Organs combine to form organ systems.
Organ systems are groups of organs that work together to perform a specific function within an organism. This collaborative effort is crucial for the overall health and survival of the organism. For example, the digestive system is made up of organs like the stomach, intestines, liver, and pancreas, all working in concert to process food and extract nutrients.
Here's a breakdown:
- Cells: The basic building blocks of life.
- Tissues: Groups of similar cells working together.
- Organs: Collections of different tissues performing a specific function.
- Organ Systems: Groups of organs working together to perform complex tasks. The function of an organ system depends on the integrated activity of its organs. This means that each organ's contribution is essential for the system's overall function.
Examples of organ systems include:
- Digestive System: Breaks down food for absorption of nutrients.
- Respiratory System: Facilitates gas exchange (oxygen and carbon dioxide).
- Circulatory System: Transports blood, oxygen, and nutrients throughout the body.
- Nervous System: Controls and coordinates bodily functions.
The integrated function highlighted in the reference emphasizes the importance of the coordinated activities of individual organs within an organ system. No single organ can perform the system's function in isolation; they must work together.
