Chitsulo choponyedwavalavu yozungulira yozungulira

Chipata chotchinga ndi valavu yolowera mbali imodzi yomwe imayikidwa potulukira pa payipi yotulutsira madzi ndi ntchito zotulutsira madzi ndi ntchito zotsukira zinyalala.

Malinga ndi mawonekedwe ake, chitseko chozungulira ndi chitseko chotchinga chimapangidwa. Chitseko chotchinga chimapangidwa makamaka ndi thupi la valavu, chivundikiro cha valavu ndi gawo la hinge. Mphamvu yake yotsegulira ndi kutseka imachokera ku kuthamanga kwa madzi ndipo sifunikira kugwiritsa ntchito pamanja. Kuthamanga kwa madzi pachitseko chotchinga ndi kwakukulu kuposa komwe kuli kunja kwa chitseko chotchinga, ndipo chimatseguka. Kupanda kutero, chimatseka ndikufika pa kutuluka ndi kuyimitsa.
