Preparation Staff asked 3 months ago Immunity is the body's natural defense system that protects against harmful pathogens such as bacteria, viruses, and fungi. It is essential for survival, as it helps fight infections and prevents diseases. The immune system consists of specialized cells, tissues, and organs that work together to detect and eliminate harmful invaders. There are two main types of immunity: innate immunity, which provides immediate protection, and adaptive immunity, which develops over time after exposure to pathogens. Vaccination strengthens immunity by helping the body recognize and fight specific diseases. A strong immune system ensures quick recovery from infections and reduces the risk of chronic illnesses. Factors such as stress, poor nutrition, and lack of sleep can weaken immunity, making the body more susceptible to diseases. Maintaining a healthy lifestyle is key to supporting immune function and overall well-being.
