Ama-Capillaries ase-Peritubular: Ake sifunde ngalaba 'basebenzi' abancane abasezinso zethu!

Sonke siyazi ukuthi izinso zethu zihlunga imfucuza emizimbeni yethu bese ziyikhipha njengomchamo . Kodwa uke wezwa yini 'ngezisebenzi' ezincane ezingemuva kwalo msebenzi omkhulu? Namuhla sikhuluma ngohlelo olulodwa olukhethekile lwemithambo yegazi, i-'Peritubular Capillaries'. Nakuba igama lingase lizwakale liyinkimbinkimbi kancane, insizakalo eziyinikezayo emizimbeni yethu iyamangalisa futhi ibalulekile.

Ayini ngempela ama-Peritubular Capillaries?

Kalula nje, lezi ziyinethiwekhi yemithambo yegazi emincane kakhulu ngaphakathi kwezinso zethu. Zisakazeke njengolwembu lwesicabucabu. Zitholakala eduze kwama-nephron, amayunithi okuhlunga ayinhloko ezinso.

Umsebenzi wazo oyinhloko ukuhlunga imikhiqizo engcolile ezinso ngenkathi zimunca izakhamzimba ezisawusizo emzimbeni zibuyele egazini . Lokhu kusho ukuthi izinto ezifana ne -glucose , ama-amino acid, kanye namaminerali ahlukahlukene azilahleki emchameni, kodwa kunalokho zimuncwa emzimbeni ngalezi ziteshi ezincane. Zisiza futhi ekulawuleni amazinga oketshezi emzimbeni futhi ziguqule amanzi amaningi kanye nemikhiqizo engcolile ibe umchamo.

Ake sibheke amanye amaqiniso ambalwa ngalezi ziteshi ezincane:

• Ama-Peritubular Capillaries angenye yezinhlelo ezintathu eziyinhloko zama-capillary ezinso. Amanye amabili yi-Glomerular Capillaries kanye ne-Vasa Recta.
• Igazi ligeleza kule nethiwekhi yeziteshi ngengcindezi ephansi kakhulu, yingakho uketshezi nezakhamzimba kungaphinde kuthathwe kalula.
• Laba bafana nomhloli onekhono. Bakhetha futhi bagcine lokho okubalulekile emzimbeni kanye nokuthi yikuphi ukungcola okudingeka kususwe.

Yimiphi imisebenzi eyinhloko yalezi ziteshi ezincane?

Ama-capillary ase-peritubular ayingxenye ebaluleke kakhulu ohlelweni lwethu lomchamo. Lezi ziteshi ezincane zisiza lonke uhlelo, oluhlanganisa izinso, isinye , kanye ne-urethra, ukuthi lusebenze kahle.

Nazi ezinye izinto ezenziwa uhlelo lomchamo ukuze lugcine ibhalansi emzimbeni wethu:

• Ilawula izinga lama-electrolyte egazini.
• Ikhiqiza i-hormone ebizwa ngokuthi i-erythropoietin, esiza ekukhiqizeni amaseli abomvu egazi.
• I-pH yegazi, okungukuthi, isimo sayo se-acidity/alkaline, igcinwa ezingeni elifanele.
• Amanzi angadingekile kanye nemikhiqizo engcolile ikhishwa emzimbeni njengomchamo.

Manje ake sibone ukuthi le nqubo yokuhlunga yenzeka kanjani ngaphakathi kwezinso. Cabanga ngayo njengefektri eyenzeka ngezinyathelo eziningana.

1. Isinyathelo sokuqala: Igazi lingena ezigidini zamayunithi amancane okuhlunga abizwa ngokuthi ama-nephron ezinso.

2. Isinyathelo 2: Ama-capillary ase-peritubular aqondisa leli gazi esihlungini esikhethekile esibizwa ngokuthi i-glomerulus. Lesi sihlungi sibamba uketshezi, izinhlayiya ezincane, kanye nemikhiqizo engcolile. Kodwa sivumela izinto ezinkulu nezibaluleke kakhulu njengamaseli egazi namaprotheni ukuthi zidlule esihlungini ngaphandle kokulimala.

3. Isinyathelo Sesithathu: Manje isipikha sethu, ama-capillary ase-Peritubular, siyaqala ukusebenza. Amunca amaminerali abalulekile, izakhamzimba, namanzi avela oketshezini oluhlungiwe abuyele egazini.

4. Isinyathelo sokugcina: Uketshezi lokugcina olungafuneki kanye nemikhiqizo engcolile kukhishwa emzimbeni njengomchamo.

Wazi kanjani ukuthi kunenkinga ngama-Peritubular Capillaries akho?

Noma yisiphi isimo esilimaza izinso singalimaza nalezi ziteshi ezibucayi. Uma ubona noma yiziphi izinguquko emchameni wakho, kungaba uphawu lwenkinga ngezinso noma lezi ziteshi.

Ngezansi kunezinye izimpawu okufanele uzinake kakhulu.

Yiziphi izimo ezithinta ama-capillaries e-peritubular?

Lezi ziteshi ezibucayi zingonakaliswa yizimo ezahlukene zezokwelapha.

• Isifo sezinso esingamahlalakhona : Lesi yisimo lapho izinso zilahlekelwa khona kancane kancane ikhono lazo lokuhlunga imfucuza. Uma zingelashwa, izinso zingase zingasebenzi kahle ngokuphelele.
• I-Hydronephrosis: Isimo lapho umchamo ungakwazi ukuphuma khona ezinso ngenxa yokuvaleka kwendlela yomchamo, okubangela ukuba izinso zivuvuke.
• I-Pyelonephritis: Sivame ukuyibiza ngokuthi 'ukutheleleka kwezinso'. Kuwukutheleleka kwezinso okubangelwa amagciwane noma igciwane. Lokhu kungaba yingozi futhi uma kungelashwa ngokushesha.
• Ukuvaleka komchamo: Umchamo ungavaleka ngenxa yezimo ezinjengamatshe omchamo, izimila, noma ukwanda kwe-prostate emadodeni, okubangela ukuthi umchamo uphindele ezinso.

Uma ama-capillary e-peritubular onakele ngenxa yalezi zimo, ukusebenza kwawo kahle ekuhlungeni igazi kuyehla. Lesi simo sivame ukubonakala kubantu abanesifo sezinso esingamahlalakhona, i-lupus nephritis, kanye nesifo sezinso se-polycystic.

Uzigcina kanjani izinso zakho kanye nalezi ziteshi ezincane ziphilile?

Ukuze ugcine izinso zakho kanye nalezi ziteshi ezincane ziphilile, udinga ukunakekela impilo yakho iyonke. Kunezinto ezimbalwa ezilula ongazilandela ukuze wenze lokhu.

• Gwema imikhiqizo kagwayi ngokuphelele. Ukubhema kulimaza izinso ngokuqondile.
• Phuza amanzi amaningi usuku lonke. Lokhu kuzosiza izinso zakho ukuthi zenze umsebenzi wazo ngendlela efanele.
• Yidla ukudla okunempilo nokulinganiselayo. Faka imifino nezithelo eziningi ekudleni kwakho.
• Lawula isisindo sakho. Ukukhuluphala ngokweqile kuyimbangela enkulu yesifo sezinso.
• Uma unesifo sikashukela noma umfutho wegazi ophakeme, zilawule. Lezi zifo ezimbili ziyizitha ezimbili eziyinhloko zokulimala kwezinso. Khuluma nodokotela wakho ngalokhu njalo.

Ngale ndlela yokuphila enempilo, ungagcina izinso zakho, lawa ma-capillary amancane kodwa abaluleke kakhulu e-peritubular ephilile, kanye nomzimba wakho wonke uphilile.
