Oxygen (O2).
Astronauts on the space station breathe a mixture of oxygen and nitrogen, similar to the air we breathe on Earth. The station has systems that generate and maintain this breathable atmosphere, including equipment to produce oxygen from water and remove carbon dioxide exhaled by the astronauts.
Astronauts use compressed oxygen mixed with nitrogen fo produce their breathing gas.
Oxygen is used to help people breathe in and out
the gas mask is important because if you are somewhere when you cant breathe they will help you breathe
Astronauts breathe in a mixture of gases, primarily oxygen and nitrogen, similar to Earth's atmosphere. However, in spacecraft and space stations, the atmosphere is typically enriched with oxygen, around 21% to 30%, to ensure safety and comfort. The primary gas they breathe is oxygen (O₂), which is essential for respiration. Carbon dioxide (CO₂) is also present, but it must be carefully monitored and removed from the environment to maintain a safe atmosphere.
Oxygen is the gas we breathe that helps our body get energy from food through a process called cellular respiration. In this process, oxygen is used to break down glucose from food into energy that our cells can use.
The gas that we don't use in our lungs we breathe out again.
You put it on your face and you wear it. Then you breathe into it.
The same air that we breathe !!
Carbon dioxide is the gas you breathe out the second most. Oxygen is the gas you breathe out the most.
Oxygen is the component of air that we consume, so it must be continuously replaced as the astronauts breathe it. The the other components of air, mostly nitrogen, simply come from the initial air supply and do not need to be replaced.
Oxygen is the gas we breathe. It is colorless, odorless, and tasteless. It is essential to humans' survival.
