Question

Pathogenic bacteria that succeed in penetrating the wall of the large intestine into the blood circulation are removed or destroyed by

Answer 1

Intestinal Epithelial Cells (IEC)

Step-by-step explanation:

• Polarized intestinal epithelial cells (IEC), as well as the resident microflora, provide a barrier that guards against microbial invasion
• The necessity for the epithelium to maintain an intact barrier between lumen bacteria and the lamina propria is exemplified by the consequences after the barrier function is altered
• Impairment of the barrier function of the intestinal epithelium may be a predominant mechanism in the pathogenesis of inflammatory bowel disease (IBD)
