Organ and Organ System Concept
How tissues combine into organs and coordinated systems. (Biology › Structural Organisation in Animals, NEET UG syllabus.)
What is Organ and Organ System Concept?
A collection of different types of tissues that are organized to perform a specific function.
Key points
- Define an organ and provide examples.
- Define an organ system and provide examples.
- Explain the hierarchical organization from tissues to organ systems.
- Describe the primary functions of major organ systems.
Common exam trap
Confusing the definition of an organ with a tissue or a cell.
