Forming the main external opening of the respiratory system, the nose protectsthe anterior portion of the nasal cavity. The nose is also unique, as it is the only part of the system that is externally visible. The nasal cavity is the uppermost part of the respiratory system, divided into two by the nasal septum. It is the best entrance for outside ...
The paranasal (meaning around the nose) sinuses are four paired, hollow spaces above and below the eyes. Connected to the nose by small openings, they regulate the temperature and humidityof inhaled air. These cavities also give tone to the voice. Sinuses develop after birth and reach their final size around the age of 20.
The pharynx, or throat, is a versatile muscular tube, shaped like a funnel, that delivers air from the mouth and nose to the trachea, or windpipe. It also connects the nasal and oral cavities with the larynx and esophagus. The pharynx is key to the respiratory and digestive systems. It allows inhaled air to pass from the nasal cavity to the larynx,...
The larynx has a dual functionin the respiratory system: as an air canal to the lungs (while stopping food and drink from blocking the airway) and as the “voice box” (which contains vocal cords for speech). The larynx is a 2-inch tube made up of nine cartilage pieces. It connects the pharynx with the trachea and is held together by ligaments, membr...
The lungs are the primary organs of the respiratory system, as they perform a vital role in breathing: gas exchange. The air that a person breathes in through the nose and mouth contains oxygen and other gases. Oxygen enters the lungs, then the bloodstream, allowing the body to function normally. However, the lungs also take the carbon dioxide from...
The trachea runs down the neck and upper chest. It is a wide, hollow tube that connects the larynx to the bronchi, or airways, of the lungs. Its most vital function is to enable airflow to and from the lungs. The fibroelastic membrane expands and contracts during inhalation and exhalation.
The diaphragm is a dome-shaped sheet of muscle located below the lungs. It separates the chest from the abdomen. The diaphragm operates as the major muscle of respiration and aids breathingTrusted Source. The parasympathetic nervous system regulates the contraction and relaxation of the diaphragm and intercostal muscles.

Oct 30, 2023 · The respiratory system works as a whole to extract the oxygen from the inhaled air and eliminate the carbon dioxide from the body by exhalation. The upper respiratory mainly has an air-conducting function, while the lower respiratory tract serves both the conducting and respiratory functions.
