12. Respiratory SystemCirculatory System

13. Respiratory System  Inhaled air passes into air sacs  When a bird exhales, air passes from air sacs to lungs  Air enters lungs when both inhaling and exhaling Circulatory System  Heart is large compared to body  Heart beats rapidly  Blood carrying oxygen is kept separate from blood carrying carbon dioxide

14.  A bird’s adaptation to his environment and his food is shown most obviously in his beak and feet. Describe and explain these two previous adaptations that are most commonly seen in one of the following birds.  (you may draw these parts to help in your explanation, but don’t forget to explain their use)
