Final answer:
The structure of the stomach in the digestive system is specifically linked to its function. It has a muscular wall lined with rugae and gastric glands that allow it to expand, contact, and secrete enzymes and acids to break down and digest food.
Step-by-step explanation:
An example that illustrates the link between the structure and function of an organ in the digestive system is the stomach. The stomach has a muscular wall lined with folds called rugae, which allow it to expand and contract to accommodate the food consumed. It also has specialized cells called gastric glands that secrete enzymes and acids to break down the food. The structure of the stomach, with its rugae and gastric glands, allows it to efficiently mix and break down the food into smaller molecules for further digestion.
