The Heart The heart is a very important organ in the body which acts as a pump to circulate the blood in the body. The failure of heart is the cause of many deaths. There are many techniques and instruments to measure functioning of heart and to diagnose any of its malfunctioning for treatment so as to avoid its failure. The cardiovascular system consists of heart, distribution system (arteries and arterioles), diffusing system (capillaries in contact with cells) and collecting systems (veins), The cardiovascular system is a closed hydraulic system. Blood pressure, flow and volume are measured by using engineering techniques.
