Q. Which part of the human body can expand several times its size under excitement?

Answer: Stomach

The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the oesophagus. As food reaches the end of the oesophagus, it enters the stomach through a muscular valve called the lower oesophagal sphincter. The stomach secretes acid and enzymes that digest food.
