The cardiovascular system is made up of the blood, heart, arteries, veins, and capillaries. This specialised transportation system delivers oxygen, nutrients and metabolic waste products to tissues and cells throughout the body. Tucker (2000) suggests that “pulmonary circulation is the transport of de-oxygenated blood from the heart to the lungs and back again; systemic circulation is the transport of oxygen-rich blood from the heart to the body and back”. This is referred to has double circulation.

The heart, a hollow muscular organ is divided into four chambers. According to Cohen and Taylor (2009) “The upper chambers are the atria, these are mainly blood-receiving chambers. The lower chambers, the ventricles, are the forceful pumps” (p.245). The muscle wall that partitions the left side of the heart from the right is called the septum. The walls of the atria are thinner than those of the ventricles. The left ventricle has a much thicker myocardium than that of the right. This is because the left ventricle is responsible for pumping
