Influence of the 21st century lifestyles on homeostatic mechanisms

In today’s society, we are constantly reminded that everything we consume, are exposed to or come in contact with may have serious effects on the way our body systems function. Asthma, diabetes A and diagnosis of behaviour disorders are increasing in today’s society (Australian Bureau of Statistics, 1999). Links between drug use and schizophrenia have been suggested (The Australian, November 2005). Excess consumption of food (over nutrition) is a major concern. One study has shown, ”Irish men already have the highest body mass index (BMI) in Europe, while Irish women rank third. Almost one-fifth of the world’s obese adults (118 million) live in Ireland and five other high-income English-speaking countries – Australia, Canada, New Zealand, the UK and the US.

Too much salt in the diet can raise blood pressure which increases the risk of heart disease and stroke. A reduction in average salt intake from 8g to 6g per day is estimated to prevent over 8000 premature deaths each year.”( )

STUDENT NAME:

PART B (Word limit for Question 3, Part B - 3000 words):

1. Develop a hypothesis to account for the effects of one of the above on the homeostatic mechanisms in the human body.

2. Formulate questions and collect data that supports and refutes your hypothesis e.g. statistics, graphs, articles.

3. Describe the normal homeostatic conditions of the affected system/s of the body. Compare and contrast these with the effects of the influence you chose to examine on the bodydown to the cellular level. These effects should include short (up to 24 hours), mid (>24hours – 2 weeks) and long term

Understanding Biology

Description of condition

Identify key biological ideas relating to your lifestyle decision. Make special reference to systems, organs, tissues and cells as well as mid, short and long term effects. / Identifies key biological ideas and concepts relating to: body systems, organs, tissues and cells and mid, short and long term effects / Identifies important biological concepts relating to body systems, organs and tissues and short, mid and long term effects / Identifies some biological ideas/concepts relating to body systems and short, mid or long term effects / Identifies obvious ideas and concepts that may contribute to the task / Mentions familiar ideas associated with the subject matter of the task
Link the biological ideas relating to body systems, organs, tissues and cells to the mid, short and long term effects that you have found. / Makes links between key biological ideas/ concepts (relating to body systems, organs, tissues and cells) and mid and short and long term effects / Makes links between identified biological ideas and short and mid or long term effects. / Illustrates cause and effect relationships by linking biological information about a body system to a short or mid or long term effect / Outlines how a short, mid or long term effect may be related to an aspect of a body system / Lists some short, mid or long terms effects
Outline a possible interpretation or link between pieces of information that follows logically from the information you have researched. Make sure you explain the link clearly / Develops at least one novel and likely interpretation or link between pieces of discrete information / Suggests a likely interpretation or link between pieces of information / Assembles relevant information into a cohesive concept / Identifies information that contributes to an understanding of the lifestyle decision / Lists some relevant information
