1. Anatomically food intake and air intake pathways are structurally shared. Describe the embryological events that lead to the development of the trachea and the relationship of these events, and pertinent tissues, to the gut tube.
2. Anatomically, there are two pleura layers associated with the lungs within the thoracic cavity. Describe the relationship of the pleura layers to the lower respiratory systems. What key developmental events lead to this relationship? Include in your answer the origins of the following anatomical structures: visceral and parietal pleura, hilum and root of the lung, pulmonary ligaments, septum transversum and diaphragm and the importance of space (pericardioperitoneal canals).
