Breathing vs. Respiration

Breathing:
- Breathing is the process of inhaling and exhaling air into and out of the lungs.
- It is a physical act that involves the movement of the diaphragm and rib muscles to create a pressure difference, allowing air to flow in and out of the lungs.
- Breathing is primarily a mechanical process that helps in the exchange of oxygen and carbon dioxide in the body.
- It is a voluntary action that can be consciously controlled to some extent.

Respiration:
- Respiration, on the other hand, is a chemical process that occurs at the cellular level.
- It involves the breakdown of glucose in the presence of oxygen to produce energy in the form of ATP (adenosine triphosphate), carbon dioxide, and water.
- Respiration takes place in the mitochondria of cells and is essential for the survival of all living organisms.
- It is an involuntary process that is controlled by the autonomic nervous system.

Differences:
- Breathing is a physical act of inhaling and exhaling air, while respiration is a chemical process of producing energy.
- Breathing involves the movement of air in and out of the lungs, while respiration occurs at the cellular level.
- Breathing is a voluntary action that can be consciously controlled, whereas respiration is an involuntary process.
- Breathing is necessary for respiration to occur as it provides the oxygen needed for cellular respiration.
