Final answer:
Clara cells are the predominant cell type in the terminal bronchioles, serving detoxification, secretion of surfactant components, and protection of the bronchioles.
Step-by-step explanation:
The cell that is found in large numbers in the terminal bronchioles is known as the Clara cell. The Clara cell, also termed as Club cell, is a non-ciliated, dome-shaped cell that detoxifies harmful substances inhaled into the lungs. These cells are also responsible for secreting components of the surfactant that lines the respiratory tract assisting in the maintenance of the airway lining fluid balance and serve a protective role in the lining of the bronchioles.
