ANSWERS/NEWEST UPDATE!!
Describe the difference between Anatomy, Physiology, and Pathophysiology. - (Correct Answer)-
Anatomy: Study of Structure
Physiology: Function
Pathophysiology: mechanisms of disease
Describe the six levels of structural organization (from least to most complex) of the human body
and how they interact - (Correct Answer)-1. Chemical Level
2. Cellular Level
3. Tissue Level
4. Organ Level
5. Organ System Level
6. Organism Level
Describe Negative Feedback and its purpose in maintaining Homeostasis - (Correct Answer)-the
body reacting to something to reverse or negate it to retain or revert back to homeostasis
Describe Negative Feedback and it's relation to a Receptor, Integrator, and Effector. - (Correct
Answer)-Receptor senses the issue
Integrator processes the information and compares it to what it should be
Effector carries out the corrective action
Describe Positive Feedback - (Correct Answer)-enhances the effect of the stimulus so that the
whole homeostatic control process continues at an even faster rate; i.e. birth labor or blood
clotting
Give an example of Positive Feedback - (Correct Answer)-childbirth
