Why is the body temperature of a person different in different organs?

The temperature on the human body depends on the blood supply to a particular organ and on how deeply it is located in the body. For example, the heart, liver and other internal organs have the highest temperature, since they have excellent blood supply and, due to this, a higher temperature. The highest temperature on the human body is on the head and neck, as they are the best supplied with blood. The smallest is on the limbs (arms and legs), since they are the farthest from the viscera and are supplied with blood by the smallest vessels.
