Verified step by step guidance

Begin by understanding the hierarchy of biological organization in the human body, which starts from cells, then tissues, organs, organ systems, and finally the organism.

Recognize that tissues are groups of similar cells that work together to perform a specific function. For example, muscle tissue is composed of muscle cells that contract to produce movement.

Identify that organs are structures composed of multiple types of tissues that work together to perform complex functions. For instance, the heart is an organ that includes muscle tissue, connective tissue, and nerve tissue, all contributing to its function of pumping blood.

Clarify that organs are not the smallest unit of life; cells are the smallest unit of life. Tissues are composed of cells, and organs are composed of tissues.

Conclude that the correct relationship is that organs are composed of tissues that work together to perform specific functions, distinguishing the levels of organization between tissues and organs.
