Four Chambers of heart.Double circulation(pulmonary and systemic)
Need of double circulation.Trace the path of blood from lungs-->pulmonary vein -->Left Atrium-->Left Ventricle-->Aorta-->Body parts(oxygenated blood).
Cells-->Right Atrium-->Right Ventricle-->pulmonary artory-->Lungs(Deoxygenated blood). pulmonary circulation starts from Right Ventricle and ends in Left Atrium.systemic circulation starts from Left Ventricle and ends in Right Atrium. Represent schematically and study.
