Essential Questions Why do animals need a circulatory system?
How are various substances transported and exchanged in the human
body? What are heart rate, blood pressure, and breathing rate, and
how are they affected by exercise? How do we obtain energy from the
food we ingest? What are the different components of the
circulatory system and what are their functions? What are different
