IMPFT105K Principles of human biology and food metabolism

 

Overview

This standard is about the underpinning knowledge surrounding human biology and food metabolism. It covers the background knowledge surrounding how food is assimilated and used by the body.

This standard is for you if your role requires you to have an understanding of the biological processes involved in assimilating and digesting food in the body.

 

Knowledge and understanding

You need to know and understand:

1 the structure of the human alimentary system and associated organs

2 what the functions of the component parts of the human alimentary system are

3 how food is physically passed through the alimentary system

4 which food nutrients are important in contributing to easing the passage of food through the alimentary system

5 how food components are digested by enzymes and other digestive substances

6 the absorption of food components across the wall of the human alimentary system

7 the role of micro-organisms in the functioning of the large intestine

8 how water is re-absorbed across the wall of the large intestine

9 what the components of faecal waste matter are

10 the role and functions of the gall bladder and bile

11 the role and functions of the liver

12 how and in what form absorbed food components are stored and handled by the body

13 which food nutrients are unable to be stored in the body

14 how a balance of available nutrients is maintained in the blood

15 how food energy value is measured

16 which food types are high in available food energy and which are not

17 how high energy food components are stored in the body for immediate and longer term use

18 how excessive food calorie intake is converted into fatty tissue

19 how metabolic rates can influence the gain and loss of fatty tissue within the body

20 how muscle activity converts food components into energy for movement

21 what the waste products of energy usage by muscles are

22 how waste products in the blood are disposed of by the body
