1. Endocrine System
continued

2. Define:Homeostasis
Defined as the maintenance of the body’s internal environment (blood and interstitial fluid) between specific limits.
Endocrine System contributions to homeostasis
Parameters include:
Temperature
Blood pH
Glucose levels
Water balance (osmoregulation)
Hormone levels
CO2 & O2 levels….etc

3. State that the endocrine system consist of glands that release hormones that are transported in the blood

4. Explain that homeostasis involves monitoring levels of variables and correcting changes in levels by Negative Feedback Mechanisms

5. Explain the control of body temperature, including the transfer of heat by the blood, and the roles of the hypothalamus, sweat glands, skin arterioles and shivering

6. Temp control images

7. Explain the control of blood glucose concentration, including the roles of glucagon, insulin and alpha and beta cells of the pancreatic islets

8. Distinguish between type I and type II diabetes Diabetes mellitus:a disorder in which blood sugar (glucose) levels are abnormally high
Type 1
Onset: usually during childhood
BETA-cells produce insufficient insulin
Diet alone can not control the condition
Type 2
Onset: usually after childhood
Target cells become insensitive to insulin
Low carb. Diet can help control the condition
