Disorders of the heart
The cardiovascular system is an elaborate network that performs 2 major tasks. Firstly it delivers oxygen and nutrients to body organs and secondly it removes waste products of metabolism from tissue cells.The major components of the heart are a hollow muscular pump and a circulatory system of large and small elastic vessels that transport blood throughout the body. The heart is the central organ of the cardiovascular system and it is located between the two lungs in the middle of the chest, although two-thirds of the heart lies to the left of the breastbone and one-third to the right. The adult heart is approximately the size of two clenched fists and it is shaped like a cone, weighing between 7 to 15 ounces depending on the size of the individual. The human heart is divided into four chambers - the right atrium and the right ventricle and the left atrium and the left ventricle. The walls of the chambers are made up of myocardium muscle that contracts rhythmically under the stimulation of electric currents. A wall of muscle called the septum separates the left and right atria and the left and right ventricles from each other. (See Appendix 1a)
