What is the daily volume of saliva produced by the submandibular gland______________?
Show answer Hide answer
Answer: B. 450 ml
Explanation
The submandibular gland is a major salivary gland contributing a significant portion of resting saliva, producing about 450 ml daily. Mixed serous and mucous acini within this gland secrete a steady baseline volume of saliva into the oral cavity. Submandibular salivary output accounts for roughly seventy percent of total unstimulated whole saliva production. Major salivary glands include the parotid, submandibular, and sublingual glands located throughout the human head and neck. Normal human salivary glands collectively produce between one and one and a half liters of saliva daily. The submandibular duct, known as Wharton duct, opens into the oral cavity beneath the anterior tongue.
Option 750 ml overestimates the individual daily output typically contributed by the submandibular salivary gland. Option 1500 ml represents the total daily volume produced by all major salivary glands combined together. Option 1000 ml is an incorrect figure that does not reflect the measured output of the submandibular gland.
