The respiratory system is a very important organ system in the human body. Its purpose is to transport oxygen to the blood where it can then move through the bloodstream to oxygenate all parts of the human body. The organs in the respiratory system consist of the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs. Each organ plays an important role in respiration. The nasal cavity is the organ through which oxygen enters the body. This is the most superiorly and superficially located of the respiratory organs. Located posterior to the nose, the nasal cavity is a hollow space inside the skull that is lined with hairs and mucus membranes that help filter environmental contaminates, such as pollen and dust, out of the air before it moves to the next organ, the pharynx. The pharynx is located inferiorly to the nasal cavity. The pharynx is a muscular, tube shaped organ that allows air to travel through both the nasal cavity and the mouth into the superior portion of the larynx. As the air makes its way to the next organ it must pass through the epiglottis, which is a cartilage flap that protects from accidental inhalation of food and liquids. The next organ is the larynx which is located inferiorly to the pharynx. This is a short tube-shaped organ that is primarily constructed of cartilage. The larynx houses the vocal folds which are mucus membranes that vibrate at variable speeds while air is passing through to produce vocal sounds.
