The document discusses the concept of double circulation, where blood flows through the heart twice in one cycle. It describes double circulation as consisting of pulmonary circulation, where deoxygenated blood flows from the heart to the lungs to become oxygenated, and systemic circulation, where oxygenated blood flows from the heart to the rest of the body and becomes deoxygenated before returning to the heart. The document is a PowerPoint presentation about double circulation presented by Sangeetha K.P.
