ANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -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-3: -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-4: -This large surface area is necessary to process the huge amounts of air involved in breathing and getting oxygen to your lungs. Your lungs take in about 1.5 gallons (gl) or 6 liters (L) of air per minute.

Detailed explanation-5: -It seems impossible, but if the lungs were opened flat, they would be so big that they would cover the size of a tennis court. Study finds bronchiectasis patients have a higher risk of cardiovascular disease.
