Respiratory System meaning

The respiratory system is responsible for the exchange of gases between the body and the environment, supplying oxygen to the bloodstream and removing carbon dioxide. It includes the nose, pharynx, larynx, trachea, bronchi, and lungs. The primary function of the respiratory system is to facilitate breathing, which involves inhaling oxygen-rich air and exhaling carbon dioxide-laden air. The lungs play a central role in gas exchange, with alveoli serving as the sites where oxygen and carbon dioxide are exchanged between the air and blood. Proper functioning of the respiratory system is essential for maintaining cellular metabolism and overall health.
