Airways from the trachea to the terminal bronchioles are called the ______________ zone.Doesgas exchange occur in this zone? Gasexchange takes place in structures referred to as ______________, which are found in the ______________ zone.During exercise, bronchioles ______________, which increases airflow → allows more airto reach the respiratory zone with each breath. |
conducting no alveoli respiratory dilate |

Each lung is surrounded by two layers of connective tissue known as pleurae. These are ______________ pleura (covers the surface of the lung) and ______________ pleura (lines the thoracic wall).Thespace in between is called the ______________ cavity and it is filled with pleural ______________. This actsto keep the lungs in contact with the ______________ and also provides a ______________ forbreathing movements of the lungs. |
visceral parietal pleural fluid thoracic wall smooth surface |
