Final answer:
The inferior nasal concha is the largest and is situated below the other conchae, with the space beneath it being called the inferior meatus.
Step-by-step explanation:
Inferior to each pair of nasal conchae is its nasal meatus. The nasal cavity features three conchae on each side: the superior, middle, and inferior nasal conchae. These conchae are bony projections that increase the surface area within the nasal cavity, aiding in warming, moisturizing, and filtering the air as it is inhaled. The largest and most inferior is the inferior nasal concha. It is an independent bone that projects from the lateral wall of the nasal cavity. Below each inferior concha is an air passageway called the inferior meatus. The superior and middle nasal conchae are part of the ethmoid bone. The conchae and adjacent meatuses play a crucial role in the function of the respiratory system by swirling the incoming air and trapping moisture and debris.
