Respiratory
HOT
(A Students)System- Part 2
Learning Objectives: Lesson focuses on the mechanics of breathing
Give the definition of each key word.
Learning Outcome:
A ANALYSE, EVALUATE & APPLY:
I have excellent understanding of how the respiratory system works and can link the respiratory system to the
circulatory system and appreciate the cardio-respiratory system. I can reference how physical activity affects
the respiratory system.
B UNDERSTAND & EXPLAIN:
I understand and can explain how the respiratory system works and demonstrate this in terms of fitness
programs. Label anatomical diagrams, show understanding of functions & mechanics of breathing including
reference to biochemical aspects of respiration (i.e. the use of glucose and oxygen).
C KNOW & DEFINE:
Time for activity
I can define functions of the respiratory system through labelling diagrams and giving examples
of what

page.
happens during inspiration and expiration during rest and exercise.
Starter: What were the 3 key words you had to learn for homework?
Mechanisms of breathing –
inspiration
When you breathe in:
intercostal muscles between
the ribs contract, pulling the
chest walls up and out
Intercostal
muscles pull ribs
up and out
the diaphragm muscle
below the lungs contracts and
flattens, increasing the size of
the chest
the lungs increase in size,
so the pressure inside them
falls. This causes air to rush in
through the nose or mouth.
Diaphragm
contracts and
moves down
Mechanisms of breathing –
expiration
Ribs move in
and down
When you breathe out:
Intercostal muscles between
the ribs relax so that the chest
walls move in and down.
The diaphragm muscle below
the lungs relaxes and bulges up,
reducing the size of the chest.
Diaphragm
relaxes and
bulges up
The lungs decrease in size, so
the pressure inside increases
and air is pushed up the trachea
and out through the nose or
mouth.
Functions of the lungs
1. To allow oxygen into
the blood stream.
2. To allow carbon
dioxide out of the
body
3. Process is called:

Tidal Volume: Revision Tip
• Remember the
waves at the
seaside and
how the they
roll in and out.
• TIDE= TIDAL
Vital Capacity: Revision Tip
• Remember how
VITAL it is to
pass the breath
test
Choose a task
You are a oxygen
molecule. Describe
what your exciting
adventure was like on
your way to the
muscles of the body
B
Describe and explain what happens
when
1. We breathe in
2. We breathe out
List all the key words of the lesson and
write a brief summary of what they are
creating a way for you to remember
them
