Energy Metabolism: Cardiovascular and Digestive Systems 
Task 4 (P4)
P4: Explain the physiology of two named body systems in relation to energy metabolism in the body
In your role as a health and social care professional in a respite care home you have been asked to prepare a booklet to explain to your client group how the body requires and uses energy.
You should produce an information booklet that gives an overview of how energy is produced and utilised in the body.
You booklet should include information on:
* Energy forms * Energy laws * Why the body needs energy and where does it come from. * An explanation of the physiology of two named body system, and their role in the utilisation of energy in the body. An examples of 2 systems the you could discuss are as follows:
THE CARDIOVASCULAR SYSTEM, THE DIGESTIVE SYSTEM
Fredrick’s response on forms of energy and P4
Examples of energy/Chemical, heat, light and motion.
Examples of chemical energy are digestion of food products. It is not reversible. Chemical processes cannot be reversed as food cannot return to its natural state.
Heat energy when rubbing hand, heat energy is created by the friction.
Light energy, torch changes from chemical (battery) to light.
Motion, a car moving from one point to the other.
Energy can neither be created nor destroyed, but can be transformed from one form to the other. (Example provided, e.g. from potential to kinetic).
DIGESTIVE SYSTEM
Digestion is a chemical process whereby food substances are broken down into soluble unit and absorbed in the blood stream by a process known as assimilation. The digestive system is made of different tract as seen in figure 1.2. All these parts help in the digestion of food.
Digestions start from the mouth. Firstly, ingestion is the process of taking food via the mouth. When the food enters the mouth the food is then chewed, mixed with salivary gland, which produces and enzyme called salivary amylase. This enzyme breaks the food
