Human Immunology

Human immunology is the study of the immune system, which protects the body from harmful invaders like bacteria, viruses, and other pathogens. The immune system consists of various cells, tissues, and organs that work together to recognize and eliminate these threats. When the body encounters a pathogen, it triggers a response that can involve antibodies, which neutralize the invaders, and immune cells, which attack and destroy them. A healthy immune system can remember past infections, allowing for quicker responses to future exposures. Immunology helps us understand diseases and develop vaccines and treatments to enhance our body's defenses.
