1функция почек – выделительная, то есть очистка организма от шлаков и токсинов, при этом почки отвечают за полную сохранность полезных веществ. Почки принимают участие в фосфорно-кальциевом обмене и формировании костной ткани

2 Мочеточники парный мочевыводящий орган, который служит для отведения мочи в мочевой пузырь. После наполнения пузыря просвет мочеточников автоматически перекрывается, предотвращая возврат мочи в почка

3 Мочевой пузырь выполняет функцию резервуара мочи, из которого она выводится наружу; иными словами, он служит для накопления оттекающей из почек мочи и периодического её выведения через мочеиспускательный канал, регулируемого с детрузора.
