Detailed explanation-1: -Carbon dioxide is released by the body that needs to breathe it out, so it can be harmful if it builds up in the bloodstream.

Detailed explanation-2: -What can you infer about carbon dioxide from the fact that your body needs to breathe it out? It is necessary for a variety of life processes. It can be harmful if it builds up in the bloodstream. Without it, the lungs would not be able to function.

Detailed explanation-3: -Symptoms of mild CO2 exposure may include headache and drowsiness. At higher levels, rapid breathing, confusion, increased cardiac output, elevated blood pressure and increased arrhythmias may occur. Breathing oxygen depleted air caused by extreme CO2 concentrations can lead to death by suffocation.

Detailed explanation-4: -A high carbon dioxide level can cause rapid breathing and confusion. Some people who have respiratory failure may become very sleepy or lose consciousness. They also may have arrhythmia (irregular heartbeat). You may have these symptoms if your brain and heart are not getting enough oxygen.

Detailed explanation-5: -A high concentration can displace oxygen in the air. If less oxygen is available to breathe, symptoms such as headache, rapid breathing, rapid heart rate, clumsiness, emotional upsets and fatigue can result. As less oxygen becomes available, nausea and vomiting, collapse, convulsions, coma and death can occur.
