Nataly_w [17]

Answer:

C. the sympathetic division of the autonomic system.

Explanation:

The sympathetic nervous system is one of the divisions of the autonomic nervous system that controls involuntary body functions in the body. The sympathetic nervous system is said to stimulate the fight-or-flight response of the body when the body senses threat, or is exposed to a stressor. These  fight-or-flight responses are generated in the body in form of physiological changes in order to put the body at top alert to focus on dealing with the stressor.

Physiological changes that are stimulated by the sympathetic nervous system as fight-or-flight responses include dilated pupils, inhibited digestive activity, increased respiratory rate, and release of glucose from the liver, which are all stated in the question. It is the sympathetic division of the autonomic nervous system that controls all these activities.

const2013 [10]
We would probably look for viral antibodies, in the person's blood. It's kind of like when we test for AIDS. That's a viral disease. What we do is we look at the person's blood. If we see antibodies that match up to the HIV, then we know that the person is HIV positive, and will probably develop AIDS sooner or later.sometimes like doctors we experiment by signs and symptoms as in the 3rd response then we experiment by treating with anti viral drugs like Dr House to see if the patient improves and if we do not see an improvement or see the side effects of the drugs then we ll go in for another diagnosis this method is more like experimenting on the patient and only meant for the very brave. i hope to one day be able to do my diagnosis like that instead of fearing death that much and not having the courage to speculate as a doctor which is what most doctors do and get lucky. i would speculate and try to know as much anatomy,physio,and pathology
