Advantages and disadvantages of complex 3D in vitro culture models of the human lung for inhalation exposure studies. Each model presented has unique benefits and challenges. Improved airway modeling can be achieved through incorporating inhalation exposure systems. The digital images of human lung at the center and bronchus near the bottom left were acquired from Shutterstock and Biorender, respectively.
