innate immunity is the non-specific defence we're born with; acquired immunity is specific and develops after exposure.
I keep getting “Innate vs acquired immunity” questions wrong in Human Health & Disease. What's the trap?
thinking all immunity is present from birth.
What does “Active vs passive immunity” actually mean in Human Health & Disease, and why does it matter for NEET?
active immunity is when the body makes its own antibodies; passive immunity is receiving ready-made ones.
I keep getting “Active vs passive immunity” questions wrong in Human Health & Disease. What's the trap?
calling a vaccine passive immunity.
What does “Antibodies” actually mean in Human Health & Disease, and why does it matter for NEET?

What is the difference between innate immunity and acquired immunity?
Innate immunity is fast and non-specific (skin, phagocytes); acquired immunity is slower, specific, and has memory (antibodies).
What is the difference between active immunity and passive immunity?
Active immunity is made by your own body (vaccine, infection) and lasts long; passive immunity is borrowed antibodies (mother's milk, antivenom) and is short-lived.
What is the difference between antigen and antibody?
An antigen is a foreign molecule that triggers a response; an antibody is the protein the body makes to bind and neutralise it.
How is Human Health & Disease tested in NEET, and what should I focus on?
Prioritise the core ideas: Innate vs acquired immunity, Active vs passive immunity, Antibodies.
What are the most common mistakes students make in Human Health & Disease?
antibiotics act only on bacteria; they are useless against viruses like the common cold, and overuse causes resistance.
How do I revise Human Health & Disease quickly before the exam?
One-page summary of Innate vs acquired immunity, Active vs passive immunity, Antibodies, then timed previous-year questions.
