Expert
The bird and the mammalian hearts are divided into four chambers:
a) Right atrium, b) Right ventricle, c) Left atrium and d) Left ventricle.
Birds and mammals are homoeothermic, that is, they control the temperature of the body. The four-chambered heart and double circulation offers more supply of oxygenated blood to the tissues resulting in the higher metabolic rate majorly cellular respiration rate. Part of the energy generated by the cellular respiration is used to manage the body temperature.
