WebBreathing occurs usually involuntarily, i., not under our control. The normal respiratory rate of a child decreases from birth to adolescence. A child under 1 year of age has a normal respiratory rate between 30 and 60 breaths per minute, but by the time a child is about 10 years old, the normal rate is closer to 18 to 30. WebThe Mechanism of Breathing. Breathing is a vital process that is essential for life. It enables us to exchange oxygen and carbon dioxide within our bodies and is the basis of all metabolism. The mechanism of breathing involves a complex set of muscles and organs that work together to move air in and out of our lungs. increase in psa
