Homeostasis 1:
basic feedback mechanisms - pH balance and thermoregulation
"To improve is to change; to perfect is to change often"

Introduction
The human body is constantly in a state of change towards the optimum conditions for essential biological functions. This is known as homeostasis.
This section acts as the introduction to the two part analysis of the Homeostasis unit: Part 1: Basic Feedback Mechanisms Part 2: The Nervous System |
This section will delve into the basic feedback mechanisms with a focus on thermoregulation and pH balance.
A detailed break down is as follows:

Curriculum Expectations
Overall Expectations
E2. Investigate the feedback mechanisms that maintain homeostasis in living organisms; E3. Demonstrate an understanding of the anatomy and physiology of human body systems, and explain the mechanisms that enable the body to maintain homeostasis Specific Expectations: E2.1 use appropriate terminology related to homeostasis, including, but not limited to: insulin, testosterone, estrogen, nephron, dialysis, pituitary, synapse, and acetylcholine E2.2 plan and construct a model to illustrate the essential components of the homeostatic process (e.g. create a flow chart that illustrates representative feedback mechanisms in living things) E3.1 describe the anatomy and physiology of the endocrine, excretory, and nervous systems, and explain how these systems interact to maintain homeostasis E3.3 describe the homeostatic processes involved in maintaining water, ionic, thermal, and acid-base equilibrium, and explain how these processes help body systems respond to both a change in environment and the effects of medical treatments (e.g. the role of feedback mechanisms in water balance or thermoregulation; how the buffering system of blood maintains the body’s pH balance; the effect of medical treatments on the endocrine system; the effects of chemotherapy on homeostasis) |
