Yuav ua li cas yog lub qee thiab dab tsi yog nws tseem ceeb nyob rau hauv cov kev ua ntawm tus kab mob no

Tag nrho cov muaj sia nyob, inhabitants ntawm lub ntiaj teb, yog qhib lom systems. Kom muaj lawv lub neej xav tau kev pab lub inflow ntawm cov zaub mov, dej thiab cov pa los ntawm cov sab nraud ib puag ncig thiab cov kev tshem tawm ntawm metabolic khoom. Kom meej meej, xws li ib tug xaiv slag yog yuav tsum tau kom muaj homeostasis uas muaj sia nyob lub cev. Dab tsi ua rau qhov no vim tsis muaj hauv paus ntsiab lus? Tuag no tshwm sim vim lom ntawm lub hlwb tus kheej metabolites.

Evolution pab mus rau rov tshwm sim ntawm lub cev kev ua tau zoo muaj nuj nqi ntawm tshem toxins. Niaj hnub no, lawv muaj tag nrho cov neeg sawv cev ntawm cov tsiaj qus, xws li los ntawm cov nyuaj rau tib neeg. Nyob rau hauv no tsab xov xwm, peb yuav nrhiav tau tawm yog dab tsi ib tug xaiv, thiab mus tshawb nws cov nta, cov yam ntxwv ntawm lub loj pawg ntawm cov kab mob no.

lus qhia dav dav

Kab mob uas muaj ib tug tib cell, muaj ib tug zoo meej zog ntawm nws tus kheej-kev cai thiab detoxification, tsim raws li ib tug tshwm sim ntawm dissimilation. Piv txwv li, Amoeba Proteus thiab ntsuab euglena tshem tawm toxins thiab tshaj dej los ntawm lub cell daim nyias nyias thiab contractile vacuole. Nws qhia txog hais tias ib tug xaiv ntawm metabolites yog yooj yim adaptation rau lub cev qauv thiab dej vaj tse. Multicellular kab mob complicate tus txheej txheem ntawm tshem toxins. Nyob rau hauv tiaj, round, annelids thiab mollusks tshwm hlab - protons los yog metanephridia.

Rau cov qog nqaij hlav yus muaj los ntawm ntsuab caj pas, thiab kab tsim Malpighian hlab ntsha thiab muaj roj lub cev. Cov tsos ntawm lub chord thiab lub internal cev pob txha radically hloov qee txheej txheem. Biology ntawm vertebrates qhia lub tsim ntawm complex kabmob - raum paired. Xav txog lawv cov qauv thiab ua rau.

Evolution ntawm lub excretory system

Ntses muaj ib tug xov zoo li mesonephros, dag rau hauv tog ntawm tus txha nqaj thiab filtering ntshav. Amphibians compact excretory kabmob nyob rau hauv lub sacral vertebra. Ntawm no, cov ureter zis kis mus rau hauv lub cloaca. Cov tsos ntawm cov pelvic raum nyob rau hauv cov tsiaj reptiles, noog, tsiaj thiab tib neeg - yog ib tug tseem ceeb aromorphosis.

Raum nephrons ua ob txoj physico-tshuaj txheej txheem: filtering ntshav thiab reabsorption thawj zis. Raws li ib tug tshwm sim, cov ntshav yog kiag li ntxuav ntawm toxins, uas muab ib tug physiologically ib txwm muaj ntawm homeostasis.

Nyob rau hauv xaus

Nyob rau hauv no tsab xov xwm, peb ntsia li ib tug xaiv. Tam sim no koj paub tus yam ntxwv ntawm txoj kev no nyob rau hauv sib txawv pab pawg ntawm cov kab mob.
