Kodi Kugawilidwa kwanthaka ndi chiyani tanthauzo lake ndi ntchito ya zamoyo

zamoyo zonse, okhala padziko lapansi, ndi lotseguka machitidwe kwachilengedwenso. Kukhalabe moyo wawo amafunika inflow chakudya, madzi ndi mpweya ku malo akunja ndi kuchotsa mankhwala kagayidwe kachakudya. Motero, kusankha slag chofunika kukhalabe homeostasis wa thupi. Kodi chimayambitsa kupanda mfundo? Imfa kumachitika chifukwa poyizoni wa maselo yekha metabolites.

Evolution chinathandiza zikamera wa matupi kugwira ntchito yochotsa poizoni. Lero, iwo ndi nthumwi zonse zinyama, kuyambira losavuta anthu. M'nkhaniyi, ife tipeza zomwe kusankha, ndi kufufuza zinthu zake, khalidwe la magulu akuluakulu a zamoyo.

zambiri

Zamoyo wopangidwa mwa selo imodzi, ndi dongosolo langwiro wodzilamulira lamulo ndi detoxification, anapanga chifukwa cha dissimilation. Mwachitsanzo, Amoeba Proteus ndi wobiriwira euglena kuchotsedwa zoipa ndi madzi osafunikira mwa selo nembanemba ndi contractile vacuole. Iwo n'chakuti kuti wosankhidwa wa metabolites ndi anatengera losavuta kapangidwe thupi ndi m'madzi malo. zamoyo Multicellular kusokoneza ndondomeko kuchotsa poizoni. Mu mosabisa, kuzungulira, annelids ndi mollusks limapezeka machubu - mapulotoni kapena metanephridia.

Pakuti khansa yodziwika ndi England wobiriwira, ndi tizilombo akupanga zipangizo Malpighian ndi thupi mafuta. Maonekedwe a poyambira ndi mafupa mkati ukasintha amasintha ndondomeko Kugawilidwa kwanthaka. Biology of inakhala limasonyeza mapangidwe ziwalo zovuta - impso wophatikizidwa. Taonani dongosolo zawo ndi kugwirira ntchito pa.

Evolution a dongosolo excretory

Nsomba ndi riboni ngati mesonephros, kunama mbali ya magazi msana ndi sefa. Achule yaying'ono ziwalo excretory ili mu linkawonongeka sacral. Wa awa, ureter mkodzo akudutsa mu cloaca lapansi. Maonekedwe a impso m'chiuno mwa zokwawa, mbalame, nyama ndi anthu - ndi aromorphosis zofunika.

nephrons aimpso anachita zovuta awiri ndondomeko physico-mankhwala: imathandiza magazi ndi reabsorption mkodzo chachikulu. Chifukwa, magazi kwathunthu kutsukidwa wa poizoni, amene amathandiza mlingo physiologically wabwinobwino wa homeostasis.

pomaliza

M'nkhaniyi, ife anayang'ana pa zimene kusankha. Tsopano inu mukudziwa makhalidwe a ndondomeko izi mu magulu osiyana a zamoyo.
