Parasitology is the study of parasites, which are organisms that live on or in another organism and depend on it for survival. Medical parasitology specifically focuses on parasites that infect humans and cause diseases, involving their identification, biology, epidemiology, and potential treatments. It plays a crucial role in diagnosing and managing parasitic infections in patients.
