Immunity is your body's ability to destroy pathogens that is previously encountered before the pathogens are able to cause disease, white blood cells, your body's general response to injury, the ability to produce red blood cells

, and the ability to recognize and remove damaged or abnormal cells. Immunity is crucial for protecting your body from infections and diseases, and it plays a key role in maintaining overall health and wellbeing. There are two types of immunity: innate immunity, which is present from birth, and adaptive immunity, which develops as you encounter different pathogens throughout your life. It is important to maintain a healthy immune system through regular exercise, a balanced diet, adequate sleep, and good hygiene practices.
