Circulatory System

• Function
• brings oxygen, nutrients, and hormones to cells,
  fights infection, removes waste, regulates body
  temp.
• The system that transports!!!

• Invertebrate Organs simple heart, vessels
• Vertebrate Organs
• Heart, blood vessels (veins, arteries and
  capillaries) and blood

Where is your blood made? Hint Its made in
a different system.
3
Animal circulation

• Circulation systems are the systems used to
  transport oxygen throughout the body to the cells
  so they can perform the essential process of
  cellular respiration.

Why does you heart pump blood? BE
SPECIFIC Hint the answer is not TO LIVE
