The levels of structural organization of the human body are as follows:

1. Chemical level: This is the simplest level of organization, where atoms combine to form molecules such as proteins, carbohydrates, and lipids.

2. Cellular level: At this level, cells are the basic structural and functional units of the body. Cells perform specific functions and are the building blocks of tissues and organs.

3. Tissue level: Tissues are groups of similar cells that work together to perform a specific function. There are four main types of tissues in the body: epithelial, connective, muscle, and nervous tissue.

4. Organ level: Organs are structures composed of two or more different types of tissues that work together to perform a specific function. Examples of organs include the heart, lungs, and liver.

5. Organ system level: Organ systems are groups of organs that work together to perform a specific function. There are 11 major organ systems in the human body, including the cardiovascular, respiratory, digestive, and nervous systems.

6. Organismal level: This is the highest level of organization, where all the organ systems work together to maintain the life of the organism. The human body is a complex organism that requires coordination between all levels of organization to function properly.
