1. INTRODUCTION: What is the respiratory system?
The respiratory system is the part of your body that helps you breathe in oxygen from the air and breathe out carbon dioxide, a gas your body doesn’t need.
Why is it important?
-
Your cells need oxygen to make energy, so you can think, move and grow.
-
The respiratory system helps you get rid of waste gas (carbon dioxide).
2. VOCABULARY.
HOW WE BREATH:
- Air enters the body and is warmed as it travels through the mouth and nose.
- It then enters the trachea.
- The trachea divides into two bronchi. One bronchus enters each lung.
- Each bronchus branches out into smaller tubes called bronchioles. Air travels through these bronchioles.
- At the end of the bronchioles, the air enters one of the many millions of alveoli where gaseous exchange takes place.

READING:
Respiratory system structure and function. Passage of air into the lungs
Breathing
Breathing is the term given to the process of taking air into and out of the lungs.
Two important structures for breathing are the diaphragm and intercostal muscles.
The diaphragm is a sheet of muscle that separates the chest (or thoracic) cavity from the rest of the body.
The intercostal muscles are found between the ribs and they control rib movement.
Inspiration/ inhalation (breathing in)
The diaphragm contracts and moves downwards. The intercostal muscles contract and move the ribs upwards and outwards. This increases the size of the chest and decreases the air pressure inside it which sucks air into the lungs.
Expiration/ exhalation (breathing out)
The diaphragm relaxes and moves back to its domed shape. The intercostal muscles relax so the ribs move inwards and downwards under their own weight. This decreases the size of the chest and increases the air pressure in the chest so air is forced out of the lungs.
