Double Circulatory System

• The mammals have a double circulatory system.
  Blood passes through the heart twice before being
  pumped to the tissues of the body. The
  circulatory system can be divided into two
• Pulmonary (including the heart and lungs).
• Systemic (including the heart and the rest of
  body).
• This means the heart has 2 sides!
