Endocrine System 6. 6.5 continued

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

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

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

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

Temp control images

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

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
