Document Summary
The field that explores connections among psychological factors (such as attitudes and emotions), the nervous system and the effect it has on the immune system. Acute stressors can produce change in immune system functioning. Chronic stressors are associated with an increased stress response = shuts down the immune system. Positive social circumstances(social support) and low stress associated w/ increased ability to fight cancer. The immune system: antigens = foreign invaders immune system is a series of organs that protect antigens from effecting body. Mounting an immune response: the body has a few ways to protect itself from invasion. Non-specific cells & substances that attack all invaders. Antibodies(proteins made by body to protect against antigens) and cells specifically tailored for the antigen(specific viruses) Markers of self: at the heart of the immune response is the ability to distinguish between self and non-self(knows what to attack vs what not to)
