Chiwindi ndi chiwalo chofunikira cha thupi chomwe chimayambitsa kuchotsa mphamvu, kuchepetsa thupi, kusakaniza, ndi kusungirako zinthu zosiyanasiyana. Chiwindi n'chofunika kwambiri pamoyo. Popanda izo, munthu sangathe kukhala maola oposa 24.
Kukula ndi Maonekedwe
Chiwindi ndi chiwalo chachikulu mkati mwa thupi (khungu limatengedwa kuti ndilo likulu lalikulu mu thupi lonse) ndipo limalemera makilogalamu pafupifupi 1500g.
Chiwalo ichi chofiira kwambiri chili pansi pa nthiti zomwe zili kumtunda kwa pamimba, pamunsi pa chithunzithunzi. Ambiri a chiwindi amatetezedwa ndi nthiti, koma n'zotheka kuti madokotala amve pamphepete mwake mwa kukankhira mwamphamvu m'mimba pamene wodwala akuwombera mpweya waukulu.
Pali ziphuphu ziwiri kunja kwa chiwindi, chowongolera chachikulu ndi chaching'ono chotsalira. Gulu la ziwalo zogwirizana zimagawaniza ndi kuteteza chiwindi mpaka pamimba.
Matenda a chiwindi amapangidwa ndi maselo ang'onoang'ono a maselo a chiwindi. Pakati pa maselowa, mitsinje yambiri imanyamula magazi ndi bile (madzimadzi opangidwa ndi kutuluka ndi chiwindi ndi kusungidwa mu ndulu ).
Zotsatira
Mavitamini, mankhwala, ndi zina (kuphatikizapo poizoni) amayenda kudzera mwazi kupita ku chiwindi. Pomwepo, zinthu izi zimasinthidwa, kusungidwa, kusinthidwa ndi kusokonezedwa. Iwo amatha kubwerera m'magazi kapena amatulutsidwa m'thumba.
Mothandizidwa ndi vitamini K, chiwindi chimapanganso mapuloteni omwe amathandiza pogwiritsa ntchito magazi. Chiwindi ndi chimodzi mwa ziwalo zomwe zimaphwanya maselo akale kapena owonongeka a magazi.
Metabolism
Chiwindi chimagwira ntchito yofunikira kwambiri mu mafuta, mafuta, ndi mapuloteni. Mafuta a metabolism, chiwindi chimathyola mafuta ndikupanga mphamvu.
Amapanganso madzi, a chikasu, a bulauni kapena a maolivi omwe amathandiza kuchepetsa ndi kutenga mafuta.
Mu shuga yamagazi, chiwindi chimathandiza kusunga mlingo wa shuga m'magazi anu nthawi zonse. Mukamadya, komanso shuga wanu umatuluka, chiwindi chimachotsa shuga m'magazi ndikuchiika mu mawonekedwe otchedwa glycogen. Ngati shuga wanu wa magazi ndi otsika kwambiri, chiwindi chimathyola glycogen ndipo chimatulutsa shuga m'magazi. Chiwindi chimasungiranso mavitamini ndi mchere (chitsulo ndi mkuwa) ndikuwamasula magazi.
M'thupi la mapuloteni, maselo a chiwindi amasintha amino acid mu zakudya kuti athe kugwiritsa ntchito mphamvu, kapangidwe kazakudya kapena mafuta. Njira imeneyi imapanga mankhwala ofooketsa otchedwa ammonia. Chiwindi chimatenga ammonia ndikuchiyambitsa mankhwala oopsa kwambiri omwe amatchedwa urea, omwe amamasulidwa m'magazi. Urea ndiye amapita ku impso ndikuchoka kunja kwa thupi mumkodzo.
