Body Cavities contain what?	Viscera (organs)
The heart is covered by a serous membrane called the?	Visceral Pericardium
All body systems working together to maintain a stable internal environment is called?	State of equilibrium
Homeostasis limits the fluctuation of internal conditions to keep conditions close to a?	Set Point
Automatic response and localized control within a cell, tissue, or organ to some environmental change?	Autoregulation
Control that is mediated by the nervous system or the endocrine system?	Extrinsic Regulation
Receives the stimulus and sends a signal to the control center?	Receptor
Receives the signal, processes the signal, and sends instruction to the effector?	Control Center
Carries out the instructions sent by the control center?	Effector
A _________ ___________ _________________ exists when opposing forces are in balance?	State Of Equilibrium
What are the three components of a homeostatic regulatory mechanism?	1. Receptor 2. Control Center 3. Effector
Physiological systems are continually adapting and adjusting to changing conditions through a process called?	Dynamic Equilibrium
Enhances or accelerates the original change (conditions get even farther away from the set point), Causes further deviation from homeostasis through the establishment of a?	Positive Feedback Loop
The initial stimulus produces response that enhances, amplifies, or accelerates the original change? Example: blood clotting	Postive Feedback
The response of the effector opposes or negates the original change caused by the stimulus. Returns condition back to the set point, causes a return to homeostasis, This is the normal type of homeostatic control and the most common? Example: Sweating to cool body temperature that has gotten too high.	Negative Feedback

Where is the Parietal Pleura?	Serous membrane lining the wall of the cavity in the lungs
Where is the Visceral Pleura?	Serous membrane lining the organ of the lungs
Where is the Visceral Pericardium?	Serous membrane lining the organ of the heart
Where is the Parietal Pericardium?	Serous membrane lining the wall of the cavity in the heart
