Passive leakage of partially digested material from the small intestine into the human abdominal cavity may result from defects in which of the following type of intercellular junction?
A) desmosomes
B) gap junctions
C) plasmodesmata
D) tight junctions

Question

Quizplus · Accepted Answer

Tight junctions are specialized structures in cell membranes that create a watertight seal between adjacent cells, preventing the leakage of materials between cells. In the context of the small intestine, they prevent the leakage of partially digested material into the abdominal cavity. Defects in tight junctions can lead to such leakage, highlighting their critical role in maintaining the integrity of barriers within the body.
