ANATOMY

Detailed explanation-1: -Most are helpful or at least harmless. The three or so pounds of bacteria living in our gut-mostly in the large intestine-help us digest all manner of food. It’s these tiny stowaways that interest Andrzej Joachimiak and his team the most, in part because they can have a tremendous impact on human health.

Detailed explanation-2: -Your large intestine is not just made up of cells. It is also an ecosystem, home to trillions of bacteria known as the “gut flora” (Figure below). But don’t worry, most of these bacteria are helpful. Friendly bacteria live mostly in the large intestine and part of the small intestine.

Detailed explanation-3: -However, gut bacteria can be potentially harmful when the gut ecosystem undergoes abnormal changes. Dysbiosis of the gut bacteria communities in patients or animal models may cause allergy, inflammatory bowel disease (IBD), obesity, diabetes, and even cancer [8, 9].
