प्रश्न
Describe how the exchange of oxygen and carbon dioxide gases takes place in the lungs.
उत्तर
At the time of respiration, the external air reaches up to the alveoli in the lungs. The oxygen in the air enters the blood vessels, which surround the alveoli. Through the network of blood vessels, oxygen is supplied to the entire body. At the same time, carbon dioxide is brought by the circulating blood into the alveoli. From here, carbon dioxide is given out of the body through exhalation. In this way, the exchange of oxygen and carbon dioxide gases takes place in the alveoli of the lungs.
