Why appendix is called blind ended?

The appendix is referred to as "blind-ended" because it is a tubular structure that has one open end connecting to the large intestine and an closed end, meaning it does not have a continuous passage leading to another organ or cavity. This structure limits its function in the digestive system, making it a vestigial organ in humans. Its blind-ended nature also means it can become easily obstructed, leading to conditions such as appendicitis.
