Etymology
Origin of intestine
First recorded in 1525–35; from Latin intestīnum, noun use of neuter of intestīnus “internal,” equivalent to intes- (variant of intus “inside”) + -tīnus adjective suffix; cf. vespertine
Explanation
When you eat food, it first passes into your stomach, and then into your intestine. Fun fact: your large intestine is about five feet long. Makes you wonder why they don't call it your "long intestine" instead. The human intestine is split into two sections: the small intestine and the large intestine. Your intestine's job is to continue breaking down the food you've eaten and absorb nutrients into your bloodstream. Intestine comes from the Latin word intestinum, "gut" or "bowels," which is the neuter form of the adjective intestinus, "inward" or "internal."
