How you appreciate the mechanism of respiration in our body? (AS6)

1. Respiration is a necessary life as it provides energy to carry out all the life processes which are necessary to keep the organism alive.

2. The energy that is obtained from respiration is used to build the organism through cell growth and reproduction as well as cell repair.

3. All systems in a living being need energy to survive. Energy is defined as the ability to do work. So without respiration we would not have any energy to perform necessary day-to-day functions.

4. During respiration, carbon dioxide is given out which is a toxic gas. But the carbon dioxide is used by green plants to make food (photosynthesis).

5. The respiratory system goes into operation from the movement of our birth to death.
