Detailed explanation-1: -It is estimated that the adult human lung has on the order of 300 million alveoli, with a total surface area approximately the size of a tennis court. The alveoli are thin-walled structures with a total surface area of about 100m2. This is roughly half the size of a tennis court.
Detailed explanation-2: -Your lungs are one of the largest organs in your body. The surface area of both lungs is roughly the same size as a tennis court and the total length of the airways running through them is 1, 500 miles. That’s about the distance from Chicago to Las Vegas.
Detailed explanation-3: -Fun Fact: The total respiratory surface of human lungs is about 100 m2, equal to the surface area of a racquetball court! The feather-like shape of gills also serves to increase respiratory surface area.
Detailed explanation-4: -Large surface area: human lungs contain about 500 million alveoli, which creates a surface area around half the size of a tennis court. This speeds up diffusion because gases have more area over which to diffuse.
Detailed explanation-5: -If stretched out, the total surface area of lungs would be about the same size as half a tennis court. There are about 600 million lung sacs (alveoli) in your lungs.
