Difference Between Breathing and Respiration

Difference Between Breathing and Respiration

In order to exist, all living species must execute the involuntary acts of breathing and respiration. Scientifically speaking, breathing and respiration are two distinct bodily processes. We use breathing as a synonym for respiration in our everyday speech.

This is a common misunderstanding, owing to the fact that the same organs, such as the lungs, nose, and mouth, are involved in both breathing and respiration. Because they both have to do with our body’s utilization and intake of oxygen, we tend to lump them together. They are, in fact, rather different.

Breathing Vs. Respiration

Breathing and respiration serve different purposes. Breathing is the process through which humans take in oxygen and expel carbon dioxide via the nose and mouth. Respiration, on the other hand, is a chemical process. Glucose is broken down by the body’s oxygen during breathing.

Energy is produced in the cells of our bodies as a result of the breakdown of glucose. We are able to carry out our everyday routines thanks to this source of energy. In spite of their similarity, breathing and respiration are two distinct processes. It’s true that respiration is a chemical process, not a physical one like breathing. Respiration is a result of the act of inhaling and exhaling.

Every day, we can get things done by breathing. When we breathe, our organs are in good working order.


Breathing is the exchange of gases between the cells of a living organism and the surrounding environment. You breathe by taking in oxygen and exhaling carbon dioxide via your lungs.

There is an inhalation and an exhalation owing to the contraction and relaxation of the muscles, respectively. A person’s mouth, nose, and lungs all play an important role in the process of inhaling and exhaling air.

The diaphragm relaxes during the exhale of carbon dioxide, which causes the thoracic cavity to shrink.

The lungs contract as a result of the increased internal pressure, causing the air to be expelled from the body.

We contract our lungs when inhaling, which causes the ribcage to rise and expand.

This causes the lungs to expand, allowing us to inhale via the nose and mouth. The air then enters the lungs through the windpipe.

Eupnoea, diaphragmatic, hyperpnea, and costal breathing are all forms of breathing.

Breathing Patterns

Slow breathing is the sort of breathing that is described like this. Resting is when it occurs. It’s not something you can control.

Acute hyperpnoea

When there is a dearth of oxygen in the body, this sort of breathing happens. After a strenuous exercise, for example, you may find yourself struggling to breathe.

Diaphragmatic third-person voice

A contraction of the diaphragm causes this sort of breathing to occur. The chest does not move while breathing; rather, the belly conducts the work. Abdominal action is clearly obvious.

4th Coast

It’s also known as “shallow breathing,” because it requires the contraction of the intercostal muscles. A person’s inhalation relies mostly on the intercostal muscles.

The ribcage is utilized for both inhalation and exhalation in costal breathing.


You breathe in oxygen and expel carbon dioxide and other gases via respiration, which is also known as gas exchange.

In order to generate energy, oxygen is needed in the breakdown of glucose.

The cells and tissues of the body then employ this energy to carry out the critical activities of the organs and our entire body.

Respiration is a cellular and mitochondrial chemical reaction. Respiration is a complex process involving a large number of enzymes.

Cells develop and repair themselves with the aid of the energy generated during breathing.

Difference Between Breathing and Respiration

  1. Breathing is the process of taking in oxygen and exhaling carbon dioxide, whereas respiration is the process of converting oxygen into energy for the living organisms.
  2. It’s true that respiration is a chemical process, not a physical one like breathing.
  3. Respiration occurs when oxygen breaks down glucose to produce energy, whereas breathing takes place through the nose, mouth, and lungs.
  4. When you’re breathing, you don’t use any enzymes, but when you’re breathing, you do.
  5. Extracellular processes are those that take place outside of cells. As an intracellular activity, respiration takes place inside cells.
  6. Cellular respiration and cellular respiration are two distinct processes.
  7. During respiration, the act of breathing generates a variety of gases, including oxygen, carbon dioxide, and water, which are utilized and expelled.


Breathing and respiration are intertwined, because both are necessary for life. The two processes of breathing and respiration work together to help the body perform its many duties. The bi-products of respiration are released by breathing, which is required for them to exist in the first place.

Even though they are two distinct activities, both are necessary for a live organism’s existence in some way.
