Energy laws
Energy can be defined as the capacy to do work.

The conservation law
Energy cannot be created or destroyed, but it can be transferred or transformed from one form to another (including transformation into or from mass, as matter). The total amount of energy in a closed system never changes.
Energy in a system may be transformed so that it resides in a different state. Energy in many states may be used to do many varieties of physical work. Energy may be used in natural processes or machines, or else to provide some service to society.

Example: when we eat a rich meal with carbohydrates and some vitamins before exercising it will provide our bodies with energy to run faster etc.…therefore it gives us energy which is sourced from food.

Energy forms:
  * Chemical energy.
  * Heat energy.
  * Light energy.
  * Sound energy.
  * Electrical energy.
  * Nuclear energy.

  * Energy is needed not only for muscle movement but for many body functions such as blood, Lymph and tissue fluid circulation, breathing, making new cells for breathing, making new cells for growth and repair, transmitting nerve impulses and digesting food.

  * Catabolic reactions are the chemical reactions which breakdown molecules to release energy.

  * Anabolic reactions are the ones who’s building complex molecules from simple substances and using energy.
Body systems and energy metabolism
The activities involved in supplying energy to the cells include the roles of the cardiovascular, respiratory and digestive systems.

Digestive system:
The digestive system is responsible for taking in food...
