During the exchange of airing, your lungs oxygen is being taken into your bloodstream all the substances being released

Answer 1

from your cells, such as carbon dioxide. This process is known as gas exchange or pulmonary gas exchange.

When you inhale, air enters your lungs through the bronchi, which then branch into smaller tubes called bronchioles. At the end of the bronchioles, there are tiny air sacs called alveoli. The alveoli are surrounded by a network of tiny blood vessels called capillaries.

During gas exchange, oxygen from the inhaled air diffuses through the walls of the alveoli and into the surrounding capillaries. This oxygen binds to hemoglobin in red blood cells, forming oxyhemoglobin. The oxygenated blood then travels to the heart, which pumps it to the rest of the body.

Simultaneously, carbon dioxide produced by your cells is carried by the bloodstream to the alveoli. In the alveoli, carbon dioxide diffuses from the capillaries into the air. When you exhale, the carbon dioxide is expelled from your body.

In addition to oxygen and carbon dioxide, gas exchange also involves the exchange of other gases, such as nitrogen and trace amounts of other gases present in the air.

Overall, the process of gas exchange ensures that oxygen is delivered to the cells of your body and carbon dioxide, along with other waste gases, is removed efficiently.
