M1. Discuss the role of energy in the body
The three systems in our body that work together are cardiovascular, respiratory and digestive systems which supply energy to the cells of the body. I will be describing their role of energy in the body system; also I am going to explain the physiology of the three named body systems in relation to energy metabolism.
Respiratory System
The respiratory system consists of tissues and organs in our body which are formed into groups. The system includes airways, lungs, blood vessels and muscles attached to work together so an individual can breathe. The respiratory systems primary function is to supply oxygen to all the parts of the body. Every time we inhale oxygen we have to exhale carbon dioxide.

The energy release from glucose or ATP during a chemical reaction is an example of chemical energy. This energy it is used for making proteins, making muscles to move, for heat and hormones.
The food that we eat is one example of chemical energy, which is stored in the bonds of the molecules that make up food. When we eat the food, the large molecules are broken down into smaller molecules that can be used by the cells in the body. The process of breaking down the food and using it by our cells is called respiration. During this process the chemical energy is converted to heat, kinetic energy and other forms of chemical energy (like the one stored in the fat cells in our body).
Another example of converted energy we can find in our movement. For this to happen we need the chemical energy first, which makes the electrical energy. This is converted to electrical energy for the nerve production, which goes back to chemical energy for the muscle contraction. At the end, the thermal energy which has the waste energy is converted to kinetic energy which produces the movement.
M2. Discuss the probable homeostatic response
Homeostasis is the maintenance of a constant internal environment. The maintenance of homeostasis can occur through the nervous system or through chemical stimulation and changes are achieved and controlled by the homeostasis regulation mechanisms
