What is the difference between the outer and inner pleural membrane in the respiratory system?
Options
- AOuter pleural membrane regulates body temperature while inner pleural membrane reduces friction
- BOuter pleural membrane reduces friction while inner pleural membrane regulates body temperature
- COuter pleural membrane is in close contact with the lung surface while inner pleural membrane is in close cont
- DOuter pleural membrane is in close contact with the thoracic lining while inner pleural membrane is in close c
Correct answer
D. Outer pleural membrane is in close contact with the thoracic lining while inner pleural membrane is in close c
Step-by-step solution
The outer pleural membrane is in close contact with the thoracic lining. whereas the inner pleural membrane is in contact with the lung surface. The part starting with the external nostrils up to the terminal bronchioles constitute the conducting part whereas the alveoli and their ducts form the respiratory or exchange part of the respiratory system. The conducting part transports the atmospheric air to the alveoli, clears it from foreign particles, humidifies and also brings the air to body temperature. Exchange p
