Ndepipi itsvo dziri vanhu uye zvazvinoreva mumuviri

Mune munhu, nhengo dzose dzakabatana zvakanyanya, dzichiumba pamwe chete imwe nzira, nekuda kwekuti kushanda kwenyama yose kunovimbiswa senzira imwe chete. Munhu wose anoziva nezvebasa rinokosha remwoyo uye chiropa, mudumbu uye mumatumbo, mapapu uye pancreas. Zvisinei, hapana basa risina kukosha rinowedzerwa nehutano hukuru hwemuviri wedu, nhengo dzinokosha dzayo dziri itsvo.

Zvechokwadi munhu wose anoziva kwaanoita itsvo dziri mukati mevanhu, asi havasi vose vanonzwisisa kukosha kwavo. Tsvete ndiyo nhengo huru ye genitourinary system, iyo inenge inenge 1 500 malita eropa inoyerera zuva rega rega. Kuvonga kwezvikamu izvi zvinokosha zvemukati, ropa rinochenesa kubva kune zvinokuvadza zvinokonzera izvo zvinopinda nemugini. Mukuwedzera , itsvo dzinobatsira kuchengetedza kuenzanisa kwe-acid-base mumuviri, pamwe nekugadzirisa mvura-electrolyte muyero, kuwedzera kukonzerwa kweropa nekuda kwekuchinja kwezvakatipoteredza nemamiriro ekunze.

Apo itsvo dziripo mumunhu, mwana wechikoro umwe neumwe akapfuura maitiro anokwanisa kuratidza. Icho chiri muchikamu chepasi chemuviri, pedyo nechekomba yenharaunda, kune rumwe rutivi rwemutsara wemupfupa. Inso imwe neimwe inhengo yechipfuva ine chimiro chebhandi, iyo yakareba yakaita seyakagadzirwa nemasendimita gumi nemaviri, uye upamhi hwakaita sendimita yemasikati matanhatu. Pasinei nekuti mazai acho akaoma kwazvo, nokuti akafukidzwa nehuwandu hwevascular tubules (nephrons), ivo vakajeka uye vanorema pamwe chete, Kupfuura mwoyo. Mune imwe neimwe yeitsvo kune mamiriyoni 1 nephrons anoshandura muMalpighian tangle, akadonhedzwa mu Bowman-Shumlyansky capsule yakagadzirwa. Iyi tangle yemapapillari yakavharwa mune dense renal corpuscle, iyo inopinda mucheka mutsvuku unobatanidzwa kune renal pelvis, uko inotanga kubuda. Nokudaro, nzvimbo dzinosangana neitsvo mumunhu dzinodzivirirwa kubva kumusoro nenyundo, uye mberi nekumashure nemisungo yakanyanyisa yemudumbu, iyo inochengetedza chimiro ichi kubva kune dzimwe nyika.

Vana vanoda kuziva kuti itsvo dziripi kuvanhu, sezvo izvi zvingaita basa rinokosha pakutsanangura zvirwere zvakasiyana-siyana mumatangiro ekutanga. Zvinosuruvarisa, nhasi kune vanhu vanenge mamiriyoni 500 munyika iyo vanotambura neutsvo kusakundikana. Munyika yedu, chiratidzo ichi chinokurawo pamwero mukuru, izvo zvinoratidza kutyisa kwehuwandu hwezvirwere zvepfungwa muhutano hwematambudziko enyika. Dambudziko guru nderokuumbwa kwemakumbo emangwana , ayo mune ramangwana angada kunyange kushandiswa kwekuvhiya. Kwenguva yakareba yakatendwa kuti kunaka kwemvura uye kusagadzikana kwacho kwakaita basa rinoita mukugadzirwa kwemafuta emhino, asi zvidzidzo zvenguva ino mumunda izvi zvakaratidza kuti maitiro ekugadzirisa kwevanhu munhu anotungamirira kunotungamirira mukuvhiringidza kushanda kweiyo itsvo. Kuonga kuvhiyiwa kwemazuva ano, zvinokwanisika kuita mabasa ekurapa kwepfungwa yematombo. Izvo zvose zvinotarisana uye nzira isina kufanira yekutsvaga, zvose zviri kubudirira kushandiswa kurapa chirwere ichi.

Nokudaro, nzvimbo iyo iyo itsvo dziri mukati mevanhu, saiyo itsvo pachavo, inowanzoshungurudzika, sezvo inotora kusvibiswa kwose neukisi. Ndicho chikonzero nei kunyanya kunzwisiswa panyaya iyi kunofanira kupiwa kune zvakakosha kudya, sezvo kune rumwe rutivi rwekudyidzana kwezvakatipoteredza uye utano hwakanaka hunobatanidzwa zvakanaka nemuviri wedu, uye kune rumwe rutivi vanochenesa miviri yedu yeupisi uye chepfu. Uye kushambadza periodic yeiyo itsvo kunokosha kune umwe neumwe wedu.

Munzvimbo idzodzo apo itsvo dziri mukati mevanhu, pane dzimwe nhengo dzinokosha dzinobatsirawo kuchenesa ropa. Ndokusaka iwe uchifanira kuchengetedza muviri wako.
