Study Notes

Organ Systems in the Human Body

The human body contains several organ systems that work together to maintain life
These systems allow growth, obtain energy, move, stay healthy, and reproduce

Body Systems

Skeletal System: Provides support, protects internal organs, enables movement, stores minerals, produces blood cells
Integumentary System: Protects against infections and injuries, regulates body temperature
Muscular System: Enables movement through skeletal, smooth, and cardiac muscles
Circulatory System: Transports oxygen, nutrients, and wastes; fights infection, regulates temperature
Respiratory System: Supplies the body with oxygen, removes carbon dioxide
Digestive System: Breaks down food, absorbs nutrients, removes wastes

Defense System

Immune System: Defends against infections through lymph nodes, lymph vessels, and white blood cells
The immune system works with other organs to fight off diseases and invading organisms
