Verified step by step guidance1
Understand the question is asking about a component in the human body that contains beneficial bacteria and helps resist pathogens.
Recall that the human body hosts many microorganisms, especially bacteria, that live on and inside us without causing disease; these are known as the normal microbiota or normal flora.
Recognize that normal microbiota play a crucial role in protecting the body by competing with harmful pathogens for resources and space, thus preventing infections.
Identify that lymphatic fluid, red blood cells, and connective tissue do not contain beneficial bacteria and do not serve this protective function in the same way.
Conclude that the component consisting of beneficial bacteria and helping resist pathogens is the normal microbiota.
