Section 3: Lungs

Write a short description of the lung regarding their structures and relate them to the function. The sections of lungs are full of gaps, and can often look “messy”. What are these gaps? And what is it that surrounds the “gaps”? (i.e. delineates them)? How can you tell what it is that surroundsthe gaps (or, put another way: what structure within the things that surrounds the gaps tells you what these “things” are?) Aim to write this within 100 words.
