    What is the primary function of saliva?

    The process of breaking down carbohydrates in the mouth.

    Which salivary gland produces the majority of saliva?

    The submandibular gland produces the largest volume of saliva compared to other salivary glands.

    What is the estimated daily saliva production in a healthy adult?

    A healthy adult produces roughly 1-1.5 litres of saliva daily.

    What term describes the consistency of saliva produced by submandibular glands?

    Saliva produced by the submandibular glands has both serous (watery) and mucous (thick) components.

    Study Notes

    Saliva

    • Saliva is a colorless, slightly sticky solution produced by salivary glands.
    • Saliva can be serous or mucous in consistency.
    • Humans produce between 1-1.5 liters of saliva daily.

    Sources of Saliva

    • The three major salivary glands produce varying amounts of saliva.
      • Submandibular gland: 60-65% of total volume
      • Parotid gland: 25% of total volume
      • Sublingual gland: 5-10% of total volume
    • Minor salivary glands also contribute to saliva production.

    Saliva Properties

    • Saliva is a colourless, slightly sticky solution produced by the salivary glands.
    • Saliva can be either serous or mucous in consistency.
    • The average person produces between 1-1.5 litres of saliva every 24 hours.

    Sources of Saliva

    • Each major salivary gland, along with the minor glands, produces varying amounts of saliva.
    • The submandibular gland produces 60-65% of total saliva volume.
    • The parotid gland produces 25% of total saliva volume.
    • The sublingual gland produces 5-10% of total saliva volume.
    • Minor salivary glands also contribute to saliva production.
