Final answer:
The wellness model recognizes that health is a state of optimal well-being encompassing various dimensions. It acknowledges lifestyle choices, diet, and access to basic resources as factors contributing to health and illness. In the context of the immune system, the wellness model also recognizes the importance of distinguishing between wellness and un-wellness by recognizing threat and initiating appropriate responses.
Step-by-step explanation:
The wellness model recognizes that health is not just the absence of illness, but a state of optimal well-being that encompasses physical, mental, emotional, social, environmental, and spiritual dimensions. It recognizes that various factors contribute to health and illness, including lifestyle choices, diet, and access to basic resources.
For example, the Well-Being Index survey covers six areas of health and wellness: Life Evaluation, Emotional Health, Physical Health, Healthy Behavior, Work Environment, and Basic Access. This survey measures the well-being of U.S. residents by asking questions related to these dimensions.
In the context of the immune system, the wellness model recognizes the importance of distinguishing between wellness and un-wellness by recognizing threat and initiating appropriate responses. This recognition of threat is done by cells of the innate immune system, which can identify pathogen-generated antigens as well as cellular debris and dysfunctional cells that need to be eliminated.
