Final answer:
The smaller the service area does not necessarily make gas exchange faster.
Step-by-step explanation:
The statement "the smaller the service area the faster the gas exchange" is false.
Gas exchange occurs in the respiratory system through the process of diffusion, where oxygen moves from an area of high concentration to an area of low concentration.
The rate of diffusion is determined by factors like the surface area available for exchange, the concentration gradient, and the thickness of the barrier.
A larger surface area allows for more efficient gas exchange, as there are more sites for diffusion to occur.
