Answer:
The term describes cellular respiration 
Explanation:
Cellular respiration, also known as internal or tissue respiration can be represented by the equation:
C6H12O6 + 6H2O ---> 6H2O + 6CO2 + Energy (in form of ATP)
From the equation, glucose from the blood is oxidized by oxygen trapped from the air by the nostrils. The main purpose of cellular respiration is to generate energy required by the body for various life activities
