Working of heart in birds and mammals -

In birds and mammals, oxygenated and deoxygenated blood received by the left and right atria respectively passes on to the ventricles of the same sides. The ventricles pump it out without any mixing up, i.e., two separate circulatory pathways are present in these organisms

- wherein

This is called double circulation

 

 The labelled parts 1 and 4 are aorta and left ventricle respectively, which carry oxygenated blood. Left ventricle receives oxygenated blood from the left auricle which received it from pulmonary veins and this oxygenated blood then moves into the aorta to be supplied to the whole body.
