Guida verificata passo dopo passo1
Understand the role of leukocytes (white blood cells) in the immune system. Leukocytes are specialized cells that help defend the body against pathogens, including bacteria, viruses, and parasites.
Learn the specific functions of each type of leukocyte mentioned in the problem: Eosinophils, Lymphocytes, Neutrophils, and Basophils. Each has a unique role in immunity.
Focus on Eosinophils. These leukocytes are particularly effective against parasitic worms. They release digestive enzymes and toxic proteins to attack and break down the parasite's structure.
Compare Eosinophils to the other leukocytes: Lymphocytes are involved in adaptive immunity (e.g., producing antibodies and killing infected cells), Neutrophils are first responders to bacterial infections, and Basophils release histamine during allergic reactions.
Conclude that Eosinophils are the leukocytes specialized for killing parasitic worms by deluging them with digestive enzymes, as described in the problem.
