You have offered to volunteer for a UK charity who work to raise awareness and
provide patients with support and up-to-date, easy to understand information about
Vocational Scenario or
disorders of homeostasis. You have been assigned to research common homeostatic
Context
disorders and produce an illustrated report that details normal and abnormal functioning
of the endocrine system and the treatments available to address disorders.
Using correct scientific terminology, produce a detailed illustrated report for your
charity that includes:
A clear explanation of what homeostasis is, why it is necessary and how it
occurs. The report must include the regulation of: Temperature (vasodilation
and vasoconstriction of arterioles, pili erector muscles, sweating and shivering),
Blood glucose levels (the role of alpha and beta cells in the Islets of
Langerhans and the liver), and osmoregulation (the role of nephrons, Cl-, Na+,
K+ ions and the hormones ADH, ANP, angiotensinogen and aldosterone).
Illustrate your report with detailed, annotated feedback diagrams describing
Task and explaining where each hormone is secreted, how the hormones act on the
target organs and the responses involved.
Your report must go on to analyse and describe the consequences to human
health that may result when homeostatic mechanisms do not work properly.
You must include at least one example for each of the 3 homeostatic
mechanisms studied e.g., dehydration, hyperglycaemia, hypoglycaemia,
diabetes, hypothermia or syndrome of inappropriate ADH. You must also
describe methods to correct the dysfunction and the homeostatic consequence
of the treatment.
To finish your report, you should give a detailed explanation of how the
homeostatic mechanisms are interrelated, discussing the effects each system
has on the others and their overall impact upon human health.
Checklist of evidence An illustrated report that includes:
required An explanation of what homeostasis is and why it is necessary.
An explanation and annotated feedback diagrams of thermoregulation, water
balance and glucose levels including thorough consideration of the secretion of
different hormones and their mode of action on target organs and the responses
those organs then carry out.
, An analysis of the effects of at least one dysfunction of each of the 3
homeostatic mechanisms of thermoregulation, water balance and glucose
levels.
A discussion of the interrelation of homeostatic mechanisms and the impact
they have on each other.
Criteria covered by this task:
Unit/Criteria
To achieve the criteria, you must show that you are able to:
reference
B. D2 Analyse the impact of homeostatic dysfunction on the human body
B. M2 Explain the role of hormones in homeostatic mechanisms
B. P2 Describe how homeostatic mechanisms maintain normal function

Brief
Unit 9: Homeostatic control of body systems
In this assignment I will be providing an explanation of what homeostasis is, why it is necessary and how it
occurs. As well as this, I will be providing a report about the homeostatic control of body systems which will
include the regulation of temperature, blood glucose levels and osmoregulation. I will illustrate this report
with detailed, annotated feedback diagrams describing and explaining where each hormone is secreted, how
the hormones act on the target organs and the responses involved. My report will analyse and describe the
consequences to human health that may result when homeostatic mechanisms do not work properly and will
give a detailed explanation of how the homeostatic mechanisms are interrelated.
The process by which an organism maintains a steady, stable environment despite changes in internal and
external factors is known as homeostasis. Body temperature, blood glucose concentration, and water levels
are all examples of that in the human body.
Homeostasis is crucial because it maintains ideal conditions for enzyme functioning and all cell activities
throughout the body. Homeostasis typically involves negative feedback loops that counteract changes of
various properties from their target values, known as set points.
