What is "mouth"?

The mouth is an essential anatomical feature of the human body involved in various functions. It serves as the primary entrance for food and drink, allowing us to consume and ingest nutrients necessary for sustenance. The mouth houses several structures, including the lips, teeth, tongue, and palate. The teeth aid in chewing and breaking down food, while the tongue assists in manipulating the food and initiating the process of swallowing. Additionally, the mouth plays a crucial role in speech and communication, allowing us to articulate sounds and form words.
