Gas exchange affects all processes of the body because everything in the body requires the gas exchange process to occur. The following are the interrelated concepts with gas exchange according to Giddens (2017); acid-base balance, anxiety, perfusion, nutrition, mobility, and fatigue. Acid-Base Balance is affected in a variety of different ways by gas exchange. For example, with chronic respiratory conditions such as COPD it causes respiratory acidosis which is essentially an increase in carbonic acid and a decrease in pH. Then the opposite would be when you breathe off too much carbon dioxide, this causes respiratory alkalosis because it is a decrease in carbonic acid and an increases in pH. The next interrelated concept is perfusion;
