(NCERT) Class-12th biology notes- Immunity
Immunity is the body's defense system against harmful invaders such as bacteria, viruses, and other pathogens. It consists of two main types: innate and adaptive immunity. Innate immunity provides immediate, non-specific protection. It includes physical barriers like the skin, as well as immune cells that quickly respond to infections.Vaccination is a crucial tool in enhancing adaptive immunity by training the immune system to recognize and fight specific pathogens, thereby preventing diseases. A well-functioning immune system is vital for maintaining overall health and well-being.
