Organic material ,inorganic material and 95% water and then in organic componen has the highext consentration is natriun and kalium and than the main organic material is protein and mucin also found are lipid glucose ,aminoac ,urea and vitamin Saliva also contain ptyalin enzim ( amylase salivaris ) Saliva also contain tirosin ( milon test ) Anti bacterial compound example thiocianat ,hydrogen peroksida ang imonoglobulin A The function of amylase salivaris to change glycogen in to smaller polisakarid Saliva also anorganic componen exemple : natrium,kalsium,kalium,magnesium,klorida  bikarbonat and fosfat

3. What is the mecanism of saliva secrtion ? ( 3 ) 









Kemoresptor –  respons of food pressure –  the impuls start at fiber aferen nerv - information to the center of saliva at medulla ( batang otak ) - at the center of saliva send implus otonom extrinsif otonom nerve –  secretion of saliva increase Parasimpatis stimulation → have a dominan role –  produc liquit saliva large quantities and countain a lot of enzim Simpatis stimulation ( stress ) –  smaller volume viscouse saliva ( mucous ) –  decrease secretion saliva The speed of saliva secretion is different.the secretion of saliva is reach minimum if there any stimulation and maximum when there is not stimulation.average of saliva fluid is 20 ml/hour while rest ,150 ml/hour while eating ( 0,6 ml/menit ) and 20-50 ml/hour while sleep When chew some food the secretion of parotit gland will increase.
