The term "inferior nasal" typically refers to the inferior nasal concha, a small, curved bone located within the nasal cavity. This bone is one of the three pairs of nasal conchae, which also include the superior and middle nasal conchae. The inferior nasal concha plays a crucial role in filtering, humidifying, and warming the air we breathe before it reaches the lungs. The inferior nasal concha is situated below the middle nasal concha and is the largest of the three. It is composed of spongy bone and is covered by a mucous membrane. This structure helps to increase the surface area of the nasal cavity, enhancing its ability to trap particles and pathogens, thus contributing to overall respiratory health.
