What is a double circulatory system?
When there are two routes for blood to take--from the heart to the lungs and back, and from the heart to the body and back.
1 of 6
Why do mammals have double circulatory systems?
They are more efficient; they require more energy due to their high activities; they have to maintain a 37°C body temperature
2 of 6
What is an open circulatory system?
When the blood is in direct contact with body cells (insects)
3 of 6
What is a closed circulatory system?
The blood is always within blood vessels (mammals)
4 of 6
What is a single circulatory system?
Found in fish--blood can only go from the tissues to the heart to the gills and back to the tissues.
5 of 6
Why are fish suited to a single circulatory system?
They don't need to maintain a body temperature and they don't need much energy because they don't do anything.
