The heart is also divided: each circulatory system has an atrium and a ventricle, with the left and right halves of the heart differing in form and function. 1.Heart is situated in the thoracic cavity, between the lungs of two sides (Mediastinum). The difference between the circulatory system of birds… The two auricles are completely separated by inter auricular sep­tum. So blood circulation is of closed type in verte­brates. Mammals and birds are the most evolved groups of animals with a great variety among them. Within a human, circulation forms a loop from the heart throughout the different sections of the body. This is called heart beat. Human, fish and reptile heart 1. 0 0. Birds have proportionately larger hearts compared to mammals. Both these groups have special ecological niches.
