What is Double Circulation?

Double circulation is a pathway followed by blood in which it travels throughout the different organs of the body through the veins and arteries. This type of circulation in humans is closed, hence a closed circulatory system exists as the flow of blood is in closed blood vessels. This system is hence responsible for transporting nutrients, gases and other wastes.

Double circulation is the most effective circulation wherein blood flows in two pathways:

  • Systematic pathway – oxygenated blood travels from the left side of the heart to all other body parts wherein exchange of nutrients, gases etc occurs, carrying the deoxygenated blood back again to the right side of the heart. 
  • Pulmonary pathway – carries deoxygenated blood from the right side of the heart to the lungs wherein gaseous exchange occurs in the lungs making the blood oxygenated
