The circulatory system is integral with the cardiovascular system. Pick an animal and detail how that animals heart and lungs interact with each other as that animal breathes. Are there additional structures involved with respiration in that animal? If so, describe them.
The heart is key for circulating and removing wastes. The external environment of an animal can have an effect on how the heart functions. Pick an animal and create a 1 page Fact Sheet on how environmental temperature may affect circulation of that specific animal. This may include effects to the body, effects directly on heart-rate, or changes in heart shape, function, or size. Be sure to answer the question: Are these changes associated with changes in the animals metabolic rate as environmental temperatures change?
