<unk> , or Nose<unk>  is the<unk>  in the nose. Adult humans have<unk> s in the anterior<unk>  passage. These<unk> s act as a fibrous filter for inhaled particles. Diffusion of ultra fine particles to the<unk>  occurs mostly for particles < 5 nm.<unk>  has important implications for the health of the human body because a lack of<unk>  could invite the transport of potentially harmful particles into the respiratory system.<unk>  should not be confused with cilia of the<unk>  cavity, which are the microscopic cellular strands that, unlike macroscopic<unk> , draw mucus up toward the oropharynx via their coordinated, back-and-forth beating.
