AQA Biology 1 - Lung Disease

Meant to be a hard quiz, hope it turns out okay!

Any mistakes you see comment them! 
Happy Revision ¬¬ :P 

I'll add some more questions when I've learnt the answers (Y)

?
What is Pulmonary Tuberculosis?
A deadly Bacterial infection normally, but not limited to the lungs.
1 of 6
What does Pulmonary Fibrosis cause in terms of gas exchange?
The thickening of the epithelium increases the diffusion pathway for o2 and co2, reduces volume of air the alveoli can hold and stops the lungs stretching as much as they would in normal ventilation.
2 of 6
Symptoms of pulmonary TB?
coughing up blood.
3 of 6
What is the difference between Mycobacterium tuberculosis and Mycobacterium Bovis in the transmission of Pulmonary Tuberculosis?
Bovis is usually spread from close contact with cows or consuming infected milk. Whereas M. Tuberculosis is spread from person to person via tiny water droplets in the air from infected individuals laughing, talking, coughing etc.
4 of 6
What is Pulmonary Fibrosis?
Scar tissue thickening the thin gas exchange epithelium leading to reduced gas exchange.
5 of 6
What is asthma?
An allergic reaction to allergens or environmental conditions.

I think there is more than just coughing up blood that is a symptom of pulmonary tb? I may be wrong but I'm sure it gives you a persistent cough too, just thought I should mention it :)

tb symptoms also include persistent cough loss of appetite leading to weight loss and tiredness

Im pretty sure that there are more symptoms than coughing up blood for TB, and the asthma question: Asthma is a constriction of the air passageways because of an allergic reaction.

Just thought id mention these to help you

great quiz but asthma is a constriction of the bronchi and bronchioles. Also, the mucous glands go into overdrive and there is inflammation due to the presence of histamines.
