There are three parts of a polygraph machine. They are:
- the cardio-sphygmograph consisting of a blood pressure cuff placed on the arm that remains inflated during the test - measures blood pressure and heart rate
- the pneumograph consisting of two tubes filled with air, one placed around the chest and the other placed around the abdomen - measures respiratory rate
- the galvanograph which consists of electrical sensors attached to the fingertips - records the amount of perspiration produced

What are the parts of a polygraph machine?
A lie detector picks up changes in your pulse and heart rate. Generally when you tell a lie, your pulse will increase because you don't want to tell the person what you are hiding and consequently become nervous. It has been confirmed that a lie detector can not be trusted fully to determine whether you are lying or not.

Proper attachment of polygraph machine in human body?
A polygraph instrument measures three basic bodily functions but may also measure additional (optional) features. At a minimum, the polygraph must measure (1) relative blood pressure by placing a blood pressure cuff on the upper arm, (2) electrodermal response by placing metal plates on the fingers or self-stick pads on the palm of the hands, and (3) breathing patterns by placing two soft rubber tubes across the upper and lower abdomen. Additional features may also be measured, but these are the basics. - Michael Martin (President, Global Polygraph Network)

Do lie detectors test true?
Yes and no. What polygraph machines do is monitor specific biological functions such as pulse and skin temperature. The polygraph operator asks a series of test questions with known answers to esatblish a baseline for the subject. When humans lie there are a few typical responses, such as an elevated pulse. The polygraph operator decides whether or not the subject has responded honestly or not based on the changes in the measured functions.
Is the human body a machine?
Yes, some people consider the human body to be like a machine because it has various parts that work together to perform functions, similar to how a machine operates.
Is a computer a complex machine?
Yes it has many parts all doing different functions.
