Does the body store thermal energy?

The body is capable of storing chemical potential energy and thermal energy internally. Remembering that thermal energy is just the kinetic energy of atoms and molecules, we recognize that these two types of energy are stored microscopically and internal to the body.

How does the human body consume energy?

Like any other sophisticated device flooding our mainstream, the human body requires and consume energy in a similar way and understanding its inner-workings is essential. The human body carries out its main functions by consuming food and turning it into usable energy.

What is the efficiency of the body?

In fact the efficiency of the body in such a situation is zero! The digestive and metabolic process is essentially oxidation of food so it requires oxygen just like oxidation of fuel in an engine requires oxygen. Therefore, we can determine the the actual chemical potential energy consumed during different activities by measuring oxygen use.

Do all organs consume the same energy per gram?

The idea is that each organ has a particular energy requirement in the body at rest, and this requirement is a product of the size of the organ and its energy consumption per gram. The assumption is that all livers, for example, consume the same energy per gram. Similarly for the heart and other organs.

Where does energy go in the body?

The largest fraction of energy goes to the liver and spleen, with the brain coming next. About 75% of the calories burned in a day go into these basic functions. A full 25% of all basal metabolic energy consumed by the body is used to maintain electrical potentials in all living cells. (Nerve cells use this electrical potential in nerve impulses.)
