Resistive—body actively resists stressors (corticosteroids)
Exhaustion—more intense arousal but this leads to physical exhaustion and physical disorders

Stress and the Immune System
Psychoneuroimmunology—studies interaction between nervous system, endocrine system, and immune system
Stress leads to suppressed immune function
Chronic stress tends to have more influence
Stress-weakened immune system increases likelihood of illness
![Page 24: Chapter 12](https://reader036.vdocument.in/reader036/viewer/2022062315/56815259550346895dc08ce7/html5/thumbnails/24.jpg)
Your immune system battles bacteria, viruses, and other foreign invaders that try to set up housekeeping in your body. The specialized white blood cells that fight infection are manufactured in the bone marrow and are stored in the thymus, spleen, and lymph nodes until needed.
