Question

Differentiate between non-specific and specific immunity.

Answer 1

Aspect	Non-specific immunity	Specific immunity
Nature	It is present from the time of birth and is hereditary.	It is acquired or learned during an individual’s lifetime.
Specificity	It provides a broad defense against all types of pathogens.	It is highly specific to a particular pathogen (like a virus or bacteria).
Memory	It does not have any immunological memory of past infections.	It possesses memory, allowing for a faster response upon re-exposure.
Components	It consists of barriers like skin, stomach acid, and tears.	It is mediated by specialized cells called B-lymphocytes and T-lymphocytes.
Response speed	The immune response is immediate and acts as the first line of defense.	The initial response is slower, but the subsequent response is much faster.
