Answer 1

Answer:

Many environmental and occupational agents as well as some pharmaceuticals enter the respiratory tract through inhalation. Absorption can occur at any place within the upper respiratory tract. However, the amount of a particular xenobiotic that can be absorbed at a specific location depends highly on its physical form and solubility.

There are three basic regions to the respiratory tract:

Nasopharyngeal region

Tracheobronchial region

Pulmonary region
