na ebe a na-ekewa atọ isi ụdị nephrons:

• cortical nephrons mejupụtara ihe dị ka 85% nke ngụkọta nke niile bughi nkeji na akụrụ. Dị ka a na-achị, ha na-emi odude na elu gbasara akụrụ cortex, nke bụ, n'eziokwu, dị ka ọ pụtara ìhè site na aha ha. Nephron Ọdịdị nke a ụdị bụ ubé dị iche iche - akaghị nke Henle bụ obere;
• juxtamedullary nephrons - dị owuwu ndị dị nnọọ n'etiti ụbụrụ na cortical oyi akwa, nwere ogologo akaghị nke Henle na banye n'ime nnọọ n'ime ndị medulla, mgbe ụfọdụ, na-eru pyramid;
• subcapsular nephrons - Ọdịdị, nke na-ndokwa ozugbo n'okpuru Capsule.
