Final answer:
The Vienna Nasal Speculum is a device for retracting nasal walls to view structures such as the nasal septum and nasal conchae, each with specific functions in air filtering and humidification.
Step-by-step explanation:
The Vienna Nasal Speculum is a medical tool used for retracting the nasal walls during examinations and procedures. The nasal cavity is split into left and right parts by the nasal septum, and each lateral wall features the superior, middle, and inferior nasal conchae. These conchae are curved bony structures that extend into the nasal cavity, aiding in the warming and moisturization of incoming air and trapping particles like dust and bacteria through mucus secretions. The superior and middle conchae arise from the ethmoid bone, while the inferior concha is an independent bone.
The space below each concha is referred to as a meatus, which increases the surface area within the nasal cavity, enhancing the air purification process.
