Verified step by step guidance

Begin by understanding the levels of organization in the human body, which include: chemical, cellular, tissue, organ, organ system, and organismal levels.

Recognize that the cellular level consists of individual cells, which are the basic units of life, but do not perform complex functions as a group.

Identify the tissue level as the organization where similar cells group together to perform specific functions. Tissues are collections of similar cells and their extracellular matrix, working together to carry out particular tasks.

Differentiate the organ level, where tissues combine to form organs, each with specific functions, but not limited to similar cells.

Understand that the organismal level is the complete human body, where all systems work together to maintain life, encompassing all levels of organization.
