The excretory maitiro wemunhu: pfupi uye zvinozipa

Uwandu chikafu kuti tinodya muupenyu hwangu, makumi ezviuru matani, uwandu kudyiwa zvinwiwa - kukosha chete kurongeka. Kusvikira zvino, hapana dzinoputika, kunyange nyaya kucharamba wosekwa. Chokwadi chokuti zvose anwa inopfuura polycycle chokuita azvikuya uye nemakemikari kushanduka. Uye zvinotora marara kwevanhu excretory hurongwa. The mharidzo nezvenyaya iyi vachava vashoma. Unofanira 4 mapeji: pamusoro itsvo, mapapu, muura chiropa, ganda.

Itsvo - vashandi kupfuura muviri ari oga: 70% zvachose tsvina goho navo. Vanoshanda pamwechete zvikuru zvine chepfu, inova muviri chakaipa - zvivezwa mapuroteni muviri: creatinine, urea uye uric acid. Ivo dzinoitawo murau pamusoro zvinwiwa, munyu, uye kubatsira kubvisa dzimwe zvinhu. Itsvo ngozi pokuvanda kumativi ose; mamiriro anodzivirira nhengo idzi excretory ezvinhu murume. Kana mumwe netsvo vanorwara, wechipiri anotora pamusoro basa.

itsvo chigadzirwa - weti - unoitwa kubva ropa, kunyange zvazvo asina chakanaka mukurumbira yokupedzisira. Paaiva kuIndia, kusvikira Urume iri kuremekedzwa. The weti hapana chii asingadi kuva ropa. Itsvo yatorwa ropa zvose zvisina basa, uye kusiya muviri muviri. The ropa itsvo anomhanya 2 kutendeuka rwakazara. Chekutanga zvinotoda chaizvo, kunyange kubatsira, ipapo vakanwa zvakanaka shure. Nokuti kutanga muitiro inofanira kuva pasi pamusoro simba, wechipiri ane chaizvo mari saka shoma itsvo anodya 10% of okisijeni kuti akaenda muviri. Zvikuru yevanhu excretory hurongwa inoda oxygen.

The zvakawanda weti goho, ari mukobvu inova midziyo ropa, uye vakutarisire. Uye huwandu mvura muropa midziyo kwokudzvinyirira kunoenderana zvakananga. Kana kumanikidzwa anodonhedza - kunyange mupise hazvizoitiki, uye kana kumanikidza kukuru, kuti nephrons (fukntsionalnye zviumbu) achaita massively kupera. Kuzvidzivirira, itsvo kubereka renin. kemikari Izvi zvinobvumira kuti kuchinja kufurirwa. Sezvo itsvo dzinonetsa vanoda okisijeni, ivo zvibereko erythropoietin, iyo hunokonzera mumwongo kuumba matsvuku masero - okisijeni vatakuri. Saka nguva dzose iwe hauna mhepo zvakakwana panguva run, imi munoziva kuti Itsvo panguva ino, chiratidzo pamusoro masero matsvuku eropa.

Weti kusvika dundira, apo iri zvakachengetwa kusvikira nguva apo munhu mukuru anosarudza zviri izvozvo. Mukomana mwana rikurumidze kuti Rinotarisira musana, asi mumakore maviri ripen nzvimbo yakakodzera uropi uye mwana anodzidza potty. Zvisinei, kunyange mukuru anogona kurasikirwa kudzora weti rikurumidze kana weti iri dundira anopfuura 500 Rine mamiririta. Hahugoni akashivirira kwenguva refu nguva dzose: kurega kunotanga kuti weti uye paumbwe namabwe.

Kana netsvo pavanokundikana, matambudziko akawanda anogona kugadzirisa ganda. Zviri runopwa kumirangariro ity pazuva. Kana netsvo vanorwara, ziya anogona dzakafafadzwa weti. Also emit chiedza nechokunze fuma - kusanganisira 400 ml mvura.

Human excretory hurongwa inosanganisira mugaranhoko. Rinobatanidzwa ne chiropa, nekuti vazhinji chepfu fecal nyaya akawana kubva bile, uye bile kubva chiropa zvinowanisa munhu "abatwa" zvinhu kubva ropa. Zvisinei, kuti vabudise mutsvina yadzo nyore - kushanda abdominal tsandanyama uye ura panguva imwe chete. The mugaranhoko iri vachidurura chaiye kanomwe pazuva, paavhareji, mumwe wedu famba 150g. Itsvo romwedzi unoratidzwa inenge 45 litres kuti weti. Saka kuti mutoro pamiviri izvi yakawanda.

Human excretory hurongwa inoshanda zvakanaka, kana paine matambudziko imwe nhengo, vamwe vari kutora womumwe basa. Kana chiropa anorwara kana itsvo basa, mapuroteni metabolic zvinogadzirwa goho mapapu uye ganda, uye kana chiropa havagoni kukurira Chizenga muviri tsvina, ipapo zvichava riitwe neitsvo.
