Question

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

Explanation:

To solve this, we recall the definitions of innate and adaptive immune responses:

• Innate Immune Response: Nonspecific, immediate, and present from birth (e.g., inflammation, fever, transplant rejection as it targets foreign tissue generally).
• Adaptive Immune Response: Specific, develops over time, targets specific pathogens (e.g., vaccine-induced immunity, as vaccines train the immune system to recognize specific antigens).

Innate Immune Response (nonspecific, immediate):

• A transplanted liver is rejected by the recipient: Transplant rejection involves innate mechanisms (e.g., natural killer cells) and early inflammatory responses.
• Swelling occurs around the area of a scratch: Inflammation (swelling) is a classic innate response to injury/pathogens.
• A person has a high fever during a viral infection: Fever is an innate defense to inhibit pathogen growth.

Adaptive Immune Response (specific, acquired):

• A person injected with the typhoid vaccine becomes immune to typhoid fever: Vaccines induce adaptive immunity by training B and T cells to recognize typhoid antigens.

Answer:

Innate Immune Response:

• A transplanted liver is rejected by the recipient.
• 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.
