Question

Quizplus · Accepted Answer

Tight junctions play an important role in maintaining the integrity of the intestinal wall and preventing the movement of microorganisms from the intestine into the bloodstream. If the tight junctions are disrupted, it could lead to the movement of bacteria into the bloodstream causing an infection. This is because the tight junctions act as a physical barrier between the intestinal lumen and the bloodstream. disruption may lead the bacteria to cross that barrier. A, B, C, and D do not accurately describe the effects of disrupted tight junctions in the intestine.
