Final answer:
The levels of structural organization of body systems range from the cellular to the organizational level, progressing from individual cells to tissues, organs, and organ systems.
Step-by-step explanation:
The levels of structural organization of body systems from the cellular to the organizational level are as follows:
- Cellular level: This is the level where basic functions are carried out by individual cells, such as metabolism, reproduction, and response to stimuli.
- Tissue level: It involves the organization of similar cells that work together to perform a specific function, like epithelial tissue that lines the organs.
- Organ level: Organs are made up of different tissues working together, and they perform specific tasks in the body, such as the heart or the liver.
- System level: Organ systems consist of multiple organs that work together to perform a common function. For example, the respiratory system comprises organs like the lungs, trachea, and bronchi that work together to facilitate gas exchange.
