Circulatory system

• The circulatory system carries oxygen and nutrients to every cell in the body and removes waste products
• The heart pumps blood around the body in a double circulatory system
• 1. Deoxygenated blood flows into the right atrium and then into the right ventricle which pumps it to the lungs to undergo gaseous exchange
• 2. Oxygenated blood flows into the left atrium and then into the left ventricle which pumps oxygenated blood around the body
