What is the main function of the skeletal system?

• Transport oxygen through the body

• Provide structure and support

• Produce hormones

• Break down food

The muscular system allows for:

• Blood circulation only

• Voluntary and involuntary movement

• Sensory input

• None of the above

The nervous system’s primary function is to:

• Pump blood throughout the body

• Break down food

What is the main function of the heart?

• Digest food

• Filter blood

• Pump oxygenated and deoxygenated blood throughout the body

• Produce white blood cells

Which body system is responsible for gas exchange (oxygen in, carbon dioxide out)?

• Respiratory system

• Lymphatic system

• Digestive system

• Nervous system

The digestive system’s main function is to:

• Transport oxygen

• Break down food and absorb nutrients

• Protect against infections

• Pump blood through the body

The small intestine’s primary role is to:

• Store waste
