Cardiorespiratory System

The functions of the respiratory system is to:

• Breathe in air from the environment

• Transfer O² into the blood

• Remove CO² from the blood

• Return air back to the environment

• Create speach

The main functions of the cardiovascular system is to:

• Transport nutrients, gases and waste products around the body

• To protect the body from infection and blood loss

• To help the body maintain a constant body temperature (Thermoregulation)

• To help maintain fluid balance within the body

• To transfer O² into the blood
