Final answer:
Another word for 'tubercle' is 'granuloma,' which is a small lesion that forms as part of the immune response in diseases like tuberculosis.
Step-by-step explanation:
The term 'tubercle' refers to a small round lesion typically formed during the immune response to infections such as tuberculosis. Tubercles are the result of an accumulation of neutrophils and macrophages and are encased within a granuloma shell. When a granuloma breaks down, the tubercle bacilli escape, multiply, and form more tubercles, which may eventually rupture leading to the spread of the infection. So, another word for 'tubercle' is A. Granuloma.
