Which statement best describes the relationship between tissues and organ systems?

• A. An organ system includes tissues
• B. A tissue includes organs
• C. An organ system contains cells only
• D. A tissue is larger than an organ system

Answer: (A)

Hierarchical organization from tissues to organ systems. A tissue is a group of similar cells working together. An organ is made up of different tissues that cooperate to carry out a specific function. An organ system is a set of organs that coordinate to perform broader bodily processes. Therefore, an organ system includes tissues because the tissues are inside the organs that belong to the system. The idea that a tissue includes organs would be backwards, thinking a system is only cells misses the organ level, and saying a tissue is larger than an organ system contradicts the usual scale. So the best description is that an organ system includes tissues.
