Functions of the cardiovascular system

• What are the 3 functions of the cardiovascular system?

  • Transport of oxygen, carbon dioxide and nutrients
  • Clotting of open wounds
  • Regulation of body temperature
• Transport of oxygen, carbon dioxide and nutrients

  • blood delivers oxygen and carries away waste products such as carbon dioxide and Latic acid
  • during exercise the need to remove these waste products from the body increase
• Temperature regulation

  • too hot vasodilation takes place and too cold vasoconstriction takes place
  • during exercise the body regulates more heat to it is even more important to regulate temperature so people don't overheat
• Clotting of open wounds

  • Platelets in the blood form clots
  • this stops the body losing an excessive amount of blood
  • during exercise the risk of a cut is increased therefore clotting is important in ensuring that injuries are not life threatening
