GCU BIO-201 Midterm Exam questions with verified answers
A+ Grade
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
