Circulatory Systems. Below you will find a large list of organisms. Follow the directions for each section.

Section 1. Put a * by every animal that has a closed circulatory system.

Section 2. Place an S next to the organisms that have a single circulatory system at the adult stage. Place a P next to organisms that have a pulmocutaneous circulatory system at the adult stage. Place a D next to organisms that have a double circulatory system at the adult stage. Some organisms may not have a D, P, S and some may have more than one letter for this section.

Section 3.Next, place an L next to the organisms that have a pulmonary circuit (why did we choose for you to use the letter L?).
