 LUNGS

✳The lungs are the main organ in the respiratory system.

✳The lungs are located in the airtight thoracic chamber which is formed dorsally by the vertebral column.

✳Lungs are covered by a double layered membrane called the plueral membrane  and contains plueral fluid between them to reduce friction and protects the lungs from mechanical pressures.

✳Each lung contains millions of tiny balloon like structures called alveoli , which are the primary site for gaseous exchange.
