How do the external structures of the respiratory system coordinate with the internal structures of the respiratory system in the process of respiration?

The co-ordinate efficiently and effective...

Explanation:

Well...it is a type of antagonistic mechanism based of Dalton's Law for PArtial Pressures. We take in O2 and Exhale CO2 very effectively because the partial pressure of oxygen is higher outside and lower inside lungs and vice versa for CO2. when the Air with 21% O2 content enter the lungs, the Alveoli that are special sacs filled with air absorb some of it through their membranes and by a process called membrane diffusion of gases. The Air with 16% O2 content is exhaled out by the antagonistic action of lungs and Diaphram muscles combined.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
