The heart is an organ that beats continuously to act as a pump for the transport of blood, which carries other substances with it. The heart pumps the deoxygenated blood to the lungs for oxygenation and receives oxygenated blood from the lungs. It pumps the oxygenated blood to different parts of the body. There is double circulation in a human heart that creates lub- dub sound.

Insolation is vertically incoming solar energy intercepted by the Earth and it covers up less space but we feel more heat there when it goes up from equator towards poles, the Sun rays become slanting. Therefore, the temperature decreases in the same manner.
