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. That’s about the distance from Chicago to Las Vegas.
Detailed explanation-2: -The alveoli cover a surface of more than 1, 399 feet (ft) or 130 square meters (m2) . This large surface area is necessary to process the huge amounts of air involved in breathing and getting oxygen to your lungs.
Detailed explanation-3: -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.
