Difference Between Breathing and Respiration Explained Simply

23 May 2026 · Dheeraj

Breathing and respiration are two things that keep us alive. A lot of people think they are the thing because they are connected. In biology breathing and respiration are not the same. Knowing the Difference Between Breathing and Respiration helps people understand how our body gets oxygen and makes energy.

In other words, breathing is when we take air into our lungs and then push it out. Respiration is what happens inside our cells where our body makes energy from the food we eat.

Understanding the Basics of Breathing and Respiration

Before learning about respiration vs breathing, it is important to understand each process separately.

What is Breathing?

Breathing is basically just us taking in air and letting it out through our lungs Pulmonary ventilation is another name for it Breathing helps our bodies get oxygen adn get rid of carbon dioxide

Breathing goes on non-stop from the moment we’re born until we pass away If you didn’t breathe, your body wouldn’t get enough oxygen to keep you alive

Main Functions of Breathing

Taking oxygen into the lungs
Removing carbon dioxide from the body
Helping maintain normal body functions
Supporting energy production indirectly

Process of Inhalation and Exhalation

Process of Breathing In and Out. Breathing has two parts:

Inhaling Exhaling Inhaling is when we breathe air into our lungs. Exhaling is when we breathe air out of our lungs. When we inhale: When we exhale: The diaphragm goes down The diaphragm. Goes back up The chest gets bigger The chest gets The air pressure inside the lungs gets Air with lots of carbon dioxide moves out Air with lots of oxygen comes into the lungs We breathe out carbon dioxide- air We breathe in oxygen-air

This back-and-forth movement of air is crucial for staying alive. The process of inhalation and exhalation, breathing in and out keeps us alive.

What is Respiration?

People often wonder, what is respiration. Respiration is something that happens inside the cells of our body. The energy that is made is stored as something called ATP, which’s short for Adenosine Triphosphate. Our body cells use this energy to do all sorts of things like move grow and fix themselves. Respiration is different from breathing. Breathing is something we do with our lungs. Respiration happens deep down inside our cells.

Main Functions of Respiration

Producing energy, for our body
Supporting the things our cells do
Helping our muscles work the way they should
Maintaining the temperature of our body

Respiration is really important because it helps our body make energy. Our body needs energy to do everything. Respiration is a big part of that. Respiration is what makes it possible for our cells to do their job

Stages of Cellular Respiration

Cellular respiration happens in three stages.

Glycolysis

This stage happens in the cells cytoplasm.

In glycolysis:

Glucose breaks down into pyruvate.
A small amount of ATP is made.

Krebs Cycle

This stage takes place inside the mitochondria.

In the Krebs Cycle:

Pyruvate breaks down some more.
Carbon dioxide is released.
More energy molecules are made.

Electron Transport Chain

This is the stage of cellular respiration.

In this process:

Oxygen helps make a lot of ATP.
Water is formed as a result.

Difference Between Breathing and Respiration

The Difference Between Breathing and Respiration is among the most studied biology topics by people today.

Parameter Breathing Respiration Definition Physical process of inhaling and exhaling air Biochemical process of producing energy Process Type Mechanical Chemical/Biochemical Location Lungs Cells and mitochondria Main Function Gas exchange Energy production Oxygen Role Brings oxygen into body Uses oxygen to release energy Byproducts No energy produced Carbon dioxide and water Control Mechanism Controlled partly by brain and voluntarily Automatic cellular process Energy Production Uses little energy Produces large amounts of ATP Occurs In Respiratory system Every living cell Importance Supplies oxygen Provides energy to cells

Respiration vs Breathing: Key Points

So I want to go over some things about respiration vs breathing.

Here are the main points:

Breathing is something that happens outside of our body. Respiration is something that happens inside of our body.
The place where breathing happens is in our lungs.
On the hand respiration happens in the cells of our body.
Breathing is about moving air in and out of our lungs.

Respiration is about our cells using oxygen to release energy from the food we eat.
We can think of breathing as a process.
Respiration is more like a chemical process that happens inside our cells.

So to sum it up, respiration vs breathing is an important thing to understand and respiration and breathing are two different things.

Aerobic vs Anaerobic Respiration

There are two kinds of respiration.

Aerobic Respiration

Aerobic respiration needs oxygen to work.
The difference between aerobic and anaerobic respiration is pretty clear

Features of respiration:

Aerobic respiration makes a lot of energy for the cells
Aerobic respiration happens in most cells of the human body
Aerobic respiration releases carbon dioxide and water as waste
The process of respiration can be written as:

C_6H_{12}O_6 + 6O_2 → 6CO_2 + 6H_2O + Energy

Anaerobic Respiration

Anaerobic respiration does not need oxygen to happen.

Features of respiration:

Anaerobic respiration makes less energy, for the cells
Anaerobic respiration happens when we do very intense exercise
Anaerobic respiration makes acid in the human body

Breathing and respiration are really important, for life.

Both breathing and respiration are necessary for survival.

The Importance of Breathing

Breathing is very important because it does a lot of things for our body.
It gives our body the oxygen it needs.
It gets rid of the carbon dioxide.
Breathing also helps keep our lungs healthy.

The Importance of Respiration

Respiration is also very important because it helps our body in ways.

It makes energy for us to do things.
It helps our brain and muscles work properly.
Respiration also helps our cells grow and get fixed when they are damaged.
Without respiration our cells would not have energy to survive.
Our body would not be able to do anything without breathing and respiration.
Breathing and respiration are really necessary for our body to work properly.

Real-Life Examples to Help You Understand

Understanding Breathing and Respiration is easy when you see real-life examples.

Example 1

When you run fast
your breathing gets faster.

This is because your cells need oxygen for Respiration.

Example 2

When you are sleeping
Breathing keeps happening on its own.

At the time Respiration keeps giving you energy.

Example 3

When you are exercising
your muscles use energy.
This makes Respiration happen faster.
Breathing also gets faster.

Common Mistakes people Make About Breathing and Respiration

Many people get confused because both breathing and respiration involve oxygen.

Common Mistakes – Thinking breathing and respiration are one and the same thing

Believing respiration happens in the lungs
Assuming that breathing gives us energy
Getting inhalation mixed up with respiration

You should remember: Breathing is about moving gases in and out while respiration is, about releasing energy from the food we eat.

Conclusion

Once one understands how to Difference Between Breathing and Respiration, it becomes very easy to see both processes as being interrelated, as we need to have both of these processes in order to survive. Breathing is defined as the physical act of taking in and expelling air from our lungs and is a vital function for survival because it provides our body with the oxygen it needs so we can perform our daily activities.

Respiration is defined as a chemical reaction that utilizes the oxygen that was inhaled via the lungs to produce energy at a cellular level. When people gain an understanding of respiration vs breathing, they develop an understanding of how biology is built around both of these processes.

Frequently Asked Questions

Why is breathing important for the human body?

Breathing is important because it supplies oxygen to the body and removes carbon dioxide. Without breathing, the body cannot survive.

Where does breathing take place?

Breathing takes place in the lungs and respiratory organs such as the nose, trachea, and diaphragm.

Why is respiration important?

Respiration is important because it produces energy for all body functions like movement, growth, repair, and brain activity.

Why does breathing become faster during exercise?

Breathing becomes faster during exercise because the muscles need more oxygen for respiration and energy production.

Does breathing produce energy?

No, breathing itself does not produce energy. It only helps bring oxygen into the body. Respiration is the process that produces energy.
