Digestion is a form of catabolism or breaking down of substances that involves two separate processes:
mechanical digestion and chemical digestion
. Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion.
Where is the stomach in the human body?
The stomach is a muscular organ located
on the left side of the upper abdomen
. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter.

Where is bowel located?
It is
between the stomach and the large bowel (colon)
. The small bowel is between 4 and 6 metres long. It folds many times to fit inside the tummy (abdomen). It breaks down food, allowing vitamins, minerals and nutrients to be absorbed into the body.
What is it called when your stomach is empty and wrinkles?

How long is the gut?
Research suggests that the combined length of the
small and large intestines is at least 15 ft in length
. The small intestine can measure about 9–16 ft, while the large intestine is roughly 5 ft long. The intestines have the important role of helping break down and absorb nutrients from food and drink.
