Verified step by step guidance

Understand the levels of organization in the human body: The human body is organized into several levels, starting from the smallest unit, the cell, and building up to the entire organism.

Identify the cellular level: This is the most basic level, consisting of cells, which are the smallest living units in the body.

Recognize the tissue level: Tissues are groups of similar cells that work together to perform a specific function. Examples include muscle tissue and nervous tissue.

Define the organ level: An organ is a structure composed of at least two different types of tissues that work together to perform a specific function. Examples include the heart, lungs, and stomach.

Differentiate the organ system level: This level consists of groups of organs that work together to perform complex functions necessary for survival, such as the digestive system or the circulatory system.
