Describe how the lungs adapted to their function
- Lungs have numerous alveoli that provide a large surface area for efficient gaseous exchange;
- Has alveoli with thin epithelium to shorten diffusion distance for rapid exchange of gases;
- It has alveoli that are highly vascularised to efficiently transport respiratory gases to and from the body tissues respectively;
- Lungs are covered with pleural membrane which is air-tight thus changes in pressure within the lungs can occur without external interference;
- They have alveoli with moist lining to dissolve diffusing respiratory gases.
