Organs in the body tend to be in a set order and position. This is useful when it comes to diagnosing certain conditions. Anyone with appendicitis or gallstones, for example, will tell you exactly where the agonising pain is. Sometimes, though, organs end up in the “wrong” place.
Developmentally, one of the largest single organ abnormalities is dextrocardia where the heart, instead of being slightly over to the left (known as levocardia), is flipped to the right. This is a fairly rare occurrence, about one in 12,000 people are born this way.
