1. Identify the three components of a homeostatic system AND explain the role of negative feedback (also called "reinforcing feedback") in maintaining homeostasis. 2. At the level of detail as was used in class, describe how the human body thermoregulates, with reference to all pertinent organs. 3. A person's pituitary gland stops functioning. Describe how this would likely affect osmoregulation. 4. At the same level of detail as was used in class, describe how protein is digested, with reference to all pertinent organs, acids, and enzymes. 5. An adult human engaging in intense physical activity only needs to consume between about 6 and 8 ounces of protein (170 - 225 g) per day. Describe what happens to that protein AND what would happen to any extra protein that was consumed.

Identify the three components of a homeostatic system AND explain the role of negative feedback (also called "reinforcing feedback") in maintaining homeostasis.
Adi S.
Explain the concept of physiological stress. Explain the concept of homeostasis. The four components of a negative feedback loop are the stimulus, the sensor, the control center, and the effector. Tell the role of each component in the negative feedback loop. Draw a negative feedback loop showing the relationship between each component of the loop. Explain what would happen if secretion of a body chemical controlled by a negative feedback system became too great. Tell which two human body organ systems are responsible for homeostatic control. Explain the reason maintenance of homeostasis is essential for living organisms. Explain the reason positive feedback mechanisms, while useful, are NOT homeostatic.
Describe the parts of the homeostatic mechanism and explain how it is used to maintain conditions for life. Think about the parts of the homeostatic mechanism... choose one of the following real-life examples and explain how it illustrates the concept of the homeostatic mechanism. You should identify the stimulus, receptor, control center, effector, and expected results for the chosen example. You should also predict what would happen if there was a breakdown in the homeostatic mechanism. You may need to do a little bit of outside research to reply to this prompt... although you are expected to identify the basic parts of the homeostatic mechanism using your example, you are not expected to understand the mechanistic details of your example. Choose one: Blood glucose levels, Blood pH levels, Body temperature, Blood pressure.
