Answer 1

Mammals are unique in possessing a diaphragm to pull O2 into the lungs. The voice box is the larynx. Both the digestive and respiratory tracts are shared by the pharynx. Pseudostratified ciliated columnar is the epithelial tissue that is destroyed by smoking but can regenerate if smoking stops. The role of surfactant is to reduce surface tension. The primary role of hemoglobin is to carry oxygen. The inflammation of bronchi is called bronchitis.
