Questions: Functions of Saliva What are the functions of saliva? Drag and drop all that apply. Functions Lubrication of bolus Digestion of proteins Bactericide Digestion of starches Potential of hydrogen (pH) balance Digestion of nucleic acids Lubrication of mouth

The functions of saliva include:

1. Lubrication of bolus
2. Bactericide
3. Digestion of starches
4. Lubrication of mouth

Explanation:

• Lubrication of bolus: Saliva helps in moistening and lubricating the food bolus, making it easier to swallow.
• Bactericide: Saliva contains enzymes like lysozyme that have antibacterial properties, helping to control the bacterial population in the mouth.
• Digestion of starches: Saliva contains the enzyme amylase, which begins the digestion of starches into simpler sugars.
• Lubrication of mouth: Saliva keeps the mouth moist, which is essential for comfort, speech, and overall oral health.

The other options, such as digestion of proteins, potential of hydrogen (pH) balance, and digestion of nucleic acids, are not primary functions of saliva.
