What Is Respiration?
Respiration overall is how things breathe. Respiration is when we inhale and exhale and the exchange of oxygen from the body. The respiratory cycle is the cycle that all living things go through to create or generate energy for their bodies. This process normally exchanges the gases carbon dioxide and oxygen from the body. The respiratory system is mainly controlled by a part in your brain called the cerebellum and it is located at the bottom of the brain and it controls the way you use your respiration. If your brain does not have oxygen supplying it, you could die in moments from oxygen deprivation.

How Does Respiration work?
Respiration has many ways of working through the body. One way that respiration works is when you inhale you get all of this oxygen and there are two main circulatory systems that supply all of the oxygen to the body. The first circulatory system supplies all the cells with oxygen and blood. The other circulatory system supplies thelungs, veins and other organs with blood and oxygen. When cells make energy for your body to use it is called cellular respiration. Your body needs cellular respiration to have energy for your body. This process happens when you eat food and your body generates molecules that cellular respiration turn into energy. Glucose is something that all of our organs and bodies need to live healthily.

Oxygen
The reason we have respiration is because we need oxygen to live. Oxygen is made up of 78 percent of nitrogen, 21percent oxygen, very little carbon dioxide and other gases in the oxygen we breathe. When we inhale we have all of the nitrogen and oxygen and carbon dioxide even though we don’t need them. When we exhale all of the nitrogen and carbon dioxide is put back into the atmosphere and your body keeps the oxygen. The reason our body keeps the oxygen, not the carbon dioxide, is because all of our organs need oxygen not carbon dioxide. Photosynthesisis when plants take carbon dioxide and make food for themselfs. Our body can go a maximum of 10,000 feet before our body cannot breathe and there is a high chance you could die. Our brain needs oxygen to live.


How Does Oxygen move Though the Body
Oxygen has many ways of moving though the body. The respiratory system is responsible for taking the oxygen from the atmosphere and giving it to the lungs and heart to give to the blood, which helps the oxygen move though our body. There is another thing that helps the process it is called diaphragm. This little organ is located close the lungs and helps pump all the carbon dioxide into the lungs to be exhaled. The oxygen and carbon dioxide exits and enters the body by the nose and mouth. When your blood is pumping, it is getting rid of all the carbon dioxide which takes it to the lungs to be exhaled.



Glossary :
Carbon Dioxide: A gas that you inhale and your body exhales
Circulatory system: The system that makes your blood move around your body in your veins.
Diaphragm: A small muscle that helps pump the carbon dioxide out of the body.
