What is a serous membrane and what lines the heart, lungs, and abdominal viscera? -
ANSWERThe thin, double-layered membrane that covers the walls of the ventral body

as the *pericardium,
-The serous membrane lining the *thoracic cavity* and *surrounding the lungs* is
referred to as the *pleura*
-The serous membrane that lines the *abdominopelvic cavity* and the *viscera* is
referred to as the *peritoneum.*
Body cavities w/ details visual - ANSWER
Homeostasis - ANSWERMaintaining a stable internal environment
-Depend on normal concentrations of water, nutrients, and oxygen, and normal body
temperature and pressure
*Positive feedback loop* - The output *enhances the original stimulus.* A good example
of a positive feedback system is *child birth.* During labor, a hormone called oxytocin is
released that intensifies and speeds up contractions. The increase in contractions
causes more oxytocin to be released and the cycle goes on until the baby is born. The
birth ends the release of oxytocin and ends the positive feedback mechanism.
*Negative feedback loop* - Almost all homeostatic control mechanisms are negative
feedback mechanisms.
-These mechanisms *change the variable back to its original state or "ideal value".*
- The control of blood sugar (glucose) by insulin is a good example of a negative
feedback mechanism. When blood sugar rises, receptors in the body sense a change .
In turn, the control center (pancreas) secretes insulin into the blood effectively lowering
blood sugar levels. Once blood sugar levels reach homeostasis, the pancreas stops
releasing insulin.
