Question

is mouth and buccal cavity the same? or there's some difference...​

Answer 1

The mouth is also called as the buccal cavity or the oral cavity. In the human digestive system mouth is the upper end or the beginning of the alimentary canal, which leads to the pharynx and to the esophagus. In humans, both the mouth or the buccal cavity and the nasal cavity are separated by the palate.
