The innate immune system is the body’s first line of defense against pathogens. It consists of physical and chemical barriers that prevent pathogens from entering the body, phagocytic cells that engulf and destroy pathogens, and the inflammatory response that helps to contain and eliminate infections.
Physical and Chemical Barriers: These include the skin, mucous membranes, and antimicrobial substances like lysozymes and stomach acid. They prevent pathogens from entering the body and provide a barrier against infection.
Phagocytic Cells: Cells like neutrophils and macrophages are responsible for engulfing and digesting pathogens. These cells recognize pathogens using pattern recognition receptors (PRRs) and initiate the immune response.
Inflammation: When tissue is damaged or infected, inflammation occurs. This response involves vasodilation, increased permeability of blood vessels, and recruitment of immune cells to the site of infection. Inflammatory cytokines and chemokines are released to enhance the immune response.

Humoral Immunity (B Cells)
Cellular Immunity (T Cells)

The adaptive immune system is the body’s second line of defense, responding to specific pathogens that evade the innate immune response. It involves B and T lymphocytes, each contributing to humoral and cellular immunity, respectively.
Antigens: Antigens are molecules on the surface of pathogens that trigger an immune response. They are recognized by lymphocytes as foreign substances.
B Lymphocytes (B Cells): B cells are responsible for humoral immunity. They produce antibodies that bind to antigens and neutralize pathogens. Memory B cells “remember” the antigen for future responses.
T Lymphocytes (T Cells): T cells are responsible for cellular immunity. Helper T cells (CD4+) assist in activating B cells and cytotoxic T cells (CD8+) that directly attack infected cells.
Humoral Immunity: B cells produce antibodies that circulate in the blood and target pathogens, neutralizing them and promoting their clearance.
Cellular Immunity: T cells, particularly cytotoxic T cells, recognize and destroy infected or abnormal cells, preventing the spread of infections.
By understanding the interplay between the innate and adaptive immune systems, the body can effectively defend against a wide range of pathogens.
