Describe the differences between the structure of the circulatory system of a fish and the human circulatory system. 4 marks

In mammals (like us) there is a double circulation. The right side of the heart receives blood returning back from the body; this blood is low in oxygen (blue in the figure to the right). ... In fish, the heart only has one atrium and one ventricle.
