Respiration System

Respiration

Every human needs the air that contains oxygen for breathing. Without it, we won’t life and we can’t do our daily activity. But, have you ever thought about the process of respiration?

First, the air enters through our nose. In the nose, it will be warmed by mucus membrane and it also will be cleaned by the soft hairs in the nose. After that, it flows through the throat, larinks, and trachea. And if there’s a strange thing which is brought by the air, it will be refused by a web which is located in trachea. Then, the air flows throught a branch of broncus called bronchiolus. The last, it enters into abranch of bronchiolus called Alveolus. Alveolus is collection of collection of the lung’s buble an it’s a place were the cange between oxygen and carbon dioxide happens.

That’s the process of respiration that we do all the the time because we are the living creature.
