Q

What is the pathogenesis of TB?

7
Q

Why do only a small proportion of patients progress to active TB?

A

-The body is usually good enough to control the mycobarcterium but when someone is immunosuppressed (AIDS, long term steroids, age), the TB escapes the granulomas and spreads to the apices.

8
Q

Why does active TB spread to the apices of the lungs?
