Which term describes the function of saliva for clearing food?

• A. Salivary Flow
• B. Fats (Lipids)
• C. Proteins
• D. Fluoride

Answer: (A)

Saliva clears food mainly through its production and movement—the salivary flow. When you eat, glands continuously release saliva that bathe the mouth, washing away small food particles, diluting sugars, and helping to rinse debris from teeth and gums. This cleansing action comes from how much saliva is produced and how it flows, not from the other substances listed. Fats (lipids) are nutrients, proteins are structural or enzymatic components, and fluoride is a mineral used to strengthen enamel—none describe the mouth-cleaning function of saliva. So, salivary flow best describes the clearing of food by saliva.
