The Basics of Immunity
Until you get sick, you might not realize the importance of immunity in maintaining your health. Various immune cells, proteins, and chemicals, referred to as immune factors, protect you from potentially harmful environmental elements. As a result, some people may have a natural resistance or innate immunity to some diseases. For example, there are diseases that are prevalent in other species that do not pose a danger to humans such as feline leukemia. Yet, the body lacks immunity to other diseases such as small pox or measles. Regarding these diseases, humans require adaptive immunity in the form of a vaccination to prevent contraction of these diseases. Consider how your immune system and its various immune factors protect you from the numerous diseases you come into contact with daily.
For this Discussion, review this weekâ€™s Learning Resources. Then consider the similarities and differences between innate and adaptive immunity at the cellular level. Finally, select two immune factors from the following list that are involved in adaptive immunity, and consider how they are affected by adaptive immunity:
Natural Killer cells
With these thoughts in mind:
Post by Day 4 a comparison of innate and adaptive immunity. Include an example of a disease for which individuals may have innate immunity and a disease for which individuals may have adaptive immunity. Then, explain how adaptive immunity techniques might affect the two immune factors you selected. Finally, explain one method a health psychology professional might use to improve adaptive immunity in professional practice and why it might be effective. Be specific.
Be sure to support your post and responses with specific references to the Learning Resources.
