Pumping blood to all the organs of the body is the primary function and that is why it is called as circulatory system. The blood supplies oxygen which is the primary nutrient for cells to grow and upkeep themselves. At the same time, blood also collects carbon-dioxide and the get these gases exchanged in lungs.
Four rooms, two small chambers on top and two larger chambers in the bottom are there for pumping the blood. The frequency at which the blood is pumped is calculated as heartbeats, which are represented as a number per unit time (normally per minute).
The performance can be studied in various parts of the body such as temple, near the jaws, the chest, wrist, ankle of the foot, etc. Manufacturers design different instruments in various shapes and sizes to study this rhythm. There are slightly heavier instruments that wrap around the thorax like shirts, whereas smaller ones are wound around the wrists. Some of them are like gloves covering the wrist and fingers.
