What respiration & breathing means

You learn how the body takes in oxygen and removes carbon dioxide during breathing. This matters because living things need respiration to release energy for movement, growth, and other body activities.

What you will practise

  • Identify the gas you breathe in for respiration
  • Name the gas breathed out in larger amounts
  • Match gaseous exchange to the lungs
  • Link breathing to the release of energy
  • Choose correct answers about human respiration

Before you start

You should already know that humans breathe using the chest and lungs. It also helps if you can name common gases in air.

Not confident yet? Work through The digestive system first.

Worked example

One question from this skill's own question bank, shown with its full working.

Question

Which gas do we take in when we breathe in?

  • carbon dioxide
  • oxygen
  • nitrogen
  • hydrogen
Answer: oxygen

Working: We breathe in air rich in oxygen, which the body needs for respiration.

Common mistakes to avoid

  • Thinking carbon dioxide is the gas taken in. Remember oxygen enters the body for respiration.
  • Confusing breathing with respiration. Breathing moves air, while respiration releases energy in cells.
  • Saying gaseous exchange happens in the stomach. It takes place in the lungs, not the digestive system.
  • Mixing up the main gases. Learn that oxygen is taken in and carbon dioxide is breathed out.
