Concept explainers
To explain:
Whether pus is from an early or late stage of infection if it contains a large number of macrophages.
Introduction:
Monocytes are the large agranulocytes with somewhat lobed nuclei. By the process of diapedesis, monocytes leave blood and mature into cells known as macrophages. Macrophages are phagocytic cells and they phagocytose foreign substances entering body.
To explain:
The way through which it can be explained that sample of pus is from late stage of infection.
Introduction:
In the present scenario, Person M observed a sample of pus from pimple and she noticed a large number of macrophages in the sample. It can be concluded that the sample is from late stage of infection.
