Description: The term ‘nasal’ refers to everything related to the nose, a vital organ in the human respiratory system. The nose not only serves essential functions in breathing but also plays a crucial role in the sense of smell. Anatomically, the nose is composed of bony and cartilaginous structures that form the bridge and nostrils, as well as mucous membranes lining its interior. These membranes are responsible for filtering, warming, and humidifying the air we inhale, thus protecting the lower respiratory tract from harmful particles and microorganisms. Additionally, the nose contains olfactory receptors that allow for the perception of odors, which is fundamental for feeding and detecting dangers. The shape and size of the nose can vary significantly among individuals and populations, which can also influence voice resonance and facial aesthetics. In terms of health, nasal conditions such as rhinitis or sinusitis can affect quality of life, highlighting the importance of this organ in overall human well-being.
