Immunology is the branch of biological and medical sciences that studies the immune system, which is the body’s defense mechanism against harmful organisms, pathogens (like bacteria, viruses, fungi, and parasites), and other foreign substances. Immunologists work to understand how the immune system functions in both health and disease, including autoimmune disorders, hypersensitivities (like allergies), immunodeficiencies, and the immune response to infection.
