How does the blood move?

It travels to lungs and picks up the oxygen.

Pros of double circulated system

  1. Oxygenated and deoxygenated blood is kept seperate

  2. Allows for specialisation of blood vessels

  3. Each circuit of blood passes through capillaries once, this maintains fast flow and high pressure
