What is the main function of the circulatory system?

• Transports blood to all parts of the body

• To provide gas exchange between blood and the air

• To break down food in to nutrients that can be used by the body

• To filter cellular wastes, toxins and excess water

• To receive and interpret stimuli from inside and outside the body

What is the main function of the nervous system?

• To provide gas exchange between the blood and air

• Transports blood in the body

• To provide movement and support for the body

• To receive and interpret stimuli from inside and outside the body

• To filter wastes, toxins and excess water
