KEY: How Do All the Systems Work Together Skeletal System Muscular System Digestive System Respiratory System Circulatory System Urinary System Nervous System • Gives skeletal • Protects the • Protects trachea, • Protects heart • Protects the • Protects the brain muscle something mouth, vocal cords and • Bone marrow kidneys and spinal cord Skeletal to pull against to esophagus, diaphragm produces red System skeletal muscle stomach, liver, blood cells can move pancreas, and • Gives support to gall bladder the body

• Skeletal muscles • Smooth muscle- • Smooth muscle- • Cardiac muscle- • Smooth muscle- • Provides move bone found in the the diaphragm heart bladder protection for Muscular • Tendons connect esophagus, • Smooth muscle impulses sent System muscle to bone stomach, small located in veins down through the and large and arteries body from the intestines, and brain rectum

• Provides nutrients • Provides nutrients • Provides the • Provides the • Provides • Provides energy for bone growth for muscles to do diaphragm heart with nutrients so the for the brain to all Digestive and repair work-whether it is nutrients in order nutrients so the kidneys can clean the thinking and System skeletal, smooth facilitate heart can keep your blood of controlling of all or cardiac muscle breathing beating wastes produced the other systems • Half of the by all the other equation for systems respiration Glucose + Oxygen = water, carbon dioxide and energy

Skeletal System Muscular System Digestive System Respiratory System Circulatory System Urinary System Nervous System • Provides oxygen • Provides oxygen • Provides oxygen so • Provides the • Provides oxygen • Provides oxygen so bones can go so muscles the digestive system oxygen that is so the urinary so the brain to can digest your food and do work (skeletal, smooth carried by red system can clean think and control • Removes carbon Respiratory • Removes carbon and cardiac) can dioxide and water the blood cells to all the blood of all the other System dioxide and water go and do work cells produce as a the parts of the waste products systems of the that skeleton cells • Removes carbon waste product body • Removes carbon body produce as a dioxide and water • Is the other half of the • Removes carbon dioxide and • Removes carbon waste product that muscle cells energy formula dioxide and water that the dioxide and • Glucose + Oxygen = produce as a water, carbon dioxide water that heart urinary systems water that the waste product and energy cells produce as produces as a brain cells a waste product waste product produce as waste products • Moves oxygen and • Moves oxygen and • Moves oxygen and • Moves oxygen and • Moves oxygen and • Moves oxygen and glucose around glucose around glucose around glucose around glucose around glucose around the body so cells the body so cells the body so cells the body so cells the body so cells the body so cells Circulatory can do work can do work can do work can do work can do work can do work System • Moves wastes so • Moves wastes so • Moves wastes so • Moves wastes so • Moves wastes so • Moves wastes so they can be they can be they can be they can be they can be they can be disposed by the disposed by the disposed by the disposed by the disposed by the disposed by the body body body body body body
