9Ba4 Organ systems
System
Main organs
Function
respiratory (or breathing)
digestive
circulatory
skeletal
There are seven organ systems altogether.
Name one other system apart from the ones mentioned above.
How do famous sports people stay healthy?
What is respiration?
How do things make energy?
oxygen + glucose  water + carbon dioxide (+ energy)
For all your cells to be able to respire, three organ systems need to be working
well: the respiratory (or breathing) system, the digestive system and the
circulatory system. Using the information and the diagram on this sheet, write
two or three paragraphs to clearly explain how your cells get the raw materials
that they need to respire. Use as many scientific words as you can.

• Evaluation:
Smoking!!
Smoking and breathing
Cilia sweep mucus and
trapped debris up to
the throat where it is
swallowed.
Hot gases in cigarette smoke paralyse the cilia
so mucus builds up in the bronchioles.
Epithelial cells and smoking
• The lungs are moist, have a big
surface and are very thin, so
that….
• The ciliated epithelial cells in the
lungs…….
• The goblet cells….
• The smoke particles from cigarettes …..
• The tar in the some ……
• The nicotine is poisonous drug that….
What is a drug??
Harmful chemicals
Cigarette smoke contains many harmful substances:

harm an unborn embryo.
How did we find out smoking was harmful?
Graphs like this show correlations, or patterns,
but they don’t prove it was smoking that
affected the health of these people.
