What are your lungs made of?
Question Date: 2013-09-22
Answer 1:

The lungs are the largest organs in the human body and are part of the respiratory system. Both lungs are not identical in shape; the right one is a little bit bigger than the left. Since they need to stretch and constrict, the lungs are made of an elastic tissue. This tissue is made of epithelial cells with specialized hairs; these hairs trap particles and prevent infection from reaching the lungs.
