Explanation:

(1.)  The pleura is a two-layer membrane that covers the lungs and lines the chest cavity. The area that contains pleural fluid is known as the pleural space. Normally, there is a small amount of pleural fluid in the pleural space. The fluid keeps the pleura moist and reduces friction between the membranes when you breathe.

(2.)  The alveoli cover a surface that measures more than 1,076.4 square feet (100 square meters). This large surface area is necessary to process the huge amounts of air involved in breathing and getting oxygen to your lungs
