Mondo Knows Facts
Most of the immune tissue sits along the gut
An estimated seventy percent of immune cells are stationed in the digestive lining The gut lining faces more foreign material than any other body surface, so it holds a large share of the immune system. Patches of lymphoid tissue in the small intestine and colon sample gut contents constantly. They must tolerate food and resident microbes while still reacting to pathogens. It sits in Mondo's human body collection, one of 200 facts that each trace back to the reference below.
