- Components: Comprises multiple organs (e.g., heart, lungs, liver) that have distinct functions yet work in harmony.
- Functionality: Each system has a unique role; for instance, the circulatory system transports blood, while the digestive system processes food.
- Examples of Organ Systems:
- Circulatory System: Heart, blood vessels, and blood.
- Digestive System: Stomach, intestines, liver, and pancreas.
- Respiratory System: Lungs, trachea, and diaphragm.
- Nervous System: Brain, spinal cord, and nerves.
Importance:
Organ systems are essential for sustaining life by ensuring that the body can efficiently perform necessary functions like circulation, digestion, respiration, and regulation. Proper functioning of one system often impacts others, demonstrating the interconnectedness of bodily functions.
