Mrs. Jones, who has been caring for her terminally ill mother for a year now, has continued to work at a demanding job, as well as parent three active teenagers. These long-term stressors should <u>decrease</u> the number of NK cells, thereby<u> </u><u>impairing</u> immune system functioning.

<u>Explanation:</u>

In this adaptive cycle, the two major structures at work are the nervous system particularly the brain and the immune system.Prolonged stressful environments reduce cytotoxic potential at NK. There is a component P, which facilitates the improvement in macro-phage cytokine formation under stressful circumstances.

Acute stress improves activation of T cells by means of a beta 2–adrenergically mediated cycle that is blunted throughout chronic stress. Psychological stress affects the ability of the immune system to generate antibodies in reaction to a vaccine and thus renders the organism more susceptible to infection.

1. Where in the digestive system do the amounts of glucose, amino acids, and fatty acids increase?
natima [27]
The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.
