Gas exchange is crucial to sustain life because it rids the body of carbon dioxide and provides oxygen to the body.
Explanation:
Gas exchange in living beings is a mechanism that involves the incorporation of oxygen (O₂) into the organism and the elimination of carbon dioxide (CO₂). This exchange takes place in the pulmonary alveolus and in cells and tissues.
<em><u>During respiration, the inspired air - loaded with O₂ - is exchanged with the CO₂ contained in the blood, taking advantage of the former and eliminating the latter during expiration</u></em><em>.
</em>
<em>When the oxygenated blood is taken to the tissues, O₂ is passed to the cells, which are deprived of the CO₂ produced by metabolism.
</em>
The reason why gas exchange is crucial for the sustain of life is because it is the mechanism that allows the entry of O₂ necessary for cellular functions, as well as providing a means of CO₂ elimination.
