each system functions independently. The cardiovascular system is made up of blood, the heart and blood vessels which are divided into arteries, arterioles, capillaries, venules and veins. (www.livestrong.com, 2013) Blood is a thick, red, slightly alkaline fluid and has 3 general functions; transportation, regulation and protection.

of gases take place (pulmonary respiration) between the alveoli and the blood, through the pulmonary capillaries. At this point the blood will gain oxygen and lose Carbon dioxide. (tortora 2011) It is the function of the red blood cells to transport oxygen around the body. Red blood cells contain a pigment called haemoglobin which attracts oxygen into the cell. (www.hematology.org) From the lungs the blood flows to the heart through four pulmonary veins. It enters into the left atrium
