This is so useful! I thought I needed to know all the symptoms/causes of each disease. You will save me a lot of time :)

Hi, do we have to memorise the pulmonary ventilation formula?

Hi. I was wondering if you could help. All the three diseases, fibrosis emphysema and asthma their FEV1 is reduced. Because at the alveoli, theres is decrease in concentration gradient which would affect the co2 going out so FEV1 would be affected for all.

And FVC Would also affect asthma, Fibrosis and emphysema because in asthma if less air is getting into the lungs at slower rate than the volume of lings reduces. So probably affects FVC of all. I don’t understand the FEV AND FVC for the diseases. And the way it’s assessed in EQ it confuses me. Example oke question was on how Fibrosis FVC is affected but asthma FVC is not affected. I dont get why. Can u plz explain. Thanks!! :)))

9:17 I'm confused as to what you mean when you say the data overlaps

Idk

is this calculation still required in the new spec?

The spec also says students should be able to evaluate the way in which experimental data led to statutory restrictions on the sources of risk factors. What does this mean? And great video!!
