The answer to this question is A. The respiratory system is in charge of the gas exchange between the external environment and the body’s circulatory system. The respiratory system is composed of different organs but the primary organs are the lungs.

The lungs are in charge of making the exchange of gases possible. It gets oxygen that is spread throughout the body. In return, carbon dioxide is removed from the body. The carbon dioxide will be useful to living things that are responsible for producing oxygen namely the trees and plants. This explains why people need to be surrounded by more trees. They are in charge of providing the air we need to live for free.

The answer to this question is A. This means that the respiratory system is in charge of the gas exchange between the environment where the person is located and the air that the person breathes out. People need to have oxygen in order to survive. Oxygen is acquired from trees.

Once the gas exchange is complete, people breathe out carbon dioxide. This is the type of air needed by plants in order to survive. Respiratory problems signify that people usually have a hard time breathing. Asthma is one example of a respiratory disease and it can be serious if people do not get the treatment they need immediately.
