The Respiratory System
- At rest, we breathe 15 to 20 times a minute and exchange nearly 17 fluid ounces (about 500 milliliters) of air with each complete breath in and out.
- Approximately 5 fluid ounces (about 150 milliliters) of the air we breathe in with each breath fills the passageways of the trachea, bronchi, and bronchioles.
- We breathe over 5,000 times a day, taking in enough air throughout a lifetime to fill 10 million balloons.
- The average set of human lungs has approximately 600 million alveoli (300 million per lung), creating a respiratory surface about the size of a singles tennis court or a square about 27 to 28 feet long on each side.
- At birth, an infant’s lung is estimated to have approximately 20 to 30 million alveoli and 1,500 miles of airway passages.
