Verified step by step guidance

Step 1: Begin by understanding the levels of organization in the human body. These levels include: cells, tissues, organs, and organ systems. Each level builds upon the previous one.

Step 2: Recall the definition of a cell. A cell is the basic structural and functional unit of life. It is the smallest level of organization in the human body.

Step 3: Next, understand what a tissue is. A tissue is a group of similar cells that work together to perform a specific function. Examples include muscle tissue and epithelial tissue.

Step 4: Now, consider the definition of an organ. An organ is a structure composed of multiple types of tissues that work together to perform specific functions. For example, the stomach is made up of muscle tissue, epithelial tissue, and connective tissue, all working together to aid in digestion.

Step 5: Finally, recognize that an organ system is a group of organs that work together to perform a broader function. For example, the stomach is part of the digestive system, which includes other organs like the intestines and liver. Since the stomach is a single structure composed of tissues, it is classified as an organ.
