1) Define the following terms: homeostasis, negative feedback loop, and positive feedback loop. Why are negative feedback loops more common than positive feedback loops? Provide an example of a homeostatic mechanism that uses a negative feedback loop.

2) What are the requirements for life? List and define each requirement.

3) Give the definition of a body system. Then provide an example of a disease or condition that impacts multiple body systems. Identify the body systems impacted and how they are connected to one another.

4)Describe the hierarchical structure of anatomy. How does this hierarchy relate to the approach we take in studying anatomy and physiology? Lastly, give an example of how the anatomy (structure) of a body part is related to its physiology (function).

5) Integration of body systems. Provide an example of a disease or condition that impacts more than one body system.What is the disease? What body systems are involved? Describe how the functions of the two systems are integrated to work together. How does this disease process illustrate a loss of homeostasis?
