The Role of Energy in the Body

Discuss the Role of energy in the body?

In this essay I will discuss the role of energy in the body, and describe five different types of energy. I will see where energy comes from how it creates heat and how it breaks down food. I will also discuss what metabolism is and how much energy we need, and what effects we have in the body when we have too little and too much energy. Finally I will talk about the excess of energy and what diseases it can lead to and where energy is stored in the body.

Energy is the measure of ability of a body system to do work or produce a change, expressed usually in joules or kilowatt hours. No activity is possible without energy and its total amount, it cannot be created or destroyed but can only be changed from one type to another. The two basic types of energy are, potential energy, associated with the nature, position, or state, such as chemical energy, electrical energy, and nuclear energy. The other type of energy is kinetic, and that is associated with the motion, such as moving a car or spinning a wheel.

In our body’s we need energy so that we can do things that are possible such as movement of muscles, talk, activates and many other things that we do. Energy is needed to extract the oxygen from the areas in our body and diffuse it into our bloodstream. As warm blooded we can only digest food and function if our bodies are at a certain temperature and have enough energy, Energy is required to do this. Energy is the capacity to work in our bodies. That means doing everything that the body needs to do to stay alive and grow, Pumping across membranes, making new proteins, lipids, hormones, new cells, neural functions, contracting muscles, and replacing damaged or worn out components, absorbing nutrients, extracting wastes and pumping blood.

Supplying energy to support many functions of the body at work or play is one of the chief functions of food. This energy comes from fats, carbohydrates, and proteins in the food we...
