MICROANATOMY

Detailed explanation-1: -Respiration. Respiration is the act of breathing: Inhaling. The act of breathing in oxygen.

Detailed explanation-2: -The process of breathing, or respiration, is divided into two distinct phases. The first phase is called inspiration, or inhaling. When the lungs inhale, the diaphragm contracts and pulls downward. At the same time, the muscles between the ribs contract and pull upward.

Detailed explanation-3: -Breathing and respiration are not synonymous; breathing is a part of respiration. Breathing refers to the intake of atmospheric oxygen followed by the release of carbon dioxide rich alveolar air.

Detailed explanation-4: -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.

Detailed explanation-5: -External respiration, also known as breathing, involves both bringing air into the lungs (inhalation) and releasing air to the atmosphere (exhalation). During internal respiration, oxygen and carbon dioxide are exchanged between the cells and blood vessels.
