The cardiovascular system
The myocardium, commonly referred to as the heart, acts as a pump for transporting blood around the body via a collective system, known as the cardiovascular system. This system has various components; blood vessels; mainly arteries, veins and capillaries. The cardiovascular system has four main functions within the body. Firstly to transport dissolved oxygen, hormones, nutrients, salts, enzymes and urea to cells located around various places within the body, whilst at the same time eliminating any waste products such as carbon dioxide and water. Secondly, to protect the body from infection and blood loss. Thirdly, to distribute heat around the body to enable a healthy temperature of 37oc and finally to aid the body to maintain fluid balance. This ‘human pump’ can be regarded as two pumps. The fist sized organ contains two muscular chambers; the upper chamber; the atrium and the lower; the ventricle. The right side of the heart pumps deoxygenated blood from the veins to the lungs for oxygenation, whilst the left side pumps oxygenated blood from the lungs to the body. It is important to note that the two sides are separated by a septum. The blood flows through the heart twice within one cycle, this is known as ‘double circulation’.
The cardiovascular system carries oxygen and glucose to the cells and transports waste products such as co2 and urea away from the cells and to other parts of the body, such as the lungs and kidneys. Adenosine triphosphate, also known as ATP, is a chemical energy that is produced when nutrient molecules are burnt. ATP is constantly being produced on a daily basis due to the breakdown of glucose. Glucose is a sugar which is the main source of energy for the body. Glucose is broken down and the energy from the glucose molecule chemical bonds are released and utilized by the cell
