Answer:
Sublingual glands secrete saliva via lesser sublingual ducts and are located under the tongue, while submandibular glands, located under the jaw, also produce saliva helping in digestion.
Step-by-step explanation:
The sublingual glands are salivary glands located beneath the tongue. These glands secrete saliva through the lesser sublingual ducts directly into the oral cavity, which is essential for beginning the process of digestion and maintaining oral health. Saliva produced by the sublingual glands acts as a lubricant and contains enzymes that initiate the breakdown of food. Similarly, the submandibular glands, positioned under the lower jaw, contribute to saliva production through the submandibular ducts.
