what contributes to the prevention of bacteria crossing the mucosal barrier?
saccharolytic fermentation
haustral contractions
dendritic cells
mass movements
save & continue

Explanation:

Dendritic cells are part of the immune system. They play a crucial role in sampling antigens (including potential pathogens like bacteria) from the mucosal surfaces. By doing so, they can initiate immune responses if bacteria or other harmful agents are detected, thus helping prevent bacteria from crossing the mucosal barrier. Saccharolytic fermentation is related to the breakdown of sugars (not directly barrier - prevention). Haustral contractions are a type of intestinal movement for mixing contents. Mass movements are large - scale intestinal movements for propulsion.

Answer:

C. Dendritic cells
