Without the presence of oxygen, survival is beyond question. We need a continuous supply of this fresh air to enable all our body parts to function appropriately. We get oxygen from trees and plants. The trees and plants around us inhale carbon dioxide from the atmosphere and exhale the life giving oxygen
Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive. “Rapid cooling of the brain can increase survival time without oxygen,” says Tipton. “If you reduce the temperature by 10 degrees the metabolic rate drops by a half to a third. If you lower the brain temperature down to 30C (86F), it can increase the survival time from 10 to 20 minutes. Any organism which can exist or live without oxygen is called an anaerobic organism or anaerobes. Anaerobic bacteria are also examples of anaerobic organisms, which do not require oxygen for respiration. If your blood has low levels of oxygen, it can't deliver enough oxygen to your organs and tissues that need it to keep working (hypoxia). This can damage your heart or brain if it persists over time (for instance, with nocturnal hypoxemia caused by sleep apnea). Acute cases of hypoxemia can be fatal.
