Explanation:
The respiratory system supplies oxygen and removes carbon dioxide from the body, assisting cells in metabolism, acting in conjunction with the circulatory system, providing oxygen to body tissues. In addition, this system is related to smell, that is, our ability to allow odors and also related to speech, due to the presence of so-called vocal folds in one of the organs of the respiratory system.
This system is formed by the nose, nose cavity, pharynx, larynx, trachea, bronchi and lungs.
