Detailed explanation-1: -Breathing is a physical process of taking air from the atmosphere into the body. It also involves expelling spent air back into the atmosphere from the body. Respiration is the chemical process of using oxygen to break down glucose to release energy.
Detailed explanation-2: -The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
Detailed explanation-3: -Respiration is the chemical process by which organic compounds release energy. The compounds change into different ones by exergonic reactions.
Detailed explanation-4: -External respiration is a physical process during which oxygen is taken up by capillaries of lung alveoli and carbon dioxide is released from blood.
Detailed explanation-5: -Breathing occurs through respiratory organs, including the nose, lungs, etc. Respiration takes place in cells and cell organelles, including mitochondria, etc. From the differences given, we can conclude that breathing and cellular respiration are two different processes and cannot be used interchangeably.
