Question

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

Answer 1

The co-ordinate efficiently and effective...

Step-by-step 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.
