Activitatea secretorie a cavitatii bucale se datoreaza glandelor salivare. Zilnic se screta 800-1500 ml de salica care contine 99.5% apa si 0.5 %reziduu uscat. Principalii electroliti di saliva sunt: NA+, Cl-, HPO3(2-), Mg2+ si

That's Correct!
It's Wrong!
The correct answer is Ca2+. The explanation for this is that the question is asking about the main electrolytes in saliva, and Ca2+ is one of them. Saliva is secreted by the salivary glands and contains various electrolytes, including sodium (Na+), chloride (Cl-), phosphate (HPO3(2-)), magnesium (Mg2+), and calcium (Ca2+). Therefore, Ca2+ is the correct answer.
