Question

what happens in the body during stress? when the body is under stress, chemicals in the body react to help us alleviate, control, and eliminate the many symptoms that are associated with the condition. the chemicals released into the bloodstream are called epinephrine, norepinephrine, and cortisol. they affect the body by increasing heart rate, increasing oxygen delivery to the brain, dilating blood vessels in skeletal muscles, and increasing blood sugar levels. all of these effects enable a person to either fight back whatever is distressing him or her, or to flee. this is called the fight - or - flight response. during the chemical release, a persons memory becomes sharper and his or her senses keener, even as his or her body becomes less receptive to feeling pain. however, with prolonged stress, or chronic stress, these processes and reactions can cause serious damage to the body, injuring and even killing cells in the hippocampus, which is the area of the brain needed for memory and learning. what are the symptoms of stress? the symptoms of stress can surface at any time, in a variety of ways—physically, mentally, and emotionally. some of these include: what is the purpose of the second paragraph? a. to discuss the flight - or - fight response and its consequences in specific detail b. to teach the reader about the hippocampus and the areas most affected by stress c. to focus on how prolonged stress affects a persons senses and pain receptors d. to inform the reader of the chemical processes and reactions that occur in the body during stress

Explanation:

The second paragraph starts by stating that when the body is under stress, certain chemicals react and are released into the bloodstream. It then details what these chemicals are (epinephrine, norepinephrine, cortisol) and how they affect the body (increasing heart - rate, oxygen delivery etc.), and also mentions the fight - or - flight response. Overall, it focuses on the chemical processes and reactions during stress.

Answer:

D. to inform the reader of the chemical processes and reactions that occur in the body during stress
