AQA Unit 1: Chapter 4: Lungs and Lung Disease

Powerpoint presentation that uses the specification per slide, uses information from the textbook. I have got word document notes (in a more Q & A style) that go with it if your interested (just ask). Don't know how useful this is, but if it turns out to be, i've got a tonne more.

I tend to work visually so this is why it works well for me. Works with the textbook, not instead of.

Here's a taster:

The gross structure of the human gas exchange
system limited to the alveoli, bronchioles, bronchi,
trachea and lungs.
Trachea: flexible airway supported by rings of
cartilage preventing trachea collapsing when air
pressure inside falls when breathing in.
Ad:
-Walls made of muscle lined with ciliated
epithelium/goblet cells which produce mucus that
trap dirt and bacteria
- Cilia move mucus + dirt + microorganisms throat,
esophagus stomach
Bronchi: are 2 divisions of trachea each leading to
one lung. Large bronchi are supported by cartilage.
Ad : produce mucus to trap dirt particles and have
cilia.
Bronchioles: series of branching subdivisions of
bronchi.
Ad: Walls made of muscle lined with epithelium
cells allows them to constrict to control flow of air
for alveoli…read more
