The ________ duct empties into the vestibule at the level of the second upper molar.
gavmur [86]

The parotid duct empties into the vestibule at the level of the second upper molar.

Around the back of your lower jaw is where the parotid gland is located. Saliva then passes via a tube known as the parotid duct. The duct's opening is where the saliva spills into your mouth. Different factors might cause the parotid duct to become clogged. The region may swell up as a result of this.

Each gland's front faces a lengthy excretory channel called the parotid duct, which emerges just beneath the masseter muscle. The duct enters the mouth by the buccinator muscle and opens on the inner cheek surface, typically next to the maxillary second tooth
