What are the advantages of the four chambers of the heart in three and two hearts with partitions partitions?
Birds and mammals four chambers of heart left and right are defined separately. Structurally, the heart of reptiles and amphibians are different. Amphibians have two hearts cameras all reptiles have three hearts chambers with a partial divider. What are the advantages of the structure of the heart in comparison those of mammals, reptiles and amphibians? Thank you. 
4 cores cameras allow a system of dual circulation, which means that two inner loops: one for the lungs and body. This means that you may have a higher blood pressure in "loop" is in the body (high blood pressure can damage the lungs), This means that more oxygen can be delivered to the body, allowing more complex processes.
