They can improve the sense of smell by increasing the area available to absorb airborne chemicals, and they can warm and moisten inhaled air, and extract heat and moisture from exhaled air to … However besides esthetics, the external nose also functions to protect the inner nose and allows the entry of air. For this mechanism to be … Nasal cavity. The nasal cavity is located just behind the two nostrils and forms the inside of the nose. What is Nasal Cavity protect the respiratory tract through the use of the mucociliary system. The olfactory region of the nasal cavity regulates the sense of smell. An anatomically correct finite element mesh of the right human nasal cavity was constructed from CAT scans of a healthy adult nose.
