Infectious agents do NOT travel to their target tissue through Blank______.Multiple choice question.the bloodstreamnervesmusclescerebrospinal fluid

To determine which option does not serve as a pathway for infectious agents to travel to their target tissue, let's analyze each choice:

1. The Bloodstream: Infectious agents, such as bacteria and viruses, can enter the bloodstream and travel throughout the body, reaching various tissues and organs. Therefore, this option is incorrect.

2. Nerves: Some pathogens can spread along nerve pathways. For instance, viruses like rabies can follow nerve fibers to reach the central nervous system. Thus, this option is also incorrect.

3. Muscles: While infectious agents can infect muscle tissue, they do not typically travel through muscle as a means of spreading to other tissues. This option is a potential candidate for the correct answer, as muscle itself does not serve as a direct pathway.

4. Cerebrospinal Fluid: Certain infectious agents can access the cerebrospinal fluid, allowing them to reach the central nervous system. Therefore, this option is incorrect.

Final Answer

The correct answer is muscles; infectious agents do NOT typically travel to their target tissue through muscles.
