Respiratory System Ventilation ( breathing)
Recap questions, discuss with your partner1. How you know something is alive?2. Why do we breathe?3. Make a list of things we need energy for?4. Can you write the word equation for combustionFuel + ______ 5. Can you write the word equation for respirationGlucose + __________
LO: explain that plants and animals respireCompare and contract combustion and respiration

Releasing energy from food• This is called
RESPIRATIONGlucose + oxygen carbon dioxide + water + ENERGY
This reaction occurs in all living organisms
DEMO: screaming jelly baby
FUEL + OXYGEN combustion

Similar DifferentHow is combustion similar to respiration and how is it different?
Breathe in, breath out
• So how is breathing different to respiration.
Glucose + oxygen carbon dioxide + water + ENERGY
Rib muscles – to raise and lower the ribs
Right lung
Bronchioles- contain air sacs called alveoli
Ribs –protect the chest
Left bronchus
Heart
Diaphragm- muscular sheet
Windpipe- carries air to the chest
Ventilation (breathing) occurs in the lungs it allows useful gases to diffuse into blood
and waste gases to be removed

Breathing is the movement of air in and out of the lungs.
You can see people breathing and it’s one of the first things a doctor looks for to see if someone is alive.
Respiration is a chemical reaction going on inside all living cells.
It releases energy from glucose to keep the body alive.
Are breathing and respiration the same thing???
Demonstrating respiration and breathing.

Cells of the body
Head
Oxygen is taken in by the cells of the body and the head and is combined with glucose to transfer energy to something useful for the body e.g. movement
RESPIRATION
BREATHING
When the lungs takes in oxygen that is needed for respiration and takes out carbon dioxide gas
Role play questions
• What does the blood carry from the lungs to the cells?
• What does the blood carry from the cells to the lungs?
• Where does breathing occur in this roleplay?• Where does respiration occur?
Fish Head Video• Explain with reasons whether the
fish is dead or alive• Are the gills moving?• If the fish is not breathing, why is it
still moving?• When would you determine when a
person/animal is dead?

8B Respiration – the truth, and quite few lies
True or false?
1. Respiration releases energy from glucose.
2. Oxygen is needed for respiration in humans.
3. We die without oxygen because we cannot respire.
4. Respiration is a bit like burning.
5. People do not respire while they are asleep.
6. The more energy we need, the less we respire.

8B Respiration and combustion
Respiration and combustion - same thing? Or not?Are these statements...…only true about respiration? (R)…only true about combustion? (C)…true about respiration and combustion (R & C)
Needs a high temperature (C)Gives out light (C)Happens at room temperature (R)Gives out heat (R & C)Needs enzymes to work properly (R)Uses oxygen (R & C)Gives out carbon dioxide (R & C)
