What term refers to a group of organs that perform closely related functions?

• A. Organ system
• B. Organ
• C. Tissue
• D. Cell

Answer: (A)

Think of organ systems as teams of organs that work together to perform related tasks. An organ is a single structure with a specialized job, like the heart. When several organs coordinate to carry out a broader function—such as digestion, circulation, or defense—that collection forms an organ system. For example, the digestive system includes the mouth, esophagus, stomach, intestines, liver, and pancreas, all partnering to break down food, absorb nutrients, and eliminate waste. This coordination maintains the body's internal balance. Tissues are groups of similar cells, cells are the basic units of life, and organs are the individual structures; an organ system is the group of organs working together to perform related functions.
