What percentage of saliva volume does the submandibular gland produce?

1. 10-15%

2. 25-30%

3. 60-65%

4. 75-80%

The correct answer is: 60-65%

The submandibular gland is responsible for producing a significant portion of the saliva in the oral cavity, typically around 60-65% of total saliva volume. This gland plays a crucial role in the digestive process by secreting saliva that contains enzymes, which begin the breakdown of food. The amount produced by the submandibular gland is substantial as it is one of the three major salivary glands, alongside the parotid and sublingual glands. In comparison, the parotid gland, which is the largest salivary gland, contributes around 25% of total saliva, while the sublingual gland contributes only about 5% of saliva volume. Therefore, the knowledge of the contribution of the submandibular gland is essential for understanding salivary function and its importance in oral health and digestion. This anatomical knowledge is fundamental for dental professionals, as it assists in diagnosing and managing disorders related to saliva production and oral health.
