Types of Circulation in the Heart
                   a)  Pulmonary Circulation


                   •  Carries deoxygenated blood from the heart to the lungs.
                   •  In the lungs, carbon dioxide is removed and oxygen is absorbed.
                   •  Then, oxygen-rich blood returns to the heart.
                   •  Right side of the heart is involved.
                   •


                   b)  Systemic Circulation

                   •  Carries oxygenated blood from the heart to the rest of the body.
                   •  Delivers oxygen and nutrients to body cells.
                   •  Collects waste and carbon dioxide from the cells.
                   •  Left side of the heart is involved.

               Together, these two form Double Circulation


                   •  Blood passes through the heart twice in one complete cycle.
                   •  Ensures efficient oxygen supply and removal of waste.
