The respiratory system is responsible for the exchange of oxygen and carbon dioxide between the body and the environment. It includes the lungs and airways such as the trachea and bronchi.
Oxygen is inhaled into the lungs, where it diffuses into the bloodstream and binds to red blood cells ftor distribution to cells throughout the body.
Carbon dioxide, a waste product of metabolism, is transported back to the lungs and exhaled. This exchange ensures the body’s cells receive oxygen for energy production and expels carbon dioxide to maintain proper pH levels. The respiratory system supports oxygenation and removal of waste gases, vital for overall functioning.
