Keys to Maintaining Balance in Organisms by Interaction Regulating Internal Conditions
External Force Exercise Fright Danger Threat Temperature Environment
Extended Learning What other systems might be involved in temperature regulation? Maintaining Homeostasis involves the interaction of many systems. How does change in one system affect another? Are these Automatic or Behavioral?
Key Body Systems Circulatory System –Provides path to internal systems of the body Respiratory System –Provides for gas exchange CO2 for O2 Nervous System –Controls and coordinates bodys responses Endocrine System –Secretes Hormones into the blood system for stress recovery. Needed – Urinary System –Removes wastes produced from work
Nervous System Keys Sense –Stress applied by external force (ie exercise) Respond –Controls and Coordinates the bodys response –Integrates the activities of the organ systems
Circulatory System Keys Sense –Monitor Stimuli (ie cold) –Message to Brain Respond (involuntary or automatic) –Change in Blood Flow –Vessels Constrict –Major organs protected –Extremities sacrificed
Endocrine System Keys Sense –Needed Hormones for stress reduction Respond (automatic) –Glands manufacture and secrete hormone into the bloodstream
Respiratory/Urinary System Keys Exchange of Gases between the air and the circulating blood Exchange of cell wastes (toxins) between the blood and external environment
Behavioral Keys Sense –External Force Respond –Various (view video)
