Respiratory System Summary The air retrieved then travels to the pharynx which is a structure between the nasal cavity and larynx, this is where the tonsils are, the role of the tonsils in this instance is to protect from any foreign antigens that may have been inhaled. This is possible as the tonsils contain lymphocytes and it is helping towards maintaining homeostasis as a result. The air retrieved then travels to the pharynx which is a structure between the nasal cavity and larynx, this is where the tonsils are, the role of the tonsils in this instance is to protect from any foreign antigens that may have been inhaled. This is possible as the tonsils contain lymphocytes and it is helping towards maintaining homeostasis as a result, by not allowing homeostasis to be disrupted. There is an air passage within the pharynx which lies next to the food passage and both open in the laryngopharynx which is a section of the pharynx. Then the air travels through the glottis which opens up to the larynx which acts as the passageway to the trachea that is part of the lower respiratory tract, the larynx consists of cartilage walls so it is firm yet flexible. This is where the voice box is located and when air is pushed through the glottis, it causes the vocal cords to vibrate which produce sound, so different aspects of the respiratory system have a different purpose. Each of the organs in the respiratory tract assists with air travelling through a passage, connecting to subsequent organs, ultimately the lungs. The trachea is the tube which connects the larynx to the primary bronchi. The walls consist of connective tissue which is supported by cartilaginous rings, which protect and maintain the airway. Within the lining of the trachea there is a mucous membrane containing goblet cells which produce mucus that can trap debris as it passes, which is then removed
