Nasal passage inferior

The nasal passages of the lower sections are part of the respiratory and olfactory systems, which are located in the nasopharynx. In turn, the nasal passages are divided into 3 parts: superolateral, posterior and ophthalmic. The nasal cavity, or nose, is the opening between the mouth and nostrils. It is a cavity in the facial part of the skull, communicating with the upper respiratory tract through the choanae - the openings of the skull. The nasal cavity is divided into two longitudinally by the septum and three transversely by slopes; in each of these parts it is located along the side wall of the nasal cavity.
