The trachea is shaped like a pipe. When a person breathes in, the trachea filters the air down into the bronchi, two air tubes that then carry air directly to the lungs. The main organs of the respiratory system are the lungs. They take oxygen into the body and breathe out carbon dioxide. Oxygen is retrieved from the lungs by red blood cells that then carry the oxygen throughout the body to the cells that need it.
The Respiratory System is vital to every human being. Without it, we would cease to live outside of the womb. Let us begin by taking a look at the structure of the respiratory system and how vital it is to life. During inhalation or exhalation air is pulled towards or away from the lungs, by several cavities, tubes, and openings. The organs of the respiratory system make sure that oxygen enters our bodies and carbon dioxide leaves our bodies. The respiratory tract is the path of air from the nose to the lungs. It is divided into two sections: Upper Respiratory Tract and the Lower Respiratory Tract. Included in the upper respiratory tract are the Nostrils, Nasal Cavities, Pharynx, Epiglottis, and the Larynx.
