Human Anatomy And Physiology


The Autonomic Nervous System can be challenging to understand because it is connected to virtually every body function in opposite ways. We are going to explore the physiology of the ANS in this discussion by looking at specific examples of how it works.

Initial post: For your first discussion post, describe how the parasympathetic nervous system influences one function in your body. For example, the parasympathetic nervous system causes decreased blood pressure. If you chose this body function, you would describe the physiology behind the decreased blood pressure. How does it happen? What occurs in the heart/blood vessels? Which scenarios or external factors would cause the parasympathetic nervous system to activate this response?


There are few individuals in the world who have not been impacted by Coronavirus (COVID-19).

For your initial post, do some research on coronaviruses and then share what you learn about how a typical coronavirus compares to COVID-19. What does it mean for a virus to “mutate” and what could this mean to the process of developing immunity? Many people have chosen to get vaccinated while others have not. What do you think are the benefits of getting vaccinated and are there any scientific or medical reasons (exclude personal or religious reasons) that could serve as reasonable contraindications to being vaccinated or that would justify prolonging this medical intervention?
