CRITICAL THINKING
New research suggests a link between some microbes
that normally live in the body and seemingly unrelated
major illnesses. The gum disease called periodontitis itself
is not life-threatening, for instance, but it is a fairly good
predictor for heart attacks. Bacteria that cause gum disease
can trigger inflammation. Thinking back to your reading in
Chapter 7, how do you suppose that this response also may
be harmful to the heart?
1.
List and describe 4 types of innate immunity. Two of your answers should include examples of the body's first line of defense and two should include examples of the body's second line of defense
(2 types for examples of the body's first line of defense
2 types for examples of the body's second line of defense)

- Figure 42.11 Which of the following statements about T cells is false? Helper T cells release cytokines while cytotoxic T cells kill the infected cell. Helper T cells are CD4+, while cytotoxic T cells are CD8+. MHC II is a receptor found on most body cells, while MHC I is a receptor found on immune cells only. The T cell receptor is found on both CD4+ and CD8+ T cells.arrow_forward“T-lymphocytes are the most important arm of the immune response in protecting the community against virus infection.” Do you agree with this statement?
