The immune system consists of innate and specific responses, with physical and chemical barriers helping prevent infections. Macrophages, dendritic cells, and the complement system play crucial roles in recognizing and destroying pathogens, while T and B cells create antibodies and memory cells to fight infections.
Insights
The immune system consists of two main components: the innate immune system, which provides a rapid, generalized response to infections through physical and chemical barriers, and the specific immune system, which involves specialized T and B cells targeting specific pathogens.
Key players in the immune response include macrophages, dendritic cells, and the complement system, which work together to recognize, destroy, and signal infections, leading to inflammation and the production of antibodies and memory cells for long-term immunity.
