- 1. Immunology is the study of the immune system, which is our body's defense mechanism against harmful pathogens such as bacteria, viruses, and parasites. The immune system is a complex network of cells, tissues, and molecules that work together to protect the body from infection and disease. Immunology encompasses various aspects, including how the immune system recognizes and responds to foreign invaders, how it develops memory to provide long-term protection, and how dysregulation of the immune system can lead to autoimmune diseases or hypersensitivity reactions. Understanding immunology is essential for developing vaccines, treatments for infectious diseases, and therapies for conditions where the immune system is either overactive or underactive.
