Final answer:
The digestive system is an example of how the human body's multiple subsystems interact to perform a specific function.
Step-by-step explanation:
One example of how the human body's multiple subsystems interact to perform a specific function is during the process of digestion. The digestive system, which includes organs such as the stomach, liver, and intestines, works together with other systems like the circulatory and nervous systems to break down food and absorb nutrients.
For instance, when we eat, the mouth chews food and begins the digestion process by breaking it down into smaller pieces. The food then travels down the esophagus through muscle contractions and enters the stomach, where it is further broken down by stomach acids. The small intestine, liver, and pancreas assist in breaking down nutrients and absorbing them into the bloodstream.
This example demonstrates how the digestive system interacts with the circulatory system, as nutrients from digested food are transported through the blood vessels. It also involves the nervous system, which helps control the process by sending signals to different organs.
