To the 78 organs that make up the human body, we can add one more: the mesentery.
Located in our abdominal cavity, the mesentery is a belt of tissue that holds our intestines in place. While anatomists knew it was there, it was always thought to be composed of several different segments, as opposed to being one single structure. This knocked it out of contention for organ status, as our bodily organs must be continuous, as well as provide some vital function to our anatomy.
