Immune System starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Immune System.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12

Fill in the blank: The process by which a vaccine stimulates the immune system to develop protection against a disease is called _______.
True or False: Antibodies can directly kill pathogens.
True or False: Autoimmune diseases occur when the immune system attacks the body’s own tissues.
