Organ Level: Which statement is correct?

• A. They are made up of only one tissue type.
• B. They are made up of different types of tissues.
• C. They are the smallest units of life.
• D. They perform only one function.

Answer: (B)

At the organ level, structures are built from several tissue types working together to carry out the organ’s functions. An organ like the stomach shows this mix: smooth muscle tissue churns contents, epithelial tissue lines and protects while also helping with secretion, connective tissue provides support, and nervous tissue helps regulate activity. This combination allows the organ to perform its roles effectively. If an organ were made of only one tissue type, it wouldn’t have the versatility needed for its duties. The smallest units of life are cells, not organs, so organs aren’t described as the tiniest living units. And organs usually perform more than one function within the body’s system, not just a single task.
