The Cardiovascular System

Cardiovascular System
  • The cardiovascular system is the body’s blood transporting network of arteries, veins and vessels.

  • It is responsible for carrying oxygen and vital nutrients to all parts of the body and removes harmful waste products from tissues.

  • The heart pumps blood through arteries and smaller vessels to all parts of the body.

  • The blood returns to the heart through veins.

  • The pulmonary arteries are the only arterial vessels that transport deoxygenated blood.

  • Blood makes a full circuit of the body in about one minute.

  • At the core of this system is the heart .

  • It is about the size of a grapefruit and located to the left of the centre chest.

  • It needs a generous supply of oxygen which is supplied by the large supply of blood.

  • Blood that flows through the heart cannot supply it with oxygen and nutrients - so it has its own network of blood vessels called the coronary system.
