1.Review and discuss the components of the cardiovascular systemthat play a role in the body’s defenses, as well as theirendocrine-related regulatory mechanisms as necessary. (Hint: theheart and blood vessels generally do not have well-characterizedbody defense roles. Also, the question should address extracellularbody defense components as well, not just cellular body defensecomponents.)
2. Discuss the components of innate and adaptive immunity,including a thorough review of their structures and functions. Inaddition, explain how autoimmune disorders and metastasizingcancers represent a failure of the two types of immunity, andreference the components previously described in this response asappropriate.
