Surfactant is an essential substance in our lungs that helps to mix and distribute air in our respiratory system. It plays a crucial role in regulating gas exchange, which occurs when oxygen enters our bloodstream and carbon dioxide leaves it.

The process by which surfactant works in the lungs involves several steps:
1. Inhalation: When we breathe in, the air enters our lungs through a bronchi. At the end of each bronchus, there is a large smooth muscle called a mucus cell, which produces mucus.
2. Mucus formation: As the air enters the lungs, it combines with mucus cells produced by the mucus cell in the bronchi. This mixture becomes thick and sticky, which makes it difficult for air to flow freely through the lungs.
3. Gas exchange: The thick mucus material produced by the mucus cell in the bronchi helps to slow down the rate at which air flows through the lungs. This slows down the movement of carbon dioxide out of the blood and allows oxygen to enter the bloodstream more easily.
4. Exhalation: As the lungs start to empty out the remaining air, the thick mucus material helps to trap any remaining gases, including carbon dioxide. When we exhale, this trapped carbon dioxide is expelled from the body.

Overall, surfactant is a vital substance in the lungs that helps to regulate the exchange of gases between the bloodstream and the air in the lungs. Without surfactant, the normal process of gas exchange would not be possible, and we would be unable to obtain the oxygen we need to survive.
