A-level Applied Science/Energy Transfer Systems

About this Unit
From the AQA Specification:

 In this unit you will learn about:
 * the structure and function of the circulatory and respiratory systems including the processes involved in respiration;
 * some methods of taking physiological measurements related to the circulatory and respiratory systems, and the uses of these in monitoring health and for diagnosis of illness;
 * examples of imaging methods used in monitoring health and in diagnosis, the advantages and disadvantages of using these methods, and which are best suited to particular situations;
 * ethical issues relating to the monitoring, diagnosis and treatment of the circulatory and respiratory systems;
 * relating information from measurements or monitoring to what is happening in the organs and systems involved;
 * some applications of energy transfer both in the body and in wider contexts;
 * the meaning of the term efficiency, how to calculate the efficiency of a system and know that there is a fundamental limit to efficiency.

How you will be assessed
In this unit you will be required to complete an external examination of 1½ hours duration. The examination will consist of a series of compulsory short answer questions and will be marked out of 80. The examination may also contain a comprehension exercise.

You will be assessed on your knowledge, understanding and skills relating to choosing and using materials.
