WebbThe air we breathe in typically consists of about 78% nitrogen gas, about 21% oxygen gas, and less than 1% argon gas and traces of several other gasses. We remove carbon dioxide from the body by breathing out stale air. Because the human lungs extract about 15% of the oxygen we inhale, the air we exhale still contains about 17% oxygen. Webb30 jan. 2015 · The oxygen in the atmosphere was produced by cyanobacteria during the Great Oyxgenation Event, around 2.3 billion years ago. Cyanobacteria produced & still, produces, to a lesser extent, oxygen by photosynthesis.

WebbTowards the end of development, the fetus can be observed making breathing movements.

Breathing (or ventilation) is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen. All aerobic creatures need oxygen for cellular respiration, which extracts energy from the reaction of oxygen with molecules derived from food and produces carbon dioxide as a waste product. Breathing, or "external respiration", brings air into the lungs where gas exchange takes place in the
