How Do Nanoparticles Enter the Body Through Inhalation?
Nanoparticles can be inhaled through various routes such as air pollution, occupational exposure, or nanomedicine treatments. Once inhaled, nanoparticles traverse through the nasal passages, pharynx, and trachea, eventually reaching the bronchi and alveoli. The small size of these particles allows them to bypass many of the body's natural defense mechanisms.
