Question

classify the responses in the given situations as part of innate immune response or adaptive immune response.
innate immune response
adaptive immune response
a transplanted liver is rejected by the recipient.
a person injected with the typhoid vaccine becomes immune to typhoid fever.
swelling occurs around the area of a scratch.
a person has a high fever during a viral infection.

Explanation:

Innate immune response is non - specific and immediate, while adaptive is specific and takes time to develop. Swelling around a scratch is part of innate immune response as it is a general defense mechanism. A high fever during viral infection is also innate as it is a non - specific response to infection. Adaptive immune response occurs when the body is exposed to a specific antigen like in vaccination (a person injected with typhoid vaccine becomes immune) or in organ transplantation rejection (a transplanted liver is rejected by the recipient).

Answer:

Innate Immune Response: Swelling occurs around the area of a scratch., A person has a high fever during a viral infection.
Adaptive Immune Response: A person injected with the typhoid vaccine becomes immune to typhoid fever., A transplanted liver is rejected by the recipient.
