Final answer:
The intestines use a dense suite of tight junctions to prevent microbes from entering the underlying tissue, maintaining a waterproof barrier essential for protecting the body from pathogens. Hence, option (c) is correct.
Step-by-step explanation:
Of the options listed, it is the intestines that use a particularly dense suite of tight junctions to prevent microbes from entering the underlying tissue.
Tight junctions are essential in maintaining the barrier function of epithelial tissue, which lines internal organs and cavities as well. These tight junctions create a waterproof barrier that regulates the passage of substances and prevents the leakage of bacteria and other pathogens into the body's tissues.
In the intestines, specifically, tight junctions play a critical role in the epithelial lining by preventing undesired substances and microbes present in the gut lumen from infiltrating the underlying tissue.
