The two main types of immunity in the body are innate immunity and adaptive immunity. Innate immunity is the body’s first line of defense, providing a broad and immediate response to pathogens through physical barriers, like skin, and immune responses involving cells like macrophages. Adaptive immunity, on the other hand, develops over time and involves a specific response to pathogens, utilizing lymphocytes such as T cells and B cells to create long-lasting immunity. Both types are crucial for a comprehensive immune response against infections and diseases.
