The 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.
