Respiratory system It is the one that is in charge of taking the oxygen that is in the environment and releasing the CO2 that has been created inside us Parts of the respiratory system Nostrils: both cavities have the same shape and are separated by a partition of bone and cartilage. They are located above the oral cavity and are the area of reception and exit of air. Pharynx: it is a muscular tube of around 14 cm in length that communicates from the bottom up with the middle ear, the mouth, the larynx and the esophagus, and which directs the air towards the trachea by muscular contraction. Larynx: it is located in the middle area of the neck, in front of the pharynx, following the trachea below it. It is about 4 cm long and is the organ in charge of phonation. Trachea: as we have pointed out, it follows the larynx and is located in front of the esophagus. It is made up of a series of vertical cartilaginous rings in the form of a "c", covered by tissue. In the incomplete zone there is a muscle in charge of allowing food to pass through without problems.
