Question

a person gets a splinter in their finger, which introduces bacteria into their 1 point tissues. which of the following best describes the likely sequence of immune responses that follows? the adaptive immune system recognizes the bacteria from a previous splinter and mounts a memory response. leukocytes of the innate system engage in a rapid, non - specific phagocytosis response, which is later supported by a specific, slower adaptive response if the infection persists. the lymphatic system immediately filters the bacteria out of the finger tissue before any cellular response is needed. b cells immediately produce antibodies specific to the bacteria, resolving the infection within minutes.

Explanation:

The innate immune system is the first - line defense and acts rapidly in a non - specific way. Leukocytes in the innate system, like macrophages, can phagocytose bacteria. If the infection persists, the adaptive immune system, which is more specific, will be activated. Memory responses in the adaptive system are triggered by repeated exposure to the same pathogen and are not the first response. The lymphatic system does not immediately filter out bacteria before any cellular response, and B - cell antibody production is part of the adaptive response which is slower and not immediate for a first - time exposure.

Answer:

Leukocytes of the innate system engage in a rapid, non - specific phagocytosis response, which is later supported by a specific, slower adaptive response if the infection persists.
