  7. RISPIROATORY SYSTEM FUNCTIONS • The primary function of the respiratory system is the supply of oxygen to the blood so this in turn delivers oxygen to all parts of the body. The respiratory system does this while breathing is taking place. During the process of breathing we inhale oxygen and exhale carbon dioxide. This exchange of gases takes place at the alveoli. The average adult's lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide follows the same path out of the lungs when you exhale. • To put it simply, the principle functions of the respiratory system are: • Ventilate the lungs • Extract oxygen from the air and transfer it to the bloodstream • Excrete carbon dioxide and water vapour • Maintain the acid base of the blood

  8. Interesting facts • We breathe in over 13 pints of air a minute • Each lung contains 300-350 million respiratory units called alveoli making it a total of 700 million in both lungs. • More than half a litre of water per day is lost through breathing. • People under 30 years of age take in double the amount of oxygen in comparison to a 80 year old. • Yawning brings more oxygen to the lungs
