What is the function of a body system in the human body?

1. Maintaining body temperature within a narrow range.

2. Assisting with regular bowel movements.

3. Facilitating breathing by expelling air from the lungs.

4. Performing specific functions via groups of organs.

The correct answer is: Performing specific functions via groups of organs.

The function of a body system in the human body is to perform specific functions via groups of organs. This means that each body system, such as the digestive system, circulatory system, or respiratory system, is made up of various organs that work together to carry out a set of specialized functions necessary for maintaining the overall health and stability of the body. For example, the digestive system includes organs like the stomach and intestines that collaboratively process food, extract nutrients, and eliminate waste. While the other choices describe important physiological processes, they are specific actions rather than the broader definition of a body system's function. Maintaining body temperature, assisting with bowel movements, and facilitating breathing are all crucial functions, but they are outcomes of the integrated efforts of multiple organs and systems rather than a comprehensive description of what defines a body system. By focusing on the collaborative nature of organs within a system, we can appreciate how interrelated and specialized the human body's structures are in promoting overall well-being.
