Identify the factors that directly affect blood flow in the circulatory system

Cardiac output is the amount of blood ejected from the left or right ventricle in any given minute. Cardiac output must be maintained in order to keep sufficient blood flow through the capillaries. Identify the factors that directly affect blood flow in the circulatory system.

Describe the composition, physical characteristics, and functions of whole blood. Explain why it is classified as a connective tissue

Describe the composition, physical characteristics, and functions of whole blood. Explain why it is classified as a connective tissue.
Explain the similarities and differences among serum, lymph, and plasma. Each student should take one characteristic of the fluid, extracellular component of this connective tissue and explain how it relates to the other liquids.

How do the various elements of the nonspecific immune system function in providing daily protection against a variety of pathogens?

How do the various components of the lymphatic system operate? We have talked about many organ systems. In what ways are components of the lymphatic system involved in many other organ systems? Try to focus on one element of this system and provide an in-depth view of its contribution to our overall health.
How do the various elements of the nonspecific immune system function in providing daily protection against a variety of pathogens? Each student should provide a unique aspect of the nonspecific immune system and educate the rest of us concerning its function and how effective (or ineffective) it is against one class of pathogens

Discuss the issue of herd immunity and the risks in our modern society related to refusal to provide vaccinations.

Our knowledge and understanding of the various forms of lymphocytes continue to expand. Our initial discussion this week will be on the various forms of B and T cells — each of us should take one class of lymphocytes and explain it’s role in the adaptive immune process. As you comment on other students’ postings be sure to add additional insight into the mechanisms of the subclass of cell and its interactions with both components of the innate and other aspects of the adaptive immune system.
Vaccinations – Friend or Foe (graded)
Recently a number of individuals have claimed that adjuvants, such as thymersol in vaccines, lead to the development of a variety of disorders, such as autism. Although these initial claims have not been substantiated and have since been withdrawn from the scientific literature, the concern continues today. How would you counsel parents concerning vaccination? Discuss the issue of herd immunity and the risks in our modern society related to refusal to provide vaccinations.
