Tasks for Reading week – June 2014
Unit 14 – The Healthy Body
You will find the specification for this Unit in the attached documents.
Task 1:
 Read through the specification for Unit 14 carefully to familiarise yourself with the topics.
 Set up a folder for the Unit, with separate (labelled) section headings eg Homeostasis, Cellular
Respiration, cardio vascular system, pulmonary system, Blood, Digestive System, Diet
 Find out what each of your section headings mean (if you don’t already know)
Task 2:
 Read the section carefully on How basic homeostatic mechanisms maintain a healthy body
The human body is organised into cells, tissues and organ systems. They interrelate with each
other to enable the body to function. Cellular, tissue or organ activity can be monitored to provide
information about how effectively any particular individual is able to perform under different
conditions.
You should know:
• the function of the component parts which make up the cardiovascular system – how these parts
function individually and how the system functions as a whole. You should be aware of common
defects of the heart and apply your knowledge of the structure of the heart to these defects;
• the function of the component parts which make up the pulmonary system – how these parts
function individually and how the system functions as a whole;

Use the internet and the Biology textbook issued in lessons to research and make your own notes
on:
 Definition and examples of Cells, tissues and Organ Systems and their function
 Component parts of the cardiovascular system (heart, blood vessels etc) and their
functions
 Structure of the heart
 Common defects of the heart
 Component parts of the pulmonary system (trachea, bronchi, alveoli etc) and their
functions
