The respiration process

I think of human's breathing. The breathing is important in our life. If I just do not breath for 5minutes. I can be bearable, but more 5 minutes I will be die,because of breathing. All living things are breathing of their part of lungs, gills, skin, and cell surface. Some living things are living in sea or land. The mammals are breathing in lungs, the fish are breathing by gills, and the earthworms are breathing in skins. Amoeba is breathing in cell surface. Oxygen is very important in our life. If the oxygen is not in our life, we cannot breathing in earth. That is my summary of the living thing's breathing. Fish- Breathing by gills.



Cat- Breathing by lungs

Earthworm- Breathing by skins
