Fun Fact 1: What are lungs? Lungs are part of the respiratory system; the respiratory system is made up of the trachea, the lungs and the diaphragm. The purpose of the respiratory system is to breathe to circulate oxygen into the body

Fun Fact 3: Where are the Lungs in the human body? Humans have two lungs, they are situated below the trachea (the windpipe) and above the diaphragm; they are protected by muscles and the rib cage

Fun Fact 4: Lungs are filled with over 300 million tiny air bags called alveoli. The alveoli carry oxygen into the blood stream and remove carbon dioxide which is exhaled in our breathe

Fun Fact 5: How big are Lungs? Lungs vary in size just as people do, generally adult lungs measure around 25 - 35 cm long, 10 - 15 cm wide and weigh 0.8 - 1.2 kg. The left lung is slightly smaller than the right to allow room for the heart
