Our ability to oxygenate the tissues and organs of our bodies depends on our ability to ventilate, or exchange gases in our respiratory system. The resultant distribution of ventilation in our respiratory system depends on what factors?

Explanation:

Ventilation is defined as the exchange of air between atmosphere and the lungs so that the carbon dioxide in the alveoli (the small gas sacs in the lungs) can be exchanged.

Factors affecting distribution of air in respiratory system while ventilation are as following:

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
