Question

if all alveoli is almost equal to tennis court so why we are not big like a tennis court
answer me ​

Answer 1

Answer:Each bronchiole is about the same thickness as a hair. At the end of each bronchiole is a special area that leads into clumps of teeny tiny air sacs called alveoli (say: al-VEE-oh-lie). There are about 600 million alveoli in your lungs and if you stretched them out, they would cover an entire tennis court.

Answer 2

the total surface area of the alveoli is very very large-roughly the size of a Tennis Court. The lungs are not equal in size...The left lung is smaller because of the space taken by the heart
