Explanation:

Double communication system

Double circulation pathways are found in birds and mammals. Animals with this type of circulatory system have a four-orbital heart.

The right atrium is deoxygenated from the body and the right ventricle sends it to the lungs in the form of oxygen. The left atrium receives oxygen-rich blood from the lungs and the left ventricle sends it to the rest of the body. Most mammals, including humans, have this type of circulatory system. These communication systems are called 'double' communication systems because they are made up of two circuits, called pulmonary and systemic communication systems.
