Экскреция протонов и аммиака

Почки и лёгкие играют основную роль в поддержании pH (гомеостаза) межклеточной жидкости в организме (см. Кислотно-основной баланс), причём почки вносят вклад в регуляцию кислотноосновного равновесия, осуществляя активную экскрецию ...

 
А. Секреция протонов

Клетки дистального отдела нефрона (извитого канальца и собирательных почечных трубочек) переносят протоны (Н+) из крови в просвет канальца (в мочу). Секреция идёт против градиента концентрации, поскольку ...

Б. Экскреция аммиака

Аммиак оказывает на клетки сильное токсическое действие. Основным путём обезвреживания аммиака в печени является образование мочевины (цикл мочевины, см. Эйкозаноиды). Главным источником аммиака в почках служит глутамин ...
