1. Where is the frog’s heart compared to its lungs? How do the locations of these two organs affect interactions between the frog’s respiratory and circulatory systems? The frog’s heart is in front and above the liver while the lungs are under the liver and off to the sides. The locations of these two organs affect interactions between the frogs’s respiratory and circulatory systems because a frog's heart needs oxygen which is required from the lungs therefore the circulatory system which is the blood and the heart needs oxygen from the respiratory system which is the lungs. Since they are so close together, both systems have easy access to one another.
2. Describe how the frog’s circulatory and digestive systems are physically connected. The frogs circulatory and digestive systems are physically connected because t
...he frog’s digestive system includes its liver and this has a hepatic portal system through which veins pass and come out and that is the circulatory system so they are connected. Also they connect at the alveoli.
3. Explain why the interaction of the respiratory and circulatory systems are necessary for the frogs survival. The interaction of the respiratory and circulatory systems are necessary for the frogs survival because the frog’s blood cells pick up and carry oxygen from the lungs of the frog to the body’s cells.
4. Cold blooded animals, such as frogs, are able to deliver blood to their cells once their bodies warm up. Predict when you think frogs are likely to be most active. Frogs are predicted to be most active in warm climates because blood functions slowdown in cold environments.

justify">This is true because you can freeze a frog for many years and then defrost them back to life. Also that is why frogs in warmer areas are more active than frogs in colder areas such as the wood frogs. Wood frogs cannot move during the cold weather because their body freezes down and so the frogs in the warmer areas can be active all year round.
