Protects from pathogens gaining easy access to our bodies as well as trauma

Helps regulate our body temperature

Hairs help with perceiving sensory input, warmth, and signalling maturity

Prevents excess water absorption or loss

Protects from UV rays

Acts as the body's frame and gives it a defining shape

Attaches to muscles which then allow for movement

Stores minerals, especially calcium

Provides protection for internal organs

Blood cells are formed in bone marrow

Muscles are the driving force for movement

Many muscles actually work to prevent movement so that our bodies do not slump or fall over

Openings in the body such as our eyes and mouth are controlled by muscles

Muscles are vital in generating body heat

When muscles have been worked, they excrete hormones that stimulate glucose synthesis and burn body fat

The system works to regulate blood glucose level by storing and using glucose

Sensory neurons are responsible for detecting information and transmitting it to the central nervous system to be interpreted

Once information is interpreted, a response is then sent back through the nervous system depending on the what the stimulus was

Sends signals to muscles, telling them to act

Our eyes are responsible for giving us sight

Ears allows us to hear and stay balanced

All over our body we can feel sensation, but primarily in the hands and feet are where touch is most defined

Our nose detects smells that can make us feel good or detect danger

Our tongue is responsible for our sense of taste, which lets us know when something is good or bad for us
