Define Body Systems -:
Body systems are groups of organs and tissues that work together to perform specific functions essential for survival. These systems maintain homeostasis by coordinating activities like nutrient transport, waste removal, and response to the environment. [1][2]
● Major Systems
The human body typically includes 11 main organ systems, though some classifications combine the skeletal and muscular into one musculoskeletal system. [1][3]
● Each system has distinct roles :-
- **Integumentary**: Protects against injury and regulates temperature via skin, hair, and nails. [1][3]
- **Skeletal**: Provides structure, support, and blood cell production through bones and cartilage. [1][3]
- **Muscular**: Enables movement, posture, and heat generation with skeletal, smooth, and cardiac muscles. [1][3]
- **Nervous**: Detects stimuli and coordinates responses using the brain, spinal cord, and nerves. [1][3]
● Key Functions
Systems interconnect; for example, the cardiovascular system transports oxygen from the respiratory system while the digestive system breaks down food for nutrient absorption. [1][5] The lymphatic system supports immunity by filtering fluids and producing white blood cells. [3][4]
● Full List Overview
| System | Primary Function | Key Components |
|--------|------------------|---------------|
| Cardiovascular | Transports blood, oxygen, and nutrients | Heart, blood vessels [1] |
| Respiratory | Gas exchange (oxygen in, CO2 out) | Lungs, airways [1] |
| Digestive | Nutrient breakdown and absorption | Stomach, intestines [1] |
| Urinary | Waste filtration and fluid balance | Kidneys, bladder [1] |
| Endocrine | Hormone regulation | Glands like thyroid [1] |
| Reproductive | Reproduction and sex characteristics | Ovaries, testes [3] |
