The Respiratory System: Anatomy Review 1. Fill in the missing organs of the respiratory system: Nose (external nares) (air enters) nasal cavity Pharnyx (both air and food move through) trachea Primary Bronchus (large tubes leading to both lungs) lungs. 2. Each lung is surrounded by two layers of serous membrane known as pleurae. These are: Visceral pleura; covers the surface of the lung Parietal pleura; lines the thoracic wall The space in between is called the pleural cavity and it is filled with pleural fluid. This fluid assists breathing movements by acting as a lubricant. 3. Bronchial tree : Air flows from the trachea through the primary , secondary , and tertiary bronchi to smaller and smaller bronchi. The trachea and bronchi contain supporting cartilage to keep the airways open. Bronchi branch into branchioles , which do not contain cartilage but do contain more smooth muscle. This allows for regulation of airflow.
