Human Body Systems
Integumentary System
Skeletal System
Muscular System
Nervous System
Endocrine System
Urinary System
Digestive System
Respiratory System
Circulatory System
Lymphatic (Immune) System
Reproductive System
Integumentary System
Skin and accessory organs (hair, nails)
Skin
Protects body from injury (1st line of defense)
Maintains body temperature (homeostasis)
Prevents body from drying out
Skeletal System
Provides support and protection
Muscular System 
Responsible for movement
Nervous System
Sends and receives messages
Brain, spinal cord, nerves
Uses electrochemical signals
Monitors environment, allowing us to respond
Endocrine System
Produces and releases hormones
Urinary System 
Removes waste from blood to create liquid waste
Digestive System
Breaks down food to deliver nutrients to cells
Removes solid waste
Respiratory System
Brings oxygen to cells
Rids of CO2
Responds by increasing or decreasing breathing rate to maintain homeostasis
Circulatory System
Pumps blood to all body parts
Transports, regulates (pH, temp, etc.), and protects (immunity/clotting)
Plasma contains nutrients and hormones
Blood is composed of red blood cells, white blood cells, and platelets
Lymphatic (Immune) System
Aids in immunity and returns excess fluid to circulation
Specialized cells protect from foreign substances
Some cancer cells may be created
Reproductive System 
Allows for continuation of the species
Requirements for the Human Body System 
Obtain energy through a food source
Homeostasis
Coordinate bodily functions
Reproduction
