Immune response is the body’s coordinated and complex defense mechanism against foreign substances and microorganisms. It includes two main types of responses – innate and adaptive.
1. Innate response: The innate immune response is the rapid, non-specific, and immediate response to foreign invaders. It includes physical and chemical barriers such as skin, mucous membranes, and cilia, as well as immune cells like neutrophils, macrophages, and natural killer cells. The innate immune response is always active and does not require any previous exposure to the invader.
2. Adaptive response: The adaptive immune response is a slower and more specific response. It is tailored to the specific invader and requires previous exposure to the invader. Adaptive immunity includes B cells, T cells, and antibodies. B cells produce antibodies that circulate in the blood and recognize specific pathogens, while T cells recognize and kill infected cells directly.
Together, the innate and adaptive immune responses work to clear the body of foreign substances and microorganisms, providing protection against infections and diseases.
